Location
The springs are located at the Middle Fork of the Salmon River in the state of Idaho.[2] This area was used by the Shoshone and Nez Perce prior to the arrival of fur trappers, miners, and later early homesteaders.[3] The springs are located at an elevation of 4,357 feet (1,328 m).[1]
Water profile and geography
The spring water emerges from the bedrock 30 feet above the river at a temperature of 149 °F (65 °C).[4][5] The springs have five rock pools, and part of the hot spring water cools to 102° as it cascades off a rock to create a primitive hot shower.[6] Mineral content of the water includes calcium, potassium, magnesium, sulfate, with a pH of 8.7.[7]
