Primitive & Unconfined Recreation:
Primitive and unconfined recreation opportunities do exist mainly in the rimrock portion of the WSA. These include wildlife observation and photography, rock hounding, horseback riding, hiking and backpacking, and observation and photography of the many geologic eco-sites within the rimrock area.

Features: 
The South Pinnacles WSA encompasses 10,800 acres, including 26 acres of split estate land. The study area contains mostly flat topography, with an exposure of broken rimrock and ridges running west to east. Rough, rocky crags and unusual escarpments are prominent in this area. Greasewood communities occupy the draws while big sagebrush and Nuttall’s saltbrush dominate the open areas.

Naturalness:
The South Pinnacles WSA is essentially natural in character. It contains mostly flat topography, with an exposure of broken rimrocks and ridges. Rough rocky crags and unusual escarpments are prominent in this rimrock area.

There are some seismic trails, two-track trails and one abandoned drill site, but these are relatively faint and obscure. Overall, most of the WSA shows very few signs of human activity and the intrusions do not detract from the natural character of the area.

Solitude:
The rimrock area of the South Pinnacles WSA provides outstanding opportunity for solitude. The numerous pockets and small draws provide an excellent opportunity to avoid the sights and sounds of other people. Other opportunities are limited due to the boundary roads.
