Little Warm Spring
Little Warm Spring discharges at 77 degrees Fahrenheit just 42 meters from Three Spear Ranch Access Road at 7,403 feet elevation. The spring runs 41 degrees above the 35.8-degree ambient temperature in terrain receiving 103 inches of annual snow.
The thermal feature sits in upper Green River valley ranchland where precipitation totals 21 inches annually. The roadside location places the spring in working private property, surrounded by irrigated hay meadows and seasonal cattle range at the interface between valley bottom and mountain slopes.
Access crosses private property requiring landowner permission. The roadside location presents no technical challenges if permission granted. Green River Lakes Lodge, 27.7 kilometers north, offers day-use and overnight rental. Winter access becomes impassable when snow closes valley roads, typically November through May.
Documentation of historical development remains sparse. The spring likely provided water for early ranching operations in this remote valley, though commercial thermal exploitation never occurred. Current status involves private land with limited historical record available.
