Elk Creek Hot Spring
Elk Creek Hot Spring surfaces at 126 degrees F in the high sagebrush country of Camas County, running 84 degrees above ambient air temperature at 5,660 feet elevation. A short 350-foot walk from the nearest road leads to the spring, which carries 302 mg/L of total dissolved solids and a pH of 9.0, indicating deep geothermal circulation through alkaline rock.
The spring emerges where Elk Creek cuts through rolling hills covered in sagebrush and bunchgrass, with scattered stands of aspen and Douglas fir at higher elevations nearby. The terrain feels vast and open, characteristic of central Idaho's high plateau country between the Soldier Mountains and the Smoky Range. Mineral deposits color the ground near the source, and the warm outflow supports a strip of green vegetation that stands out against the dry surroundings. Wind is a near-constant presence at this elevation.
The nearest developed campground is Bowns Campground, 18 miles away along Big Smoky Creek, with 10 free first-come sites, fire rings, and seasonal drinking water. The 350-foot walk to the spring is on open terrain. At 126 degrees F, the source water is too hot for direct contact without mixing. Annual snowfall averages over 7 feet, limiting reliable access to roughly June through October.
Elk Creek sits along one of several northwest-trending fault zones in the region that tap deep thermal reservoirs. The water chemistry, with 92 mg/L sodium, 42 mg/L sulfate, and negligible magnesium at 0.01 mg/L, points to prolonged contact with granitic basement rock at depth. The USGS has measured the source at 54 degrees C. Camas County takes its name from the camas lily bulbs that Shoshone-Bannock people historically harvested from the nearby prairie, a food source that shaped regional settlement patterns.
The water at Elk Creek Hot Spring is alkaline (pH 9.0) with 302 mg/L total dissolved solids.
