Gannett Peak Cirque of the Towers Looking up at the Main Wall from the parking lot, the dolomite climbing extends for over a mile in length and provides excellent year-round climbing, bouldering, and camping. Just because Sinks Canyon is in Wyoming does not mean you can't climb during the winter months. Sinks Canyon has walls comprised of Big Horn Dolomite, a medium seemingly designed for climbing.
Climbs utilize pockets, edges, crimps, gastons, side-pulls, flat finger buckets and sloping rails.
