	The Selling Shareholders will offer their Common  Stock through or to 
securities brokers or dealers designated by them in the over-the-counter market 
or in other transactions negotiated by the Selling Shareholders.  Any such sale 
of Common Stock by Selling Shareholders must be accompanied by, or follow the 
delivery of, a prospectus filed with a current registration statement relating 
to the Common Stock being offered, unless a Selling Shareholder elects to rely 
on Rule 144 or another exemption from the registration requirements in 
connection with a particular transaction.  The Selling Shareholders and any 
broker, dealer, or agent that participates with the Selling Shareholders in the 
sale of Common Stock  offered hereby may be deemed "underwriters" within the 
meaning of the Securities Act of 1933, as amended ( the "Securities Act"), and 
any commission or discounts received by them and any profit on the resale of the
Common Stock purchased by them may be deemed to be underwriting commissions 
under the Securities Act. (See "SELLING STOCKHOLDERS" and "PLAN OF 
DISTRIBUTION").

</TABLE>

(1)  The price per share for the securities offered by the Selling Shareholders 
is estimated at the closing sales price quoted by Nasdaq for the Common Stock at
$2.75 on April 14, 1997.  The Common Stock may be offered at the current market 
price, which may vary through the period during which the securities may be 
offered, or at such other prices as may be negotiated by the Selling Shareholder
and the purchaser at the time of sale. 
(2)  The securities to be sold by Selling Stockholders may be sold by them or 
through or to securities brokers or dealers, which sales may involve the payment
of commissions to the Selling Stockholders.
(3)  Does not reflect expenses of this offering payable by the Company estimated
at $7,000 nor the receipt by the Company of approximately $928,000 on the 
exercise of options.  (See "PLAN OF DISTRIBUTION" below).

	The Company will not receive any proceeds from the sale of Common Stock by 
the Selling Stockholders.  However, the Company would receive proceeds upon 
exercise of options held by Selling Stockholders prior to the sale of Common 
Stock issuable on such exercise.  (See "USE OF PROCEEDS").  In connection with 
this offering, the Company estimates that it will incur costs of approximately 
$7,000 for legal, accounting, printing, and other costs.  Any separate costs of 
Selling Stockholders will be borne by them.  Commissions or discounts paid in 
connection with the sale of securities by the Selling Stockholders will be 
determined by negotiations between them and the broker-dealer through or to 
which the securities are to be sold and may vary depending on the broker-
dealers' commission or mark up schedule, the size of the transaction, and other 
factors.  (See "PLAN OF DISTRIBUTION" below.)

	The Selling Stockholders and any broker, dealer, or agent that participates 
with the Selling Stockholders in the sale of the Common Stock offered hereby may
be deemed "underwriters" within the meaning of the Securities Act of 1933, as 
amended ( the "Securities Act"), and any commission or discounts received by 
them and any profit on the resale of the Common Stock purchased by them may be 
deemed to be underwriting commissions under the Securities Act. (See "SELLING 
STOCKHOLDERS" and "PLAN OF DISTRIBUTION").

THE COMPANY
Earth Sciences, Inc. (the "Company") is a diversified mineral exploration and 
development company specializing in mineral exploration and chemical processing 
with planned production of purified phosphate products in Calgary.  The Company 
was incorporated under the name of Colorado Central Mines, Inc. in Colorado in 
1957.  Current activities of the Company include (1) modification of its solvent
extraction facility in Calgary, Alberta for production of purified phosphate 
products scheduled to commence in May 1997; (2) continued exploration activities
for gold resources in Venezuela including its land contract covering 
approximately 1200 acres; (3) drilling and further geologic evaluation of the 
Cerro Gordo property in Inyo County, California (4) the planned acquisition of 
ADA Environmental Solutions LLC, a company that provides flue gas conditioning 
technology for coal-fired boilers and other applications, and (5) maintenance of
its position in several mining deposits and prospects in the Western US.

The Company's solvent extraction facility in Calgary, Alberta, recovered uranium
from phosphoric acid during the period from 1983 through 1987.  Uranium oxide 
production was suspended in the fall of 1987 when the adjacent fertilizer plant 
from which the facility received its feed stock suspended operations.  The 
contract under which the uranium was sold was modified in 1990 to allow 
unrestricted alternative use of the facility.  An in-house feasibility study, 
completed in 1995, confirmed the technical and financial feasibility of 
conversion of the facility for the production of purified phosphate products.  
Revamp of the facility to allow such production is currently underway.  Start-up
activities are expected to commence in April 1997 with product expected to be 
available for sale in May 1997.  There can be no assurances that the Company 
will be able to maintain the expected schedule.
  
RECENT DEVELOPMENTS

Investor Relation Services
In August 1996, the Company engaged Corporate Relations Group, Inc. ("CRG") of 
Winter Park, Florida to provide investor relation services for the Company over 
a 5 year period.  The services include wide circulation advertising, broker 
relations and direct marketing.  In addition to certain cash payments, the 
Company issued CRG 100,000 shares of Common Stock and options to purchase 
300,000 shares of Common Stock at prices ranging from $2.00 to $4.00 per share. 
This Prospectus includes the resale of shares of Common Stock held by CRG and 
those issuable by the Company on the conversion of such options.

Sale of Convertible Debentures
In March and April 1997, the Company issued $3,645,000 of 4% convertible 
debentures (the "Debentures") for which the Company received net proceeds of  
approximately $3,316,000.  Interest is payable quarterly.  The Debentures are 
convertible at any time following 45 days after the issuance thereof.  
Debentures amounting to $550,000 mature on March 31, 1998, while the balance of 
the Debentures issued mature on March 31, 1999.  The Debentures are convertible 
into shares of Common Stock based on a 25% discount from the market price of the
Common Stock at the time of conversion, but not in excess of $3.13 and $3.25 per
share, respectively.  The Company may repurchase the Debentures at a 25% premium
under certain circumstances.  This Prospectus includes the resale of shares of 
Common Stock  issuable by the Company on the conversion of the Debentures.

The principal executive offices of the Company are located at 910 12th Street, 
Golden, Colorado  80401, and its telephone number is (303) 279-7641.

________________________________________________________________________________

RISK FACTORS
An investment in the Shares is speculative and involves a high degree of risk.  
In analyzing the offering, prospective investors should read this entire 
Prospectus and the information incorporated herein by reference, and carefully 
consider, among others, the following risk factors in addition to the other 
information set forth elsewhere in this Prospectus.

Specifics Risks Related to the Company
No Dividends.  The Company has paid no cash dividends on its Common Stock and 
has no present intention of paying cash dividends in the foreseeable future.  It
is the present policy of the Board of Directors to retain all earnings to 
provide for the growth of the Company.  Payments of cash dividends in the future
will depend, among other things, upon the Company's future earnings, 
requirements for capital improvements, the operating and financial conditions of
the Company and other factors deemed relevant by the Board of Directors.

Lack of Profitability.  While the Company reported net income in fiscal 1995, 
the Company's operating history has resulted in losses from operations in the 
fiscal years ending December 31, 1988 through 1994 and in 1996.  While certain 
of the Company's operations may be profitable during a given fiscal year, the 
Company's operations as a whole may be unprofitable due to exploration and 
development costs on properties from which no revenue is derived, to continuing 
corporate general and administrative costs and to interest expense associated 
with long term debt.

Issuance of Additional Shares.  The Board of Directors has the authority to 
authorize the offer and sale of additional securities without the vote of or 
notice to existing shareholders, and it is likely that additional securities 
will be issued to provide future financing or in connection with acquisitions.  
The issuance of additional securities could dilute the percentage interests and 
per share book value of existing shareholders, including persons purchasing 
securities in this offering. 

Volatility of Price for Common Stock.  The market price for shares of the 
Company's Common Stock may be highly volatile depending on news announcements or
changes in general market conditions.  In recent years the stock market has 
experienced extreme price and volume fluctuations.

Risks Related to the Exploration and Development of Minerals
Nature of Mineral Exploration and Development.  Exploration for minerals is 
highly speculative and may involve greater risks than many other businesses.  
Many exploration programs, including those which have been conducted by the 
Company, do not result and have not resulted in the discovery of mineralization 
and any mineralization discovered may not be of sufficient quantity or quality 
to be profitably mined.  The Company's mineral exploration and development 
activities are subject to all of the operating hazards and risks normally 
incident to such activities, such as encountering unusual or unexpected 
formations, environmental pollution, personal injury and flooding.  All of these
factors may result in losses in relation to the amounts spent which are not 
recoverable.

Competition and Scarcity of Mineral Lands.  Many companies and individuals are 
engaged in mineral exploration and development, including large, established 
mining companies with substantial capabilities and long earnings records.  There
is a limited amount of desirable mineral lands available for claim staking, 
lease or other acquisition in the United States ("US"), Venezuela and other 
areas where the Company contemplates conducting exploration activities.  The 
Company may be at a competitive disadvantage in acquiring mineral properties 
since it must compete with these individuals and companies, many of which have 
greater financial resources and larger technical staffs than the Company.  From 
time to time, specific properties or areas which would otherwise be attractive 
to the Company for exploration or acquisition are unavailable due to their 
previous acquisition by other companies.

Fluctuation in the Price of Minerals.  The market price of minerals is extremely
volatile and beyond the control of the Company.  Gold prices are generally 
influenced by basic supply/demand fundamentals.  The market dynamics of 
supply/demand can be heavily influenced by economic policy, i.e., central banks 
sales/purchases, political unrest, conflicts between nations, and general 
perceptions about inflation.  Fluctuating metal prices may have a significant 
impact on the Company's results of operations and operating cash flow.  
Furthermore, if the price of a mineral should drop dramatically, the value of 
the Company's properties which are being explored or developed for that mineral 
could also drop dramatically, and the Company might not be able to recover its 
investment in those properties.  The decision to put a mine into production, and
the commitment of the funds necessary for that purpose, must be made long before
the first revenues from production will be received.  During the last five 
years, the average annual market price of gold has fluctuated between $344 per 
ounce and $384 per ounce.  Price fluctuations between the time that such a 
decision is made and the commencement of production can change completely the 
economics of the mine.  Although it is possible to protect against price 
fluctuations by hedging in certain circumstances, the volatility of mineral 
prices represents a substantial risk in the mining industry generally which no 
amount of planning or technical expertise can eliminate.

Environmental Controls.  Compliance with environmental quality requirements and 
reclamation laws imposed by federal, state, provincial, and local governmental 
authorities may necessitate significant capital outlays, may materially affect 
the economics of a given property, or may cause material changes or delays in 
the Company's intended activities.  New or different environmental standards 
imposed by any governmental authority in the future may adversely affect the 
Company's activities.

Uncertainty of Title.  Several of the Company's mining properties which are in 
the United States are unpatented mining claims to which the Company, or those 
under which the Company holds its rights, has only possessory title.  Because 
title to unpatented mining claims is subject to inherent uncertainties, it is 
difficult to determine conclusively ownership of such claims.  Since a 
substantial portion of all mineral exploration, development and mining in the 
United States now occurs on unpatented mining claims, this uncertainty is 
inherent in the mining industry.  In addition, in order to retain title to an 
unpatented mining claim, a claim holder must have met annual assessment work 
requirements ($100 per claim) through September 1, 1992 and must have complied 
with stringent state and federal regulations pertaining to the filing of 
assessment work affidavits.  Moreover, after September 1, 1992, the right to 
locate or maintain a claim generally is conditional upon payment to the United 
States of a rental fee of $100 per claim per year for each assessment year 
instead of performing assessment work.  State law may, in some instances, still 
require performance of assessment work.

The present status of the Company's properties as unpatented mining claims 
located on public lands of the U.S. allows the claimant the exclusive right to 
mine and remove valuable minerals, such as precious and base metals and 
industrial minerals, found therein, and also to use the surface of the land 
solely for purposes related to mining and processing the mineral-bearing ores.  
However, legal ownership of the land remains with the U.S.  Accordingly, with an
unpatented claim, the U.S. retains many of the incidents of ownership of land, 
the U.S. regulates use of the surface, and the Company remains at risk that the 
claims may be forfeited either to the U.S. or to rival private claimants due to 
failure to comply with statutory requirements as to locations and maintenance of
the claims.  If there exists a valuable deposit of locatable minerals (which is 
the requirement for the unpatented claim to be valid in the first place), and 
provided certain levels of work and improvements have been performed on an 
unpatented mining claim, the Mining Law of 1872 authorizes claimants to then 
seek to purchase the full title to the claim, thereby causing the claim to 
become the private property of the claimant.  Such full ownership expands the 
claimant's permissible uses of the property (to any use authorized for private 
property) and eliminates the need to comply with maintenance and reporting 
requirements necessary to protect rights in an unpatented claim.

Proposed Legislation Affecting the Mining Industry.  For the last several 
Congressional sessions, bills have been repeatedly introduced in the U.S. 
Congress which would supplant or radically alter the provisions of the Mining 
Law of 1872.  As of March 31, 1997, no such bills have passed, although a number
of differing and sometimes conflicting bills are now pending.  If enacted, such 
legislation could substantially increase the cost of holding unpatented mining 
claims and could impair the ability of companies to develop mineral resources on
unpatented mining claims.  Under the terms of certain proposed legislation, the 
ability of companies to obtain a patent on unpatented mining claims would be 
nullified or substantially impaired.  Moreover, certain forms of such proposed 
legislation contain provisions for the payment of royalties to the federal 
government in respect of production from unpatented mining claims, which could 
adversely affect the potential for development of such claims and the economics 
of operating existing mines on federal unpatented mining claims.  The Company's 
financial performance could therefore be affected adversely by passage of such 
legislation.  It is impossible to predict at this point what any legislated 
royalties might be, but a potential three to four percent gross royalty, 
assuming a gold price of $400 per ounce, would have an approximated $12 to $16 
per ounce impact on the Company's costs of any production from unpatented mining
claims. 

Uncertainty of Funding for Exploration.  The Company has funded much of its 
exploration and acquisition activities through joint venture arrangements, which
minimize the cost of such activities to the Company and allow it to explore and 
acquire a greater number of properties than it would otherwise be able to 
explore or acquire on its own.  The Company has also funded a portion of its 
exploration activities without joint venture participation, resulting in 
increased costs to the Company.  The Company has been successful in raising such
funds for its exploration activities.  Additional funding from existing partners
or third parties, however, may be necessary to conduct detailed and thorough 
evaluations of, and to develop certain properties.  The Company's ability to 
obtain this financing will depend upon, among other things, the price of gold 
and the industry's perception of its future price.  Therefore, availability of 
funding is dependent largely upon factors outside of the Company's control, and 
cannot be accurately predicted.  The Company does not know from what sources it 
will derive any required funding.  If the Company is not able to raise 
additional funds (as to which there can be no assurance), it will not be able to
fund certain exploration activities on its own.

Uncertainty of Development and Operating Property Economics and Ore Grades at 
Development Properties.  Decisions as to whether any of the mineral development 
properties which the Company now holds or which it may acquire in the future 
contain commercially minable deposits, and whether such properties should 
therefore be sold or brought into production, depend upon the results of 
exploration programs and/or feasibility analyses and the recommendations of duly
qualified engineers or geologists.  Such decisions involve consideration and 
evaluation of several significant factors, including, but not limited to, the 
(a) costs of bringing a property into production, including exploration and 
development work, preparation of production feasibility studies and construction
of production facilities, (b) availability and costs of financing, (c) ongoing 
costs of production, (d) market prices for the mineral to be produced, and (e) 
the amount and grades of reserves or mineralized material.  There can be no 
assurance that any of the development properties now held by the Company, or 
which may be acquired by the Company, contains a commercially minable mineral 
deposit, and therefore no assurance that the Company will ever generate a 
positive cash flow from the sale of or production operations on such properties.
In addition, once a property is sold with a retained royalty or placed into 
production, risks still exist that the amount and grade of its reserves will not
actually be as predicted.  To the extent that lower amounts and/or grades of 
reserves are experienced, costs per unit produced and profitability can be 
adversely affected.  Depending upon the extent of such an effect in any of the 
Company's properties, the Company could incur a writedown on its investment in 
any such property.

Termination of Mining at the San Luis Gold Mine.  Royalty income from the San 
Luis gold mine has been the only significant source of income for the Company 
for the last five years.  The mine is leased to and operated by Battle Mountain 
Gold Co. ("BMGC").  As reported to the Company by BMGC, mining was completed at 
the end of October, 1996.  The Company's royalty income from the property ceased
shortly after that time.

Risks Related to the Production and Sale of Purified Phosphate Products

Technical Aspects of Purified Phosphoric Acid Production.  The solvent 
extraction process developed by the Company for the production of purified 
phosphoric acid ("PPA") has not been proven on a commercial basis at the Calgary
plant.  Although the Company has performed numerous bench-scale and pilot plant 
test of the process, there can be no assurances that the process will yield 
satisfactory results when employed on a commercial scale.

Limited Experience in Marketing Industrial Chemicals and Lack of Long-term Sales
Contracts.  The growth and profitability of operations at the Company's solvent 
extraction facility in Calgary will be dependent upon, among other things, the 
sale of purified phosphate products to chemical distributors and customers.  The
Company has limited experience in marketing industrial chemicals and will be 
relying on consultants and others to initiate and maintain sales contacts.  PPA 
is not typically sold under long-term contracts, and the Company does not have 
any long-term commitments to purchase its planned products.  There can be no 
assurances that the Company will be successful in its sales efforts.

Supply of Raw Materials. The growth and profitability of operations at the 
Company's solvent extraction facility in Calgary will be dependent upon, among 
other things, the availability of sufficient raw materials at reasonable prices.
The Company has negotiated renewable annual supply contracts with Agrium U.S. 
Inc. ("Agrium") and Farmland Industries ("Farmland") to supply the estimated 
requirement of superphosphoric acid ("SPA").  The contracts with Agrium and 
Farmland both contain provisions that allow extension of the contracts in the 
future or termination upon a several month written notice.  There can be no 
assurances that the Company will be able to extend these contracts in the future
and obtain sufficient quantities of SPA at reasonable prices.

Ability to Expand Geographically. The growth and profitability of operations at 
the Company's solvent extraction facility in Calgary will be dependent upon, 
among other things, the ability to become the predominate supplier of PPA in the
geographic region surrounding Calgary and on the US West Coast, and to sell on 
an increasing basis to the Minneapolis/Chicago area.  There can be no assurance 
that the Company's efforts to expand sales can be accomplished on a profitable 
basis.

Competition.  The Company's purified phosphate products will be sold in markets 
that are highly competitive.  The principal competitive factors include product 
quality, price and distribution capabilities.  There can be no assurances that 
the Company will be able to compete successfully against current and future 
competitors based on these factors.  The Company will compete with several 
domestic and international producers, many of whom have substantially greater 
financial, production, distribution and marketing resources than the Company. 
Increased competition could result in price reductions, reduced margins and loss
of market share, all of which could have a material adverse affect on the 
Company's business, financial condition and results of operations.

PLAN OF DISTRIBUTION

This Prospectus relates to the public offer and sale by certain shareholders 
(the "Selling Shareholders") of an aggregate of 3,036,354 shares of Common Stock
of the Company issuable on conversion of the Debentures for a maximum of 
2,463,334 shares of Common Stock, upon the exercise of options to purchase 
339,000 shares of Common Stock and 234,020 shares of Common Stock currently held
by Selling Shareholders.	

The Common Stock to be sold by the Selling Shareholders  may be sold by them 
from time to time directly to purchasers.  Alternatively, the Selling 
Shareholders may, from time to time, offer the Common Stock through dealers or 
brokers, who receive compensation in the form of commissions from the Selling 
Shareholders and/or the purchasers of the Common Stock for whom they act as 
agents.  As of the date hereof, no Selling Shareholder has advised the Company 
that it has entered into any agreement or understanding with any dealer or 
broker for the offer or sale of the Common Stock.  The Selling Shareholders may 
enter into such agreements or understandings in the future.  The Selling 
Shareholders may also offer some or all of the Common Stock through market 
transactions on Nasdaq, on which the Company's Common Stock is traded.  Sales of
the Common Stock through brokers may be made by any method of trading authorized
by Nasdaq, including block trading in negotiated transactions.  Without limiting
the foregoing, such brokers may act as dealers purchasing any or all of the 
Common Stock covered by this Prospectus.  Sales of Common Stock are, in general,
expected to be made at the market price prevailing at the time of each such 
sale; however, prices in negotiated transactions may differ considerably.  No 
Selling Shareholder has advised the Company that it anticipates paying any 
consideration, other than usual and customary broker's commissions, in 
connection with sales of the Common Stock.  The Selling Shareholders are acting 
independently of the Company in making decisions with respect to the timing, 
manner and size of each sale.  

DESCRIPTION OF COMMON STOCK

The authorized capital stock of the Company consists of 25,000,000 shares of 
Common Stock, $0.01 par value per share.  All of the issued and outstanding 
stock of the Company is fully paid and nonassessable.  Holders of Common Stock 
are entitled to receive dividends, when and if declared by the Board of 
Directors, out of funds legally available therefore and to share ratably in the 
net assets of the Company upon liquidation.  Holders of Common Stock do not have
preemptive rights to subscribe for additional shares, nor are there any 
redemption or sinking fund provisions associated with the Common Stock.  There 
are currently 8,620,051 shares of Common Stock outstanding owned by 
approximately 3,000 persons and/or entities.

Holders of Common Stock are entitled to one vote per share on all matters 
requiring a vote of the shareholders.  Since the Common Stock does not have 
cumulative voting rights in electing directors, the holders of more than a 
majority of the outstanding shares of Common Stock voting for the election of 
directors can elect all of the directors whose terms expire that year, if they 
so choose.

LEGAL MATTERS
Certain legal matters with respect to the legality of the securities offered 
hereby and the organization and existence of the Company have been passed upon 
for the Company by Parcel, Mauro, Hultin & Spaanstra, P.C., 1801 California 
Street, Suite 3600, Denver, Colorado  80202.

Item 15.  Indemnification of Directors and Officers.

	Article 7-109 of the Colorado Business Corporation Act authorizes the 
indemnification of directors and officers against liability incurred by reason 
of being a director or officer and against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement and reasonably incurred in 
connection with any action seeking to establish such liability, in the case of 
third-party claims, if the officer or director acted in good faith and in a 
manner he reasonably believed to be in or not opposed to the best interests of 
the corporation, and in the case of actions by or in the right of the 
corporation, if the officer or director acted in good faith and in a manner he 
reasonably believed to be in or not opposed to the best interests of the 
corporation and if such officer or director shall not have been adjudged liable 
to the corporation, unless a court otherwise determines.  Indemnification is 
also authorized with respect to any criminal action or proceeding where the 
officer or director also had no reasonable cause to believe his conduct was 
unlawful.

	The above discussion of the Colorado Business Corporation Act is only a 
summary and is qualified in its entirety by the full text of the foregoing.

Article VIII of the Registrant's Bylaws provides as follows:

	Each past, present and future director and officer of the corporation shall 
be indemnified by the corporation against all expenses, penalties, and 
liabilities, including attorneys' fees, reasonably incurred by or imposed upon 
him in connection with any actual or threatened claim, demand, action or 
proceeding, whether civil or criminal, or in connection with any settlement 
thereof, to which he may be made a party, or in which he may become involved, by
reason of his being or having been a director or officer of the corporation, 
whether or not he is a director or officer at the time such expenses, penalties 
or liabilities are incurred, except in cases where he shall be finally adjudged 
in such action or proceeding to be liable for willful misconduct in the 
performance of his duties as such director or officer.  The right of 
indemnification herein provided shall be in addition to, and not exclusive of, 
all other rights to which such director or officer may be entitled and the right
of indemnification herein provided shall inure to the benefit of the personal 
representatives of deceased directors and officers.

Item 17.  Undertakings.

	The undersigned registrant hereby undertakes:
	(1)  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.
	(2)  That, for the purposes of determining any liability under the 
Securities Act of 1933 (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.
	(3)  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.
	(4)  That, for purposes of determining liability under the Act, each filing 
of the registrant's annual report pursuant to section 13(a) or section 15(d) of 
the Securities Exchange Act of 1934 (and where applicable, each filing of an 
employee benefit plan's annual report pursuant to section 15(d) of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement 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.
	(5)  That, 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 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 securities being 
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate 
jurisdiction the question whether such indemnification by it is against public 
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

SIGNATURES

	Pursuant to the requirements of the Securities Act of 1933, as amended, the 
Registrant hereby certifies that it has reasonable grounds to believe that it 
meets all of the requirements for filing on Form S-3 and has duly caused this 
Registration Statement and any amendment thereto to be signed on its behalf by 
the undersigned, thereunto duly authorized, in the City of Golden, State of 
Colorado on April 18, 1997.

Re:	Registration Statement on Form S-3
	Covering the Registration of 3,036,354
	Common Shares of Earth Sciences, Inc.

Gentlemen and Ladies:

	We have acted as counsel for Earth Sciences, Inc., a Colorado corporation 
(the "Company"), in connection with the registration for sale of 3,036,354 
shares of the Company's Common Stock (the "Securities") in accordance with the 
registration provisions of the Securities Act of 1933, as amended.

	In such capacity we have examined, among other documents, the Articles of 
Incorporation and By Laws of the Company, records of corporate proceedings,  the
Registration Statement on Form S-3 filed by the Company with the Securities and 
Exchange Commission on or about April  , 1997, (as may be further amended from 
time to time, the "Registration Statement"), covering the registration of the 
Securities.  We have also made such other investigations and reviewed such other
documents as we have deemed necessary in order to express the opinions set forth
below.

	Based upon the foregoing and upon such further examinations as we have 
deemed relevant and necessary, we are of the opinion that:

	1.	The Company is a corporation duly organized and validly existing under 
the laws of the State of Colorado.

	2.	The Securities have been legally and validly authorized under the 
Company's Articles of Incorporation, as amended, and constitute (or will 
constitute upon due exercise of the options or convertible debentures as 
described in the Registration Statement) duly and validly issued and outstanding
and fully paid and nonassessable shares of the Company.
