Project Information: Volunteers will help Forest Service staff repair several eroding sections of the route and rehabilitate other damaged sections. For two days we will car camp at Whitney Portal, hiking about one hour to the work site. We will move camp to Lower Boy Scout Lake to do work near the lake outlet, and then on to Upper Boy Scout lake.

Area Description: The Mountaineer's Route provides access to some of the legendary mountain climbing terrain in the Sierra Nevada. Beginning as a rough trail near Whitney Portal, the route climbs steeply up the North Fork of Lone Pine Creek drainage. During the trip, volunteers will ascend through conifer forest, reaching an alpine setting of glacial lakes among the peaks of the Mt. Whitney area. In their free time, depending on skills and energy, participants can climb Mt. Whitney or explore several lakes in the drainage. Some scrambling on steep and rugged terrain is required to get to the trip's wilderness campsites.
Climate Information: Weather conditions will vary from hot mid-day temperatures (80s) on south-facing slopes, to chilly nights (40s) at the higher elevations.

Travel Information: No airport pickup is available. Closest airport is Reno/Tahoe in Reno, NV.
