Head Spring
Head Spring flows at 70°F from high country straddling the Utah-Idaho border, emerging just 20 meters from road access at 6,620 feet elevation in Cassia County. Recent USGS measurements documented 21.1°C with pH 8.0 and relatively low total dissolved solids of 240 mg/L, while chemistry shows 54 mg/L calcium, 8.3 mg/L magnesium, and 20 mg/L sodium balanced by 9 mg/L sulfate and 36 mg/L chloride. The spring runs 26 degrees above ambient in mountain terrain receiving 14 inches of precipitation and 43 inches of snow.
The spring occupies mountain terrain at 6,620 feet elevation in the Raft River Mountains, where ponderosa pine, aspen, and Douglas-fir replace lower elevation sagebrush and juniper. This high-elevation setting experiences cooler temperatures averaging 44°F annually, with the spring emerging near drainage systems feeding into the Snake River basin. Surrounding landscape features forested slopes, mountain meadows, and geological formations characteristic of Basin and Range fault-block mountains, with the spring's low mineralization reflecting relatively shallow circulation through volcanic and sedimentary rocks.
The simple name Head Spring suggests location at the headwaters of a drainage, with the area utilized by Shoshone and Bannock peoples before Euro-American settlement. The border region developed primarily for ranching and timber rather than spring-related activities, with the remote terrain limiting settlement even during homesteading periods. The spring remains undeveloped today in mountain country managed for multiple uses including grazing, recreation, and wildlife habitat.
The roadside location at 6,620 feet is typically accessible June through October, with winter snow closing mountain roads. Clear Creek Campground lies 31 km away, offering non-fee camping and access to trails popular with horseback riders and hikers. Bring warm clothing even in summer, as nights cool substantially at this elevation. The spring's moderate temperature and low mineralization suggest good water quality, though visitors should assess current conditions.
