  • Description 

    This large, obscure formation is approximately 1/2 mile west of Seal Rock and 3/4 mile south of the Sacred Cliffs. It is not listed in the current Flatirons guidebook. The approach is difficult, and the rock quality is extremely poor. But if you have a youthful spirit of adventure, want to explore something unusual, and are interested in climbing an expanding chimney, then it's definitely worth a visit.

    Getting There 

    To get there: follow the Mesa trail to the junction with Bear Canyon. Head West into Bear Canyon for about 1/2 mile. You will have walked past Overhang Rock, Poot Ridge, and the Sanctuary formations. Unknown Rock is the next large formation on the south side of Bear Canyon. An off-trail permit and bushwhacking are required to reach the base.

    The first 50' is the crux, climbing through licheny and rotten rock. From there, move up and left past a large tree to get on the main slab.The main slab is heavily featured and consistently steep. Keep going up until you are on the ridge, the climbing is the same for 50' horizontal in either direction. This was a wonderful solo!...[more]   Browse More Classics in Colorado
