Lodgepole (Big Warm) Springs
Lodgepole Springs, also known as Big Warm Springs, discharges at 79°F on the Fort Belknap Reservation at 3,360 feet elevation in Blaine County, Montana. The water is among the most mineralized in the area, with 1,100 mg/L sulfate, 270 mg/L calcium, and 96 mg/L magnesium. A short walk of 310 meters from the nearest road is required. Public access is unknown.
The spring rises on the northern edge of the Little Rocky Mountains, an isolated range surrounded by the vast grasslands of north-central Montana's high plains. At 3,360 feet, lodgepole pine — likely the source of the primary name — and ponderosa pine dot the rocky slopes, giving way to open prairie within a short distance. The terrain is rolling, with shallow coulees draining north toward the Milk River basin. Annual precipitation averages 19 inches, with 42 inches of snow. Winds are persistent across the exposed plains.
Tribal authorization from the Fort Belknap Indian Community is required before visiting — do not approach without permission. If access is granted, the 310-meter walk crosses unimproved terrain. At 79°F, the water is warm but not hot, suitable for wading in summer conditions only. Camp Creek Campground is first-come, first-served. Zortman, the nearest town with services, has a store and fuel. Carry drinking water; the high sulfate content makes the spring water unpalatable.
The name Lodgepole references the pine species found at the site, while the alternate name Big Warm reflects the thermal discharge relative to other nearby springs. The spring lies within the Fort Belknap Reservation, homeland of the Aaniiih and Nakoda peoples. Thermal features in the Little Rockies held significance for Indigenous communities long before Euro-American exploration. The site remains undeveloped, with no commercial infrastructure. Camp Creek Campground, 9.1 km away, provides the closest public camping.
The water at Lodgepole (Big Warm) Springs contains 1670 mg/L total dissolved solids. It is notably rich in calcium (may support bone density and joint health), magnesium (known for muscle relaxation and stress relief), and sulfate (traditionally used for skin conditions and inflammation).
