Test Hill overview
Test Hill
In addition to its recreational opportunities, Test Hill offers a unique glimpse into California's history. The area was once part of the ancient Lake Cahuilla, which covered much of the Salton Basin. Today, visitors can see evidence of the past in the form of fossils and shells embedded in the hill's sedimentary layers. The area also has a rich cultural history, with evidence of human habitation dating back thousands of years. Visitors can see petroglyphs and other artifacts left behind by the region's indigenous peoples. Overall, Test Hill is a must-see destination for anyone interested in California's natural and cultural history.

Responsible visitation & Leave No Trace
- Know before you go
- Check the operator's site (BLM, NPS, state agency, or private owner) for access rules, permits, and seasonal closures before driving out.
- Stay on trail
- Many points of interest sit in fragile ecosystems. Stick to marked paths to protect vegetation and prevent erosion.
- Respect wildlife
- Observe from a distance, never feed wildlife, and give nesting birds and denning mammals plenty of space.
- Pack it in, pack it out
- Take all trash, food scraps, and gear back with you. Remote sites often have no trash service.
- Leave what you find
- Don't take rocks, plants, fossils, or artifacts. Federal law protects cultural and natural resources on public land.
