With significant assistance from the climbing community, the Town of Estes Park, Colorado purchased and permanently protected a portion of Prospect Mountain, home to the iconic granite climbing on the Thumb and Needle spires. These public lands will now be preserved in perpetuity as Thumb Open Space.

First climbed by the legendary Tom Hornbein in the late 1940s, these two features were later used by Tommy Caldwell as a training ground. The property now offers nearly 50 routes from 5.0 all the way up to 5.13, as well as high-quality bouldering. The area is also known for its great hiking, trail running, and dog walking—with Longs Peak, Mount Meeker, and Twin Sisters in view from nearly the entire trail.
