                                   SUBJECT TO COMPLETION, DATED JANUARY 22, 1998

                                                        1,733,815 SHARES

                                                   AMERICAN RIVERS OIL COMPANY

                                                          COMMON STOCK

     All of the 1,733,815  shares (the  "Shares") of the common stock,  $.01 par
value per share (the "Common Stock"),  of AMERICAN RIVERS OIL COMPANY, a Wyoming
corporation ("American Rivers" or the "Company"),  offered hereby are being sold
by the selling  shareholders  named  herein (the  "Selling  Shareholders").  The
registration  of the Shares  does not  necessarily  mean that any of such Shares
will be offered or sold by the Selling  Shareholders.  The Selling  Shareholders
may  sell  the  Shares  from  time to time in one or more  transactions,  in the
over-the-counter market or in privately negotiated  transactions,  including one
or more underwritten  offerings,  at fixed prices that may be changed, at market
prices  prevailing  at the time of offer and sale,  at  prices  related  to such
prevailing  market  prices  or at  negotiated  prices or a  combination  of such
methods of sale.  The  Selling  Shareholders  may effect  such  transactions  by
offering and selling the Shares directly to or through securities broker-dealers
in the over-the-counter market or otherwise, and such broker-dealers may receive
compensation  in the form of discounts,  concessions,  or  commissions  from the
Selling   Shareholders   or  the   purchasers   of  the  Shares  for  whom  such
broker-dealers may act as agent or to whom the Selling  Shareholders may sell as
principal, or both (which compensation as to a particular broker-dealer might be
in excess of  customary  commissions).  See "Selling  "Shareholders  and Plan of
Distribution."

     All Shares  offered  hereby were  issued by American  Rivers to the Selling
Shareholders in transactions  exempt from registration  under the Securities Act
of 1933, as amended (the "Securities Act").

     American  Rivers will  receive  none of the  proceeds  from the sale of the
Shares by the Selling Shareholders. American Rivers intends to bear all expenses
in connection with the  registration and sale of the Shares being offered by the
Selling   Shareholders   other   than   compensation   payable   to   securities
broker-dealers by the Selling  Shareholders or the purchasers of the Shares, any
securities  broker-dealer  expense allowances,  any fees and expenses of counsel
(and other  advisers)  to the  Selling  Shareholders  and  transfer  taxes.  The
offering  expenses to be paid by the Company are  estimated to be  approximately
$16,000.

     The Common Stock was delisted  from the Nasdaq  SmallCap  Market  effective
December 12, 1997 and is not traded on an exchange or listed on The Nasdaq Stock
Market  ("Nasdaq").  It is  traded  in the  over-the-counter  market on the "OTC
Bulletin Board" operated by Nasdaq.  As a result,  there is a limited market for
the  Shares,  which will have an adverse  effect on the future  sales  price and
liquidity  of the  Shares.  The last  reported  sale price for  Common  Stock on
January 13, 1998 was $0.109375 per share. See "Risk Factors -- No Active Trading
Market for the Common Stock."

     The Selling  Shareholders  and any agents,  broker-dealers  or underwriters
that  participate  in  the  distribution  of the  Shares  may  be  deemed  to be
"underwriters"  within the meaning of the  Securities  Act,  and any  commission
received by them and any profit on the resale of the Common  Stock  purchased by
them may be  deemed  to be  underwriting  discounts  or  commissions  under  the
Securities Act.

     THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK AND SHOULD
NOT BE PURCHASED BY INVESTORS WHO CANNOT BEAR THE LOSS OF THEIR ENTIRE
INVESTMENT.  SEE "RISK FACTORS" STARTING ON PAGE 4.

                                                       RISK FACTORS

     In  evaluating  an  investment  in the Common Stock being  offered  hereby,
prospective  investors  should  consider  carefully  all risks  and  speculative
factors affecting the Company and in particular, those affecting the oil and gas
industry,  before  deciding  whether or not to  purchase  the  securities  being
offered hereby. In addition,  prospective  investors should consider  carefully,
among other things, the following risk factors.

     History of Significant  Operating Losses and Anticipated Future Losses. The
Company has accumulated a deficit of approximately $3.9 million (unaudited). Net
operating  losses  have been  $640,027  for the year ended  December  31,  1996,
$936,378 for the year ended December 31, 1997, and  $2,361,663  (unaudited)  for
the six months ended  September 30, 1997.  Although a portion of such losses was
attributable to the Company's subsidiary, Bishop Capital Corporation ("Bishop"),
and even though  such  subsidiary  has been  spun-off,  the  Company  expects to
continue to operate at a loss until  sufficient new capital is obtained.  If the
Company is unable to secure adequate  additional capital on a timely basis, such
continued  losses would have a material  adverse  effect on the Company.  If the
Company  successfully  obtains  additional capital to finance the acquisition of
producing assets,  there can be no assurances that the revenues produced by such
assets will offset  historical  operating  losses or be  sufficient  to make the
Company profitable.

     No Active  Trading  Market for Common Stock.  The Company has been notified
that,  as of December  12, 1997,  the Common Stock was delisted  from the Nasdaq
SmallCap Market as the result of the Company's  failure to meet the tangible net
asset  requirements for continued listing.  Consequently,  the Common Stock will
now trade in the over-the-counter  market,  which is generally  characterized by
low trading volumes and high price and volume  volatility.  The Common Stock has
in the past and in the future is expected to  experience  significant  price and
volume  volatility.  Historically,  the Common  Stock has also  experienced  low
trading  volume and the  delisting of the Common Stock from the Nasdaq  SmallCap
Market is likely to cause the  trading  volume of the Common  Stock to  decrease
further,  which will  increase the risks of ownership of the Common  Stock.  Any
market for the Common  Stock can be expected to be volatile as is the market for
other  stocks  of small  companies  in the oil and gas  industry.  Many  factors
affecting  the Company,  the oil and gas industry or the stock market in general
may affect the price of the Common  Stock,  and the Company has no control  over
many of these factors.  Such factors may have a more  significant  effect on the
price of the Common Stock than on securities of other  companies for which there
is an active trading market.

     Need for Additional  Capital.  In December,  1997, the Company extended its
existing  credit  agreement  with  Vectra  Bank DTC  Branch  (formerly  known as
Professional  Bank).  As  of  December  29,  1997,  approximately  $540,000  was
outstanding  under such  credit  agreement,  all of which is due to be repaid on
March  12,  1998.  The  Company  will not have  sufficient  funds  generated  by
operations to repay the  outstanding  balance on March 13, 1998.  The Company is
seeking  replacement  financing,  but there can be no assurance  that the credit
agreement will be extended or that sufficient new financing will be available at
such time. Failure by the Company to timely extend the credit agreement or repay
the amounts  outstanding  when due would have a material  adverse  impact on the
Company's operations and financial condition.

     The Company's ability to acquire  additional oil and gas properties,  which
the Company intends to do in order to expand its reserve base, is dependent upon
the Company's ability to obtain the necessary  additional  capital.  The Company
intends to seek equity  financing in the amount of $1.5 to $4.0 million over the
next four to 12 months.  Until such time,  however,  the Company's believes that
its current cash flow will not be  sufficient  to satisfy its cash  requirements
for the next 12 months.  There can be no assurance  that  additional  sources of
financing  will  be  available  at  all or at a  reasonable  cost  and on  terms
satisfactory to the Company and the Company's ability to obtain equity financing
may be adversely  affected by the delisting of the  Company's  Common Stock from
trading on Nasdaq. Failure to obtain the necessary capital would have a material
adverse effect on the Company and its operations.

     Business Risks  Associated with the Oil and Gas Industry.  The Company must
continually  acquire and  explore  for and  develop new oil and gas  reserves to
replace  those being  depleted by  production.  Without  successful  drilling or
acquisition  ventures,  the  Company's  assets,  properties  and  revenues  will
decline. Oil and gas exploration and development are speculative, involve a high
degree of risk and are subject to all the hazards typically  associated with the
search for,  development  of and  production of oil and gas. These include risks
that: drilling operations will be unsuccessful, including the possibility that a
dry hole will be  drilled;  reserve  estimates  provided  to the  Company by its
contract  petroleum  engineers may not prove accurate;  existing  production may
cease;  well  casualties  could  occur;  and  domestic  and  worldwide  economic
conditions  (including the  applicability  of federal and state tax  incentives,
price controls,  and production  regulation) could make operations  commercially
unfeasible. In addition, during the past several years, as a result of worldwide
economic  conditions,  the price being paid for oil has fluctuated  dramatically
and remains  unpredictable.  Any one or more of such  factors  could  materially
adversely affect the

                                                           -4-

operations  and  financial  condition of the Company and could lead to continued
operating  losses even after the Company obtains  additional  capital to finance
its strategy to acquire producing assets.

     Previously, the Company emphasized development of infield drilling programs
on existing leases in established fields (the "River Prospects"),  which involve
drilling such prospects  with  horizontal and diagonal  drilling  technology,  a
process which has significant cost  uncertainties,  can be hazardous and carries
the risk that no commercially viable oil or gas production will be obtained. The
Company  now  intends  to shift its  focus  away  from the  River  Prospects  to
acquiring and further  developing  currently  producing oil and gas  properties.
There can be no  assurance  that the  Company  will be able to locate and obtain
such properties on commercially  reasonable  terms, or that such properties will
prove  successful.  Moreover,  the Company  may  experience  competition  in the
acquisition  and development of such properties from other oil and gas companies
with  resources  significantly  greater  than  those  of the  Company.  See "---
Competition."

     In general, drilling for oil and gas may be curtailed,  delayed or canceled
as the result of many  factors  beyond the  Company's  control  including  title
problems,  weather conditions,  shortages of or delays in delivery of equipment,
as well as the financial  instability of well operators,  major working interest
owners and well servicing companies.  Unseasonably cold weather in November 1997
reduced  production  levels in the D-J Basin by  approximately  $10,000  for the
month.  Normal  production  was resumed in  approximately  one week, but adverse
weather conditions could again affect production at any time.

     The  availability  of a ready  market  for the  Company's  oil and gas also
depends on numerous  factors  beyond its control,  including  the demand for and
supply of oil and gas, the  proximity of the  Company's  natural gas reserves to
pipelines,  the  capacity of such  pipelines,  fluctuations  in  production  and
seasonal demand,  the effects of inclement weather and governmental  regulation.
New gas  wells  may be  shut-in  for lack of a market  until a gas  pipeline  or
gathering  system with available  capacity is extended into the area and new oil
wells may have production curtailed until production facilities,  water disposal
facilities and delivery  arrangements  are acquired or developed.  The Company's
business will always be subject to these types of risks.

     Development  Risks and  Production.  A portion of the Company's oil and gas
reserves are Proved Undeveloped Reserves.  Successful development and production
of such reserves,  although they are categorized as "proved," cannot be assured.
Additional  drilling or  acquisitions  will be necessary in future years both to
maintain  production  levels  and to define the  extent  and  recoverability  of
existing reserves.  There can be no assurance that the Company's present oil and
gas  wells  will  continue  to  produce  at  current  or  anticipated  rates  of
production, that development drilling will be successful, that production of oil
and gas will commence when expected, or that there will be favorable markets for
oil and gas which may be produced by such wells in the future.

     Limitations on Accuracy of Reserve Estimates.  Estimates of reserves and of
future  net  revenues  prepared  by  different   petroleum  engineers  may  vary
substantially  depending, in part, on the assumptions made and may be subject to
adjustment  either up or down in the future.  The actual  amounts of production,
revenue, taxes, development expenditures,  operating expenses, and quantities of
recoverable  oil and gas reserves  may vary  substantially  from the  engineers'
estimates.  Oil and gas reserve  estimates are  necessarily  inexact and involve
matters of subjective engineering judgment. In addition, any estimates of future
net revenues and the present value thereof are based on  assumptions  derived in
part from historical price and cost  information,  which may not reflect current
and  future  values,  and on other  assumptions  made by the  Company  that only
represent its best estimate. If these estimates of quantities,  prices and costs
prove  inaccurate,  the Company is  unsuccessful  in  expanding  its oil and gas
reserves base with its  acquisitions,  or declines in and instability of oil and
gas prices occur,  then write downs in the capitalized costs associated with the
Company's oil and gas assets may be required.  Recently, the Company experienced
such write downs  caused by the  drilling of a dry hole on one of the  Company's
River  Prospects.  See "The Company."  There is no assurance that  additional or
further  reductions to the Company's  estimated  proved oil and gas reserves and
estimated  future net  revenues  will not be required  in the  future,  possibly
resulting  in  further  write  downs  of the  capitalized  costs  of oil and gas
properties.

     Price Volatility.  The Company's revenues are derived largely from the sale
of produced natural gas, natural gas liquids and oil and, as such, the Company's
revenues and  earnings  are affected by price levels at which these  commodities
are sold. The price levels at which oil and natural gas is sold are subject to a
number of  factors  beyond  the  Company's  control,  including,  among  others,
worldwide  and  domestic  supplies  of and  demand  for  oil  and  natural  gas,
production  guidelines and prices established by the members of the Organization
of  Petroleum  Exporting  Countries  ("OPEC"),  political  instability  or armed
conflict in the world's  oil-producing  regions,  the price and  availability of
alternative  fuels such as coal,  federal or state  taxes on the sale of oil and
natural  gas,  the  availability  of pipeline  capacity  and changes in existing
federal regulation and price controls.  As a result of these  fluctuations,  the
Company's  average  annual  sales  prices for oil,  natural  gas and natural gas
liquids,  has been erratic. It is very likely that these prices will continue to
fluctuate  in the future.  In late 1997 and  January  1998,  oil prices  dropped
significantly.  Approximately  one-third of the  Company's  revenues are derived
from the sale of oil. The Company

                                                           -5-

cannot predict whether the price of oil will remain low or, if so, for how long,
but continued low oil prices would adversely affect the Company's revenues.

     Operating Hazards and Uninsured Risks. The Company's operations are subject
to all of the risks incident to  exploration  for and production of oil and gas,
including blow-outs,  cratering, pollution and fires, each of which could result
in damage to or  destruction  of oil and gas wells or  production  facilities or
injury to persons and property.  The Company  currently  maintains  property and
liability  insurance  in the amount of $1.0  million and an  umbrella  insurance
policy in the amount of $2.0  million.  The  Company's  insurance  may not fully
cover certain of these risks, however, and the occurrence of a significant event
not fully insured against could have a material  adverse effect on the Company's
financial position and results of operations.

     Competition.  The  oil and  gas  industry  is  highly  competitive  in many
respects,  including  identification  of attractive  oil and gas  properties for
acquisition,  drilling and development,  securing  financing for such activities
and obtaining the necessary  equipment and personnel to conduct such  operations
and activities.  In seeking suitable opportunities,  the Company competes with a
number  of other  companies,  including  large oil and gas  companies  and other
independent  operators with greater financial resources and, in some cases, with
more  experienced  management.  Many other oil and gas companies in the industry
have financial resources,  personnel and facilities  substantially  greater than
those of the Company and there can be no assurance that the Company will be able
to compete  effectively  with these larger  entities.  Moreover,  the  Company's
intended  shift in its focus from River  Prospects  to the  acquisition  of more
conventional  producing  oil  and gas  properties  may  expose  the  Company  to
competitive  pressure  greater than that it previously  incurred when it focused
primarily on River Prospects.

     Dependence on  Acquisition of Additional  Leases.  Although the Company has
shifted its focus away from  developing  River  Prospects,  it may in the future
elect to pursue  some  River  Prospects.  Some  leases  pertaining  to the River
Prospects,  particularly  those  already  owned by the Company in Henderson  and
Union Counties,  Kentucky, and Pleasants and Tyler Counties, West Virginia, only
cover  one-half  of the River  Prospects  lying  under such  leases.  It will be
necessary to purchase  leases from  adjacent fee land owners or farmout from oil
companies  owning  existing  oil and gas leases  covering the other half of such
prospects.  There can be no  assurance  that the Company will be able to acquire
such additional leases at a reasonable cost, or at all. In the event the Company
is unable to acquire such  additional  leases,  the Company will only be able to
develop the portions of the prospect that it does have leased.

     Production  Requirements  under Leases.  Certain leases held by the Company
require drilling or production by the Company to avoid termination of the lease.
Although these provisions apply to a portion of the Company's leases,  there can
be no assurance  that the Company will drill by the  requisite  date or maintain
the requisite  production  levels.  The loss of such leases by the Company could
adversely effect the Company's results of operations and financial condition.

     Government  Regulation and Environmental  Risks. The production and sale of
oil and  natural  gas are  subject  to a  variety  of  federal,  state and local
government  regulations,  including  regulations  concerning  the  prevention of
waste,  the discharge of materials into the  environment,  the  conservation  of
natural gas and oil, pollution, permits for drilling operations, drilling bonds,
reports concerning operations, the spacing of wells, the unitization and pooling
of properties,  and various other matters,  including taxes. Many  jurisdictions
have at various times imposed  limitations  on the  production of gas and oil by
restricting  the rate of flow for gas and oil wells below their actual  capacity
to produce.  In addition,  many states have raised state taxes on energy sources
and  additional  increases may occur,  although  increases in state energy taxes
would have no  predictable  effect on natural  gas and oil  prices.  The Company
believes it is in substantial compliance with applicable environmental and other
governmental  laws and  regulations.  There can be no assurance,  however,  that
significant  costs for  compliance  will not be  incurred  by the Company in the
future,  thereby  having an  adverse  effect on the  ability  of the  Company to
conduct its business profitability.

     Control and  Anti-Takeover  Protections.  The Company's  Board of Directors
can, without  obtaining  shareholder  approval,  issue Shares of Preferred Stock
having rights that could adversely  affect the voting power of the Common Stock.
In addition,  the Company's Articles of Incorporation and Bylaws include certain
provisions,  the  effect of which may be to  inhibit a change in  control of the
Company.  The  provisions  include the  authorization  of additional  classes of
Preferred  Stock and  classification  of the Board of  Directors.  The  possible
issuance of shares of Preferred  Stock or additional  shares of Common Stock can
be used to oppose hostile takeover attempts.  In addition,  the concentration of
the  ownership  of the  Company's  Common  Stock is likely to prevent or delay a
hostile takeover attempt. See "Control by Present Shareholders."

     Dependence on One  Operator.  In the event  Arlian,  Inc.,  the operator of
certain wells of the Company, fails to comply with its letter agreement with the
Company,  or is  incapable  of  performing  its duties  pursuant  to such letter
agreement,  the  Company  believes  that it will  be very  difficult  to find an
operator to replace  Arlian,  Inc. on similar terms and the Company's  cash flow
from the D-J Basin  properties  could diminish.  In such case, the Company would
operate the wells or attempt to find an

                                                           -6-

<PAGE>



operator/partner  to replace  Arlian,  Inc.  under terms as close as possible to
those currently in effect with Arlian, Inc. There can be no assurance,  however,
that the Company could be able to find another operator on terms as favorable as
those currently in place with Arlian, Inc.

     Dependence  on  Key  Personnel.   The  Company's  planned   operations  are
significantly  dependent on a limited  number of  personnel,  including  Karlton
Terry,  (Chairman and Chief Executive Officer),  Rick Westerberg (President) and
Jubal  Terry (Vice  President,  Secretary-Treasurer).  Although  the Company has
entered into employment  agreements with these  individuals,  the failure by the
Company to retain the  services  of these  persons  may have a material  adverse
effect on the Company's operations.

     Stage of  Development.  The Company is at an early stage of development and
is subject to all of the risks  inherent  in the  development  of an oil and gas
business  enterprise.  To address  these risks,  the Company  must,  among other
things, adapt technological developments to its business, respond to competitive
developments, continue to attract, retain, and motivate qualified personnel, and
obtain additional capital to support the development of its business plan.

     Shares  Eligible for Future  Sale.  The Company has  outstanding  9,078,955
shares of restricted  Common Stock including  7,267,820 shares of Class B Common
Stock and  1,811,135  shares of Common Stock.  The Company also has  outstanding
1,864,635  shares of Common Stock that are not restricted under Rule 144. If all
of the Selling  Shareholders  sell all shares of Common  Stock  offered  hereby,
77,320 shares of Common Stock and 7,267,820  shares of Class B Common Stock will
be outstanding and constitute  restricted  securities under Rule 144. Commencing
in May 1998,  the Class B Common  Stock  will  become  convertible  in part into
Common  Stock.  In  November  1998,  all of the  Class B  Common  Stock  will be
convertible  into Common Stock.  To the extent the  restricted  or  unrestricted
shares of Common Stock,  including shares of Common Stock issued upon conversion
of the Class B Common Stock,  are sold by the selling  shareholders,  the market
price for the Company's securities may be adversely affected. Karlton Terry, the
Company's Chairman, has informed the Company that he is involved in negotiations
that may result in the sale of up to  5,228,000  shares of Class B Common  Stock
held by him and certain of his affiliates. See "The Company."

     Control by Present  Shareholders.  Upon  completion  of the  offering  made
hereby,  and  assuming  that  all of the  Shares  offered  hereby  are  sold  to
unaffiliated  third parties,  the present  officers and directors of the Company
and their affiliates will continue to control 68.4% of the outstanding shares of
the Company's Common Stock and Class B Common Stock. Consequently,  the officers
and directors and their  affiliates will continue to be able to exercise control
over the election of the Company's  directors,  the outcome of corporate actions
requiring shareholder approval,  the business and affairs of the Company and the
future  direction of the Company.  The  concentration of ownership of the Common
Stock and Class B Common Stock among the  Company's  officers and  directors and
their  affiliates  is likely to  prevent  or delay a change  of  control  of the
Company  without the consent of such  officers,  directors and  affiliates.  The
ownership of the  Company's  Common Stock and Class B Common Stock will continue
to be highly  concentrated  even  following the completion of a sale, if any, of
Class B Common Stock by Karlton Terry. See "The Company."

                                                        THE COMPANY

     American Rivers was incorporated  originally under the laws of the State of
Colorado on February 2, 1981,  as Metro Cable  Corporation.  On March 31,  1992,
American Rivers  reincorporated  in the State of Wyoming and changed its name to
Metro Capital  Corporation.  On December 12, 1995,  the Company closed its Asset
Purchase Agreement with Karlton Terry Oil Company, a Colorado  corporation,  and
certain individuals  (collectively,  "KTOC"), pursuant to which KTOC transferred
to the Company  certain  oil and gas  properties  in exchange  for shares of the
Company's Class B Common Stock (the "Asset Transfer").  As a result of the Asset
Transfer and pursuant to the Asset Purchase  Agreement,  the Company changed its
name to American Rivers Oil Company, and is now primarily engaged in the oil and
gas business.  The executive  offices of American Rivers are located at 700 East
Ninth Avenue,  Suite 106,  Denver,  Colorado 80203,  and its telephone number is
(303) 832-1117.

     American  Rivers  emerged in early 1996 with a specific  business plan that
involved  raising  funds  through  the  issuance  and  sale of  privately-placed
securities to initiate infield drilling programs on the River Prospects, acquire
producing  properties in the  Denver-Julesburg  Basin (the "D-J Basin"),  retire
existing  debt,  and for general  working  capital  purposes.  By February 1996,
however,  the Company's private placement funding effort raised only the minimum
capital  requirement,  the  proceeds  of which  were  used to retire  debt,  pay
existing expenses, and purchase certain D-J Basin properties.  At such time, the
market for the  Company's  shares was not  favorable,  trading in the  Company's
stock was not active  and  several  attempts  by the  Company  to raise  further
operating funds and enhance trading activity through local brokerage firms based
on the Company's business plan were unsuccessful.

     In  June  1996,  in an  effort  by the  Company's  management  to  maximize
shareholder  value,  American  Rivers  initiated  merger  discussions  with Opon
Development  Company ("ODC"), a private company that owned a small non-operating
interest  in a very  large,  highly  publicized  gas  field in  Colombia,  South
America.  From June 1996, American Rivers' management focused its efforts almost
exclusively  on the  potential  ODC merger for two  reasons:  (i) the  potential
growth in the Company's  asset value,  thereby  increasing the likelihood that a
viable public market in the Company's  stock would develop for the  shareholders
and (ii) the failure of the Company's private placement  fund-raising efforts to
raise additional  capital  necessary to complete American Rivers' drilling plans
for the River Prospects.  Negotiations with ODC continued for several months and
by December 1996, the tentative agreement provided that ODC and its shareholders
would own between a 90% and 95% interest in the new company to be created by the
proposed merger of ODC and the Company.

     By late fall  1996,  American  Rivers had raised  some  additional  private
placement funds that were earmarked to drill and acquire additional  properties,
pay off debt to Bishop Capital Corporation ("Bishop"), a wholly-owned subsidiary
of the Company created as part of the Asset Transfer,  and to be used as working
capital to support  the  proposed  ODC merger.  In December  1996 when the total
asset ratio  between ODC and the Company was being  finalized and the merger was
approved by the Board and certain key  shareholders,  American Rivers management
engaged Rothschild Natural Resources to review the proposed transaction and give
an opinion that the transaction was fair to American Rivers' shareholders.

     In February  1997,  American  Rivers  drilled an offset to a producing well
located in the Lake Hatch field in Terrebonne Parish, Louisiana,  based on a 3-D
seismic  structure.  The  potential  producing  sand  structurally  was  low  to
prognosis and the well was therefore nonproductive. In April 1997 the ODC merger
reached a critical  point and closing  negotiations  came to an abrupt end.  ODC
decided not to continue with the merger,  citing  significant  resistance on the
part of certain of the Company's  shareholders  and  representatives  of certain
shareholders.  The  failure  of this  proposed  merger  left  the  Company  with
significant expenses and nothing to show for nine months of work.

     American Rivers  continued to try and complete a drilling program on one of
its River  Prospects by drilling  the Sparkle #2 well.  In order to complete the
drilling operation,  Karlton Terry, the Company's  Chairman,  loaned the Company
$53,500 at an interest rate of 5% per annum.  This well  represented the best of
three proved  undeveloped wells in the Company's  reserve reports.  The well was
drilled in August 1997, and proved to be a dry hole as a result of a significant
change in the sand  composition  at the crest of the geological  structure.  The
operation  resulted in a write down to the Company of $1,936,300.  Subsequent to
the  write  down  of  value  on such  prospect,  a  re-evaluation  of all of the
Company's  assets was  undertaken,  resulting in further write downs totaling an
additional $339,140,  which includes $224,761 attributable to the Company's loss
of the  Bayou  Chauvin  lease  due to  lack of  operations  by the  operator.  A
re-evaluation  of the  anticipated  life of the D-J wells  further  reduced  the
Company's asset value.

     Effective  October 1, 1997,  American  Rivers sold its interest in its Lake
Hatch Field for $418,000, representing a gain of $85,100 that will be recognized
in the quarter ended December 31, 1997. The Company used approximately  $233,000
of the proceeds of such sale to reduce its debt from  $750,000 to $517,000.  The
Company  used  another  $30,000 of such  proceeds to repay a portion of the loan
made by Karlton Terry in connection  with the  completion of the Sparkle #2 well
and used the remainder of such proceeds to pay trade payables. See "Risk Factors
- - Need for Additional Capital."

     Although some viable River Prospects remain,  because results from drilling
the  River  Prospects  have  not  met the  Company's  expectations  and  because
management  believes it had lost  substantial  market support as a result of its
ODC merger attempts, the Company has shifted its emphasis to acquiring producing
assets.  Such new effort will be targeted  with the  intention of improving  the
Company's results of operations. The Company has hired a Petroleum Engineer, Mr.
Rick Westerberg, to serve as President, with a mandate that he initiate activity
in  acquisitions  and growth.  The Company  believes that Mr.  Westerberg  has a
proven  track  record and is  experienced  in  acquiring  oil and gas  producing
properties.  With a view to supporting the Company's new direction,  Mr. Michael
Humphries of Rothschild Natural Resources has consented to join the Board.

     American  River's  Chairman of the Board of Directors,  Karlton Terry,  has
informed the Company that he is negotiating  with a private party to sell all of
the  shares of Class B Common  Stock  held by him,  together  with all shares of
Class B Common Stock held by KTOC and a charitable  organization founded by him,
representing  an  aggregate  of 5,228,000  shares of Class B Common  Stock.  The
holders of Class B Common  Stock are  entitled  generally as a single class with
the holders of the Common Stock and, accordingly,  a sale of such Class B Common
Stock by Mr. Terry and KTOC would constitute a change in control of the Company.
No definitive  agreement with respect to such sale has been reached however, and
the Company  cannot  predict  whether any such  agreement will be reached or the
timing of any such sale if an  agreement  is reached.  Moreover,  Mr.  Terry has
informed  the Company  that the status of such  negotiations  is such that it is
uncertain whether all or only a portion of the shares held by him and such other
parties would be sold if an agreement is reached.

                                                      USE OF PROCEEDS

     The Company  will  receive no  proceeds  from the sale of the Shares by the
Selling Shareholders.

                                                   SELLING SHAREHOLDERS

     The following  table sets forth certain  information  regarding the Selling
Shareholders and the Shares offered by the Selling Shareholders pursuant to this
Prospectus. Because the Selling Shareholders may sell all, some or none of their
Shares,  no estimate  can be made of the number of Shares that are to be offered
hereby or that will be owned by each Selling  Shareholder upon completion of the
offering to which this Prospectus relates.

     Of the 1,733,815 Shares being offered hereby,  1,217,500 Shares were issued
and sold by the Company in a private  placement  transaction  that was closed on
November  9,  1996.   Another   450,000   Shares  were  issued  to  two  Selling
Shareholders,  Francarep,  Inc. and Haddon,  Inc. in  connection  with the Asset
Transfer as  consideration  for certain  interests  in wells and leases owned by
them  that  were  transferred  to the  Company  in  conjunction  with the  Asset
Transfer.  The remaining  66,315 Shares have been issued and sold by the Company
in several separate  transactions,  primarily in connection with the acquisition
by the Company of interests leases and wells.

                                                   PLAN OF DISTRIBUTION

         The Selling  Shareholders'  Shares may be offered and sold from time to
time in the discretion of the Selling Shareholders. The Selling Shareholders may
sell  the  Shares  from  time  to  time  in one  or  more  transactions,  in the
over-the-counter market or in privately negotiated  transactions,  including one
or more underwritten  offerings,  at fixed prices that may be changed, at market
prices  prevailing  at the time of offer and sale,  at  prices  related  to such
prevailing  market  prices  or at  negotiated  prices or a  combination  of such
methods of sale. The Selling  Shareholders will act independently of the Company
in making  decisions  with  respect to the timing,  manner and size of each sale
hereunder.  The Selling  Shareholders'  Shares may be sold by one or more of the
following methods,  without  limitation:  (i) a block trade in which a broker or
dealer so engaged  will attempt to sell the Shares as agent but may position and
resell a portion of the block as principal to facilitate the  transaction;  (ii)
purchases by a broker or dealer as principal and resale by such broker or dealer
for  its  account  pursuant  to  this  Prospectus;   (iii)  ordinary   brokerage
transactions and transactions in which the broker solicits  purchases;  and (iv)
face-to-face   transactions   between   sellers   and   purchasers   without   a
broker/dealer.  In effecting  sales,  brokers or dealers  engaged by the Selling
Shareholders  may  arrange  for other  brokers or dealers to  participate.  Such
brokers  or  dealers  may  receive   commissions   or  discounts   from  Selling
Shareholders in amounts to be negotiated. Such brokers and dealers and any other
participating  brokers or dealers may be deemed to be "underwriters"  within the
meaning of the Securities Act, in connection with such sales.

         Sales of certain of the Selling  Shareholders'  Shares may also be made
pursuant to Rule 144 under the Securities Act. The Shares may also be offered in
one or more underwritten  offerings, on a firm commitment or best efforts basis.
The Company will receive no proceeds  from the sale of the Shares by the Selling
Shareholders.  The  Shares  may be  sold  from  time  to  time  in  one or  more
transactions  at a fixed  offering  price,  which may be changed,  or at varying
prices determined at the time of sale or at negotiated prices.  Such prices will
be  determined  by the Selling  Shareholders  or by agreement  between a Selling
Shareholder and its underwriters, dealers, brokers or agents.

         To the extent required under the Securities  Act, the aggregate  amount
of Shares  being  offered and the terms of the  offering,  the names of any such
agents,  brokers,  dealers or  underwriters  and any applicable  commission with
respect to a particular  offer will be set forth in an  accompanying  Prospectus
Supplement.  Any underwriters,  dealers,  brokers or agents participating in the
distribution of the Shares may receive  compensation in the form of underwriting
documents,  concessions,  commissions  or fees  from a  Selling  Shareholder  or
purchasers of Shares, for whom they may act. In addition, sellers of Shares

                                                           -10-

may be deemed to be  discount  commissions  under the  Securities  Act.  Selling
Shareholders  may have other  business  relationships  with the  Company and its
subsidiaries or affiliates in the ordinary course of business.

         From time to time one or more of the Selling Shareholders may transfer,
pledge,  donate or assign Shares to lenders,  family members and others and each
of such  persons  will be deemed to be a "Selling  Shareholder"  for purposes of
this  Prospectus.  The  number of  Shares  beneficially  owned by those  Selling
Shareholders who so transfer,  pledge,  donate or assign Shares will decrease as
and when  they take such  actions.  The plan of  distribution  for  Shares  sold
hereunder  will  otherwise  remain  unchanged,   except  that  the  transferees,
pledgees, donees or other successors will be Selling Shareholders hereunder.

                                                       LEGAL MATTERS

         The validity of the  issuance of the shares of Common  Stock  described
herein  will be passed  upon for  American  Rivers by Holme  Roberts & Owen LLP,

Item 14.  Other Expenses of Issuance and Distribution

         The  following  table  shows the  estimated  expenses to be incurred in
connection with the issuance of the securities being registered:


Registration Fee--SEC                                  $    72
Accountants' Fees and Expenses                         $ 4,000
Legal Fees and Expenses                                $10,000
Miscellaneous                                          $ 2,000
                  Total Costs                          $16,072

All of the above expenses except the SEC registration fee are estimates.

Item 15.  Indemnification of Directors and Officers

     The  Company's  Articles of  Incorporation  provide that the Company  shall
indemnify any person who is or was a director to the maximum extent  provided by
statute.   Pursuant  to  Wyoming  Business   Corporation  Act  ("WBCA")  Section
17-16-851,  a  corporation  may  indemnify a person made a party to a proceeding
because he is or was a director against liability incurred in the proceeding if:
(i) he conducted himself in good faith and reasonably  believed that his conduct
was in or at least not opposed to the corporation's best interests; and, (ii) in
the case of a criminal  proceeding,  he had no  reasonable  cause to believe his
conduct was  unlawful.  A  corporation  may not  indemnify  a  director:  (i) in
connection  with a proceeding by or in the right of the corporation in which the
director was adjudged liable to the corporation; or, (ii) in connection with any
other  proceeding  charging  improper  personal  benefit to him,  whether or not
involving  action in his official  capacity,  in which he was adjudged liable on
the basis that personal benefit was improperly received by him.

     The  Company's  Articles of  Incorporation  provide that the Company  shall
indemnify  any person who is or was an officer and not a director to the maximum
extent  provided by law, or to a greater  extent if  consistent  with law and if
provided by  resolution  of the Company's  shareholders  or  directors,  or in a
contract.  Pursuant to WBCA Section  17-16-856,  a  corporation  may indemnify a
current or former officer who is not a director to the extent,  consistent  with
public policy,  that may be provided by its articles of  incorporation,  bylaws,
general or specific action of its board of directors or contract.

Item 17.  Undertakings

     The undersigned Registrant hereby undertakes:

     (a) to file,  during any period in which  offers or sales are being made, a
post-effective  amendment to this Registration Statement to include any material
information with respect to the plan of distribution not previously disclosed in
the  Registration  Statement or any material  change to such  information in the
Registration Statement;

     (b) that for the purpose of  determining  any liability  under the Act each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof;

     (c) to remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering; and

     (d) that,  for purposes of determining  any liability  under the Securities
Act, each filing of the registrant's  annual report pursuant to section 13(a) or
section  15(d) of the  Exchange  Act that is  incorporated  by  reference in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as  indemnification  for  liabilities  arising under the Act may be
permitted to  directors,  officers  and  controlling  persons of the  Registrant
pursuant to the foregoing  provisions,  or otherwise,  the  Registrant  has been
advised  that in the opinion of the  Securities  and  Exchange  Commission  such
indemnification  is  against  public  policy  as  expressed  in the  Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant

                                                           II-2

of expenses incurred or paid by a director, officer or controlling person of the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such director,  officer or controlling person in connection with the
