Climbing the Southwest Slopes

From Telluride, Colorado, take Highway 145 south and turn onto Silver Pick Road. Follow the rough road to Navajo Lake trailhead. High clearance 4WD recommended. Loose rock and significant exposure on the upper mountain require advanced route-finding skills. The ridge to the summit involves Class 4 terrain with serious drop-offs. Often combined with El Diente via the famous traverse, one of Colorado's most challenging routes. Helmets essential. Start very early (2-3am) for the long day. Only for experienced mountaineers comfortable with serious exposure. One of Colorado's most demanding 14ers.
