Greaser Petroglyph Site

The Greaser Petroglyph Site is an archaeological location in Lake County featuring ancient rock carvings created by Indigenous peoples. A basalt boulder displays etched images of animals, human figures, and geometric patterns that have remained visible across thousands of years.

The carvings were created thousands of years ago, showing a long history of human occupation in this region. The site was added to the National Register of Historic Places in 1974, officially recognizing its importance to archaeology and regional history.

The Northern Paiute people lived in this region and created the carved figures as part of their daily life and spiritual practices. The petroglyphs show how these communities used the canyon landscape, leaving behind images that reflected their world and beliefs.

The site is located about 5 miles east of Adel and is maintained by the Bureau of Land Management. Visitors should avoid touching the rock surfaces and follow protection guidelines to help preserve the ancient carvings.

The petroglyphs remain on an exposed boulder at a location where lakes once filled the surrounding landscape before drying up. Today visitors stand at the same spot where ancient peoples left their marks while experiencing a completely transformed environment.
