Backpacking camp
Big Pine North Fork — Inyo National Forest, California
Third Lake sits directly beneath the steep eastern face of Temple Crag, creating one of the most dramatic alpine settings in the Big Pine Lakes basin. Glacially influenced water gives the lake a distinctive blue-green color, while its shoreline is bordered by granite, moraine, boulders, scattered pines, and small flatter areas near the northwest and eastern ends. Temple Crag dominates the view above the lake, while the surrounding ridges provide glimpses toward the higher Palisade terrain. The lake lies near the junction of routes continuing toward Sam Mack Meadow and Palisade Glacier and those leading toward the higher numbered lakes, making the area a natural crossroads for exploring the upper basin
Water planning
Third Lake and Unnamed mapped stream or river are mapped at or near the camp-area marker. This is map evidence, not a real-time flow report.
Natural water is not verified potable. Filter and disinfect it or boil it according to the linked land-manager guidance before drinking.
Third Lake is a mapped waterbody; USGS does not classify it here as seasonal or year-round. Confirm current level, access, and quality. Unnamed mapped stream or river is classified as perennial in USGS hydrography, but current flow still must be confirmed.
Seasonal access
No recurring date-based closure of Third Lake is published. The source-connected approach conditions below and temporary emergency orders still control access.
Source-connected approach: Big Pine Creek North Fork Trailhead. High Sierra approaches can be snowbound well into summer, and several roads, shuttles, and remote spurs operate only seasonally. Desert and foothill entries may remain physically reachable in winter but can become unsafe in storms, heat, or after washouts.
Check the exact county, highway, Forest Service road, gate, and shuttle status immediately before departure; a wilderness permit does not guarantee vehicle access.
