[2] Located on a broad plateau rising immediately south of Walker Pass in the southern Sierra Nevada, are the Scodie Mountains.

The wilderness encompasses the eroded hills, canyons and alluvial fans-bajadas of the Scodie Mountains Unit within the Sequoia National Forest—the southern extremity of the Sierra Nevada.

A unique mixing of several different species of plants and animals occurs within the transition zone between the Mojave Desert and Sierra Nevada.

A rare and endemic wildflower, the Walker Pass milkvetch (Astragalus ertterae) of the pea family, grows within the Pinyon-Juniper woodland.

The Walker Pass milkvetch was first described in 1987 from a collection made in 1982 along a newly constructed section of the Pacific Crest Trail.

Activities in the wilderness include day-hiking, backpacking, pinyon nut gathering, and nature photography.
