Item 5.  Other Events and Regulation FD Disclosure.

     On January 27, 2003, St. Mary Land & Exploration Company learned that
certain clerical errors had occurred in computing the effect of natural gas
commodity price changes on the mark-to-market accrued derivative balance sheet
asset and liability resulting from its natural gas hedging positions together
with the related deferred income tax and accumulated other comprehensive income
balance sheet amounts, along with the footnotes thereon, set forth in St. Mary's
consolidated balance sheets included in its quarterly reports on Form 10-Q for
the quarterly periods ended March 31, 2002, June 30, 2002 and September 30,
2002.

     Such errors did not have any effect on the consolidated statements of
operations or cash flows for any of the periods included in such reports, and
St. Mary has determined that the effects of the errors were not material to any
of the affected balance sheets or to the financial statements taken as a whole.
In addition, the disclosures regarding the details of the underlying hedge
contracts, including volumes, average fixed prices and duration, as set forth in
the Management's Discussion and Analysis of Financial Condition and Results of
Operations section in each of the 2002 Form 10-Qs and in press releases issued
by St. Mary during that period, enabled the computation of accurate amounts with
respect to the above described balance sheet items.

     With respect to St. Mary's consolidated balance sheet as of September 30,
2002 included in its Quarterly Report on Form 10-Q for the quarterly period
ended September 30, 2002, had the clerical errors not been made, the accrued
derivative asset of $5,973,000 would have been reduced to $0, which reduction
would have been partially offset by an increase in the deferred tax asset from
$0 to $4,241,000, with a net reduction in total current assets of $1,732,000
from $105,789,000 to $104,057,000. In addition, the accrued derivative liability
would have been increased from $0 to $7,593,000, which net of an insignificant
reduction in the deferred tax liability would have resulted in an increase in
total current liabilities of $6,614,000 from $42,581,000 to $49,195,000. Also,
accumulated other comprehensive income, a component of stockholders' equity,
would have been reduced by $9,109,000 from $2,015,000 to a loss of $7,094,000
thereby reducing total stockholders equity from $302,374,000 to $293,265,000.
Further, a disclosure was made in the notes to consolidated financial statements
that based on current prices St. Mary expected that $2,399,000 of the after tax
gain amount included in accumulated other comprehensive income will be included
in earnings during the next 12 months. Such amount should have been an expected
loss of approximately $6 million based on commodity prices at that time. Such
mark-to-market commodity hedging position gains and losses change daily with
daily changes in commodity prices.

     The Company issued a press release dated January 28, 2003 announcing the
clerical errors and the filing of this report. Such press release is furnished
as part of this report as Exhibit 99.1.
