     shareholder rights plan adopted on July 15, 1999, as amended, that are
     deemed to be delivered with each share of common stock issued by the
     registrant and currently are not separately transferable apart from the
     common stock.
(2)  Solely for the purpose of computing the registration fee in accordance with
     Rule 457(h) under the Securities Act, the price shown is based upon the
     price of $27.07 per share, which is the average of the high and low
     selling prices for the registrant's common stock as reported on the New
     York Stock Exchange on June 20, 2003.
(3)  Calculated under Section 6(b) of the Securities Act as .0000809 of
     $35,191,000.


         This registration statement relates to the previously filed
registration statements discussed below and is being filed under General
Instruction E. of Form S-8 in order to register additional shares of the same
class as other securities for which registration statements filed on this form
relating to the same employee benefit plans are effective.

         On June 25, 1997, the registrant filed a registration statement on Form
S-8 (File No. 333-30055) to register 754,614 shares of common stock, which
included 700,000 shares of common stock issuable under the St. Mary Land &
Exploration Company Stock Option Plan and the St. Mary Land & Exploration
Company Incentive Stock Option Plan (the "Plans"). On April 21, 2000, the
registrant filed a registration statement on Form S-8 (File No. 333-35352) to
register an additional 950,000 shares of common stock issuable under the Plans.
Under Rule 416, those registration statements are deemed to cover an additional
1,650,000 shares of common stock, or a total of 3,300,000 shares of common
stock, as a result of a two shares-for-one share forward stock split effected in
the form of a stock dividend distributed in September 2000. On May 22, 2002, the
registrant filed a registration statement on Form S-8 (File No. 333-88780) to
register an additional 1,000,000 shares of common stock issuable under the
Plans. The contents of the above registration statements are incorporated by
reference into this registration statement. The registrant is now filing this
separate registration statement to register an additional 1,300,000 shares of
common stock which as a result of amendments to the Plans may be issued
thereunder.

                  --------------------------------------------------------------
                  Issuable Under Stock Option Plans
                  ---------------------------------

Ladies and Gentlemen:

         We have acted as counsel to St. Mary Land & Exploration Company, a
Delaware corporation ("St. Mary"), in connection with the filing of a
Registration Statement on Form S-8 (the "Registration Statement") to register
under the Securities Act of 1933, as amended, an additional 1,300,000 shares of
St. Mary common stock, par value $.01 per share (the "Shares"), issuable from
time to time upon the exercise of options ("Options") granted under the St. Mary
Land & Exploration Company Stock Option Plan, as amended, and the St. Mary
Land & Exploration Company Incentive Stock Option Plan, as amended
(collectively, the "Plans").

         In that connection, we have examined, and relied upon the accuracy of
factual matters contained therein, the Plans and originals and copies, certified
or otherwise identified to our satisfaction, of such other agreements,
documents, corporate records and instruments as we have deemed necessary for the
purposes of the opinion expressed below. In giving this opinion, we are assuming
the authenticity of all instruments presented to us as originals, the conformity
with the originals of all instruments presented to us as copies and the
genuineness of all signatures.

         Based upon the foregoing, we are of the opinion that the Shares, when
issued upon exercise of the Options granted under the Plans and upon payment of
the option exercise price in accordance with the terms of the Plans, will be
legally issued, fully paid and nonassessable.

         This opinion is limited to the matters expressly stated herein. No
implied opinion may be inferred to extend this opinion beyond the matters
expressly stated herein. We do not undertake to advise you of any changes in the
opinion expressed herein resulting from changes in law, changes in facts or any
other matters that might occur or be brought to our attention after the date
hereof.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                  Very truly yours,

                                  /s/ BALLARD SPAHR ANDREWS & INGERSOLL, LLP





                                                                    EXHIBIT 23.1


                          INDEPENDENT AUDITORS' CONSENT


         We consent to the incorporation by reference in this Registration
Statement of St. Mary Land & Exploration Company on Form S-8 of our report
dated February 19, 2003, appearing in the Annual Report on Form 10-K of St. Mary
Land & Exploration Company for the year ended December 31, 2002.

            INFORMATION ABOUT LACK OF CONSENT OF ARTHUR ANDERSEN LLP

         The audit report of Arthur Andersen LLP dated February 18, 2002 (the
"Audit Report") with respect to the consolidated financial statements of St.
Mary Land & Exploration Company ("St. Mary") as of December 31, 2001 and
2000 and for each of the three years in the period ended December 31, 2001
included in St. Mary's Annual Report on Form 10-K for the year ended December
31, 2002 filed with the Securities and Exchange Commission ("SEC") on March 13,
2003 (the "2002 Form 10-K") incorporated by reference in this registration
statement is a copy of the Audit Report previously issued by Arthur Andersen LLP
and included with Arthur Andersen LLP's consent in St. Mary's Annual Report on
Form 10-K for the year ended December 31, 2001 filed with the SEC on March 19,
2002 (the "2001 Form 10-K") and St. Mary's Annual Report on Form 10-K/A for the
year ended December 31, 2001 filed with the SEC on March 25, 2002 (the "2001
Form 10-K/A"). The Audit Report was not reissued by Arthur Andersen LLP for
inclusion with the 2002 Form 10-K, but a copy of the Audit Report was included
in the 2002 Form 10-K in reliance on Rule 2-02(e) of Regulation S-X promulgated
by the SEC.

         The 2002 Form 10-K is incorporated by reference in St. Mary's
previously filed Registration Statements on Form S-8 (Registration Nos.
333-30055, 333-35352 and 333-88780) (collectively, the "Registration
Statements") incorporated by reference in this registration statement. Although
St. Mary obtained the consent of Arthur Andersen LLP to the incorporation by
reference in the Registration Statements of the Audit Report included in the
2001 Form 10-K and 2001 Form 10-K/A, after reasonable efforts St. Mary has not
been able to obtain the consent of Arthur Andersen LLP to the incorporation by
reference in the Registration Statements or in this registration statement of
the Audit Report included in the 2002 Form 10-K. Therefore, in reliance on Rule
437a under the Securities Act of 1933 (the "Securities Act") St. Mary has not
filed a consent of Arthur Andersen LLP with this registration statement. As a
result, with respect to transactions in St. Mary securities pursuant to this
registration statement, investors will not be able to recover against Arthur
Andersen LLP under Section 11 of the Securities Act for any untrue statement of
a material fact contained in the financial statements audited by Arthur Andersen
LLP as indicated in the Audit Report and incorporated by reference in this
registration statement from the 2002 Form 10-K, or any omission to state a
material fact required to be stated therein. In addition, due to the significant
decline in size of Arthur Andersen LLP and their termination of operations after
having been found guilty in June 2002 of federal obstruction of justice charges
arising from the U.S. government's investigation of Enron, investors are
unlikely to be able to exercise any effective remedies against or collect
judgments from Arthur Andersen LLP.

                   CONSENT OF INDEPENDENT PETROLEUM ENGINEERS
