Pagosa Springs sits practically in town, a mile or so from the center of Pagosa Springs in Archuleta County. OpenStreetMap calls this particular source The Mother Spring. The water rises hot, well past soaking temperature at the outlet, so what comes up needs cooling before anyone gets in. Who owns the ground and what access is allowed are not recorded.

Location

Getting there is a short walk, a little over a hundred yards from the closest road. At around seven thousand feet this is mountain town country. Winter snowfall runs close to seven feet and the year is fairly wet. East Fork Campground in the San Juan National Forest is the nearest camp listed, about ten miles out.

The best stretch on record runs from December into February. At the outlet the water is hotter than skin will tolerate for any length of time, so stay out of the source flow. Who runs the place is not written down, and no fee is listed either way. Chemistry here comes from a sample taken in April 1976.

History of Pagosa Springs

Pah gosah is the Ute name, according to Wikipedia, which also puts these springs inside the San Juan Basin. Deepest geothermal hot springs known anywhere, the town itself claims. The USGS keeps the site under a number of its own, with a water sample taken in the spring of 1976.

Heat Below
100 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 47% of the springs on this site.

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.
