Astoria Mineral Hot Springs
Astoria Mineral Hot Springs flows at 99°F from a roadside location 75.9 meters from West Johnny Counts Road in Teton County, Wyoming. The spring emerges 57.3 degrees warmer than the 41.7°F annual average air temperature at 5,868 feet elevation within Teton National Forest. Water chemistry shows high sulfate (540 mg/L) and significant calcium (180 mg/L), magnesium (46 mg/L), and chloride (88 mg/L).
Located in Snake River Canyon southwest of Jackson at 5,868 feet elevation, the spring sits where the Snake River has cut a dramatic gorge through volcanic and sedimentary rocks. The canyon walls rise steeply above the river corridor, with sagebrush and juniper covering lower slopes and Douglas fir and lodgepole pine occupying north-facing aspects. Annual snowfall reaches 140.8 inches while precipitation totals 27.9 inches in this high-elevation canyon environment. The Snake River flows nearby, providing world-class trout fishing and whitewater rafting. US Forest Service lands surround the spring with protection status allowing extractive uses.
Access from spring through fall; winter brings extreme cold, heavy snow, and avalanche danger in the canyon. The 99°F water provides genuine warmth but requires caution regarding mineral content and flow conditions. Station Creek Campground 11.6 km away offers two group sites for up to 40 people each near a Snake River boat ramp. The spring sits 27 miles southwest of Jackson along the scenic canyon drive. Combine with world-class fly fishing for cutthroat, rainbow, and brown trout or whitewater rafting expeditions.
The Astoria name likely references early mining or homesteading activity in Snake River Canyon, though specific origin documentation remains scarce. The spring's high mineral content and convenient location near the river probably attracted ranchers and travelers using the canyon route between Jackson and Hoback Junction. Commercial development history remains unclear, though the spring appears on forest service maps as an established feature. Current status shows continued public access on forest land.
The water at Astoria Mineral Hot Springs is slightly alkaline (pH 7.3). 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).
