>From the Backcountry Camping Guide from last year:

Old Numbers:
     (303) 586-4459, (303) 586-3565 - ext 243   --- Voice
     (303) 586-4702,                            --- Fax
     (303) 586-8506                             --- TDD

New Numbers:
     (970) 586-1242      --- Voice
                         --- Fax (unavailable?)
     (970) 586-1319      --- TDD

Note further that starting April 2, 1995 these numbers will be under
the new 970 area code.  You should be able to use both the 303 and the
970 number for 6 months, then the 303 number gets reassigned to somebody
in the Denver metro area.
