Astoria Mineral Hot Springs
Astoria Mineral Hot Springs sits just outside Hoback in Teton County, Wyoming, on Teton National Forest land. The water is body temperature, soakable without being hot, and the record lists access as open. West Johnny Counts Road passes close enough that the record calls this roadside.
The road is within a stone's throw. National forest ground, a bit under six thousand feet, with deep winters, nearly twelve feet of snow in a season, and a dryish summer. Station Creek Campground is the nearest listed, about seven miles.
Winter ranks best on the record, which with this much snow means checking whether the road is plowed. Access is open and no fee is listed. Water chemistry on file comes from a 1971 sample, so the neutral pH figure is half a century old. The temperature is gentle, no scald risk.
The USGS carries this spring as a numbered thermal site, and the only chemistry on file is that 1971 sample showing calcium, magnesium, sodium, sulfate and chloride.
Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Astoria Mineral Hot Springs.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
