The Pilot Valley Playa is a playa and salt pan in Box Elder County, Utah and Elko County, Nevada that is a remnant of Pleistocene Lake Bonneville.

[1] Springs are located in the alluvial fans at the base of the Pilot Range, and no water flows from the Silver Island Mountains.

[citation needed] Shallow groundwater (e.g., Bettridge Creek, with threatened Lahotan cutthroat trout) along the western edge of the playa varies from fresh water to brine over a distance of about 2,000 feet.

[2] The Pilot Valley Playa gets very little precipitation, experiences extreme temperatures and high wind speeds.

[3] The playa is within the Pilot-Thousand Springs Watershed (USGS Huc 16020307), a 1,780 sq mi (4,600 km2) endorheic area.
