Wilson Lake Warm Spring
Wilson Lake Warm Spring surfaces at 86°F at 6,134 feet elevation in Caribou County, providing water 44.6 degrees above the local ambient air temperature. A 227-meter walk from Government Dam Road leads to the spring. No USGS chemical analysis is on record, leaving its geochemistry undocumented in public databases.
The spring sits in the high terrain of southeastern Idaho near the town of Soda Springs, a region defined by broad sage-covered valleys, volcanic remnants, and the upper Bear River watershed. Annual snowfall averages nearly 88 inches at this elevation, and mean annual air temperature is just 41.4°F, creating harsh winters. The Blackfoot River and its tributaries drain the surrounding landscape. Aspen groves and mixed grasslands occupy the mid-elevation slopes between the valley floors and timbered ridges above.
Soda Springs, the nearest town, sits in a geologically active zone known for numerous mineral springs and the world's only captive geyser, controlled since 1937. Wilson Lake and its associated dam infrastructure give the spring its name. The broader Caribou County area saw early development tied to Oregon Trail emigration and later phosphate mining. Specific historical records for this particular warm spring are limited.
Sage Hen Flats Campground on the Blackfoot River, about 10.7 km away, operates first-come-first-served with four basic sites managed by the BLM. It has vault toilets but no water or trash service, so pack everything in and out. The 86°F water temperature is comfortable for soaking in cooler months. Snow and cold restrict practical access from November through May. Combine a visit with a stop at the Soda Springs Geyser in town.
