Steamboat Hot Spring emerges near Soda Springs in Caribou County at 88 degrees Fahrenheit, one of many thermal features dotting this geologically restless corner of southeastern Idaho. Its mineral load of 1,450 mg/L total dissolved solids includes unusually high calcium and magnesium concentrations.

Location
19 miles from Soda Springs, ID

A short walk of about 365 feet from the road reaches the spring at 5,723 feet elevation. The water carries 261 mg/L of calcium and 182 mg/L of magnesium along with 250 micrograms per liter of iron, which stains the outflow channels rust-orange. At 46 degrees above the 41.9-degree ambient air, the thermal contrast is moderate. The Soda Springs area sits in a high valley that receives 80 inches of snow annually, and the spring's mineral deposits build visible travertine formations around its emergence point.

The spring requires a short walk from the nearest road and sits near several other thermal and mineral features worth exploring in the Soda Springs area. The 88-degree temperature is warm but below typical soaking comfort. Iron content may stain clothing and skin. Eight Mile Guard Station, a rentable historic cabin, sits about 9 miles away. The town of Soda Springs has services and is worth visiting for its collection of mineral springs.

History of Steamboat Hot Spring

The Soda Springs region sits where the Blackfoot and Bear River lava fields meet ancient sedimentary formations, creating conditions for extensive mineral dissolution. Steamboat Hot Spring draws from the same carbonated aquifer system that produces the town's famous geyser and thousands of other mineral springs. The high calcium-magnesium chemistry indicates prolonged contact with limestone and dolomite formations rather than the granitic sources typical of central Idaho's thermal features.
