Grassy Mountain Overview

Grassy Mountain is located 2.3 east of the centennial thirteener 13811. Grassy Mountain is the highest of three Grassy Mountain’s in Colorado, hence the A. Grassy is the 768th highest peak in Colorado and the 131st highest twelver in the state. Grassy Mountain is rarely climbed. A new summit register left by Jennifer Roach on June 14, 2005 was signed by only one other party prior to July 29, 2007. When Grassy is climbed, it is usually by its west ridge. Grassy Mountain’s west ridge can be accessed many ways: Williams Creek Trailhead, Silver-Grizzly Gulch Trailhead, Lake San Cristobal Trailhead and Alpine Gulch Trailhead. Starting at the Alpine Gulch Trailhead appears to be the easiest approach and is described below.
