Half Mountain is along the crest of Long's Peak/Glacier Gorge's Northwest ridge. This subarea includes: Astro Tower, Darkberry Buttress, Astro Slab (aka The Chronic Buttress), and Astro Monk.

This subarea area was added by suggestion/request.

Getting There 

Gillett's 2001 RMNP Climber's Guide ascent from Mill's Lake. It may be considered the worst approach hike ever. Per Scott Kimball, the bushwack angling around slabs and talus then through Krummholz forests took over three hours from the lake.

Finish on a steep and blocky 5.8 rib to the summit....[more]   Browse More Classics in Colorado
