Butte Springs (Trego Hot Springs)
Trego Hot Springs discharges at 187 degrees Fahrenheit on Bureau of Land Management property in Pershing County, making it one of Nevada's most powerful geothermal features. Recent USGS sampling documented water at 86 degrees Celsius with alkaline pH of 8.2 and high-sodium chemistry showing 445 milligrams per liter sodium and 280 milligrams per liter chloride. The spring sits 8 meters from the nearest road, providing roadside access to thermal water flowing 132 degrees above ambient.
At 4,000 feet elevation in the Black Rock Desert, the spring emerges in the vast playa landscape that defines northwestern Nevada's most iconic wilderness. The setting represents classic Basin and Range topography where isolated mountain ranges rise from broad valleys covered in sage and desert scrub. Average annual precipitation totals just 8 inches with 15.5 inches of snow, supporting minimal vegetation in terrain where ambient temperatures average 54.9 degrees Fahrenheit. The spring location offers sweeping views across the Black Rock playa, with Barley Road providing the primary access corridor through this remote BLM district.
The name "Trego" dates to the 1910s following construction of the Western Pacific Railroad, when this location served as a station stop. Earlier names included Hot Springs, Kyles Hot Springs (documented in 1864), Butte Spring, and Butte Hot Spring, reflecting the prominent butte landform visible from the thermal area. The spring marked an important waypoint along pioneer routes crossing the Black Rock Desert, though specific development history remains scant in available records.
Visit between April and October when roads across the Black Rock Desert remain passable; winter snow and spring mud render many routes impassable. High-clearance vehicles recommended for approach roads. Water temperature of 187 degrees Fahrenheit requires extreme caution and prohibits direct bathing without cooling. Combine with visits to nearby Black Rock playa or Soldier Meadows. Carry water, fuel, and emergency supplies as services remain over 60 miles distant in Gerlach or Lovelock.
