White Mountain Petroglyphs | Rock Springs

The White Mountain Petroglyphs are a collection of ancient rock carvings located in the high desert plains west of Rock Springs, Wyoming.

This site preserves a significant concentration of prehistoric rock art within a rugged, arid landscape.

Visual Characteristics

The petroglyphs are etched into dark desert varnish on sandstone formations. The carvings depict a variety of figures including humanoids, animals (such as bighorn sheep and bison), and geometric shapes. The sandstone itself is predominantly tan to reddish-brown, with varying degrees of erosion.

Location & Access Logistics

The White Mountain Petroglyphs are situated approximately 25 miles west of Rock Springs, Wyoming. Access is via Interstate 80 West to Exit 135 (Artesia Drive). Turn north onto County Road 17 (also known as White Mountain Road). Continue on County Road 17 for approximately 15 miles. A sign for the petroglyph site will indicate a turn onto a graded dirt road. This dirt road is approximately 5 miles long and is generally passable by standard vehicles in dry conditions. During wet weather, high-clearance or 4WD vehicles may be necessary. Parking is available at the trailhead.

Historical & Ecological Origin

The petroglyphs are attributed to Native American cultures that inhabited the region for thousands of years, with dating estimates ranging from 3,000 to 10,000 years old. The exact purpose of the carvings is not definitively known but is believed to include spiritual, ceremonial, or communicative functions. The geological origin of the sandstone formations is part of the larger sedimentary layers of the Green River Formation.
