Cottonwood Hot Springs comes out hot, near the upper end of hot, too much for a straight soak at the source. It is in Chaffee County, Colorado, about five miles from Buena Vista, close to eighty-seven hundred feet up. Public access and land owner are missing from the record. A USGS site exists, and a 1976 sample showed alkaline water carrying iron.

Location

An unnamed road runs past within a couple hundred feet; this one is a pull-over. High country with real winter, five-plus feet of snow, a yearly mean below forty. Precipitation is moderate across the year. The file has nothing on land unit or designation. Study the climate chart before any cold-season trip.

Winter gets the nod in the record for best months. Roadside. Collegiate Peaks campground is about five miles away by the file. Fee: not recorded. It is hot enough to hurt; test before contact and do not sit in the outflow without checking it first. Access status is blank, so establish who owns the ground.

153 milliwatts per square meter of heat flow

That's about 2½ times the US average of 65. It's higher than at 94% 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.
