Elevation7800 ft above sea level

Natural Features and SceneryPine forest surrounds the site, with obsidian deposits scattered across the volcanic landscape. Deadman Creek runs through the area, and the elevation puts you in the eastern Sierra's transition zone between dry high desert and alpine terrain. The geology here reflects ancient eruptions and glacial carving: glassy obsidian chunks, granite outcrops, and creek corridors lined with Jeffrey pines. Wildlife includes black bears (hence the required bear lockers), mule deer, and the occasional mountain lion sign. The forest canopy provides decent shade but opens enough for views of the surrounding ridges.

Lodging & AccommodationsNo hotel-style lodging available on-site, as this is a primitive group campground.

Programs & ActivitiesNo cultural or educational programs are mentioned.
