Apex Warm Spring
Apex Warm Spring emerges at 77°F in Beaverhead County, Montana, at 5,255 feet elevation near Dillon. The spring sits 337 feet from School House Road, requiring a short walk. No recent USGS chemistry or pH data are available, leaving the water's mineral profile undocumented beyond temperature. The water runs 35 degrees above the local 42°F annual average.
The spring surfaces in the semi-arid foothills of southwestern Montana's Pioneer and Beaverhead mountain country. Sagebrush and bunchgrass dominate the rolling terrain at this elevation, with scattered junipers on drier slopes and cottonwoods along creek bottoms. Annual precipitation is low at 16.4 inches, and snowfall averages 51 inches. The Beaverhead River valley lies nearby, and the landscape transitions from broad ranch valleys to timbered mountain slopes within a few miles.
Beaverhead County was one of Montana's original nine counties, established in 1865 during the gold rush era. The spring's name suggests a geographic or survey marker designation rather than a personal name. Dillon, the county seat, grew as a ranching and railroad town in the 1880s. Historical records for this particular spring are limited, and no commercial development has been documented.
Visit from late spring through early fall for reliable road conditions. The 337-foot walk to the spring is across open rangeland. Birch Creek Cabin, a historic log cabin with electricity located 13 km away, is reservable and typically accessible by passenger car in summer. Dillon provides full services including gas, food, and lodging along Interstate 15. Bring water, as the area is dry.
