Geyser (Warm Spring Creek Springs)
This thermal feature produces 84-degree Fahrenheit water on Bureau of Land Management lands at 7,260 feet elevation, emerging immediately adjacent to the road in the Warm Spring Creek drainage. USGS analysis records near-neutral pH of 6.8 and 486 milligrams per liter total dissolved solids, with the 28-degree Celsius water temperature exceeding ambient air temperature by 47 degrees Fahrenheit.
The spring sits in sagebrush and grassland terrain characteristic of the upper Green River basin near Pinedale in Sublette County. The surrounding landscape features rolling hills with scattered aspen groves and willow-lined creek drainages. Elevation of 7,260 feet places the site in the transition zone between valley floor and mountain slopes, with views toward the Wind River Range to the east. Annual precipitation totals 22 inches with 107 inches of snow.
Early references describe this as a true geyser with periodic eruptions, though current behavior appears to be steady flow. The Warm Spring Creek name reflects the thermal influence in this drainage system. Homesteaders and ranchers in the Pinedale area knew of the thermal springs by the late 1800s. The site sits on public land managed by BLM's Lander Field Office under multiple-use designation allowing mineral development and grazing.
The spring is immediately roadside with no hiking required. Access roads may require high-clearance vehicle depending on season and maintenance. Visit June through October for reliable access; winter conditions close backcountry roads. Water temperature is pleasant but chemistry should be tested before prolonged contact. Green River Lakes 29 kilometers north offers developed recreation facilities and spectacular Wind River Range scenery worth combining into a longer trip.
