Browns Grotto Warm Spring, eight miles or so from Salida in Chaffee County, Colorado, is tepid, room temperature at best, at roughly seventy-four hundred feet. Access and ownership are absent from the file, so who controls it is the open question. A 1976 USGS sample gives alkaline water with iron and sodium in it.

Location

Something under two hundred yards separates it from the closest road, which the record does not name, so finish on foot. High country; winters drop a good deal of snow and the yearly average sits in the low forties. Rain is modest. Land unit and designation: nothing given, so public status is unverified here.

Midwinter is what the record lists as the season, though for water this cool the season is more about getting there than the soak. Short walk. Angel of Shavano Group campground, a little under nine miles away, is the one listed, and the name suggests group sites. Fees: nothing recorded. The chemistry is old, 1976. Access is not on file; confirm before you go.

Heat Below
172 milliwatts per square meter of heat flow

That's about 2½ times the US average of 65. It's higher than at 97% 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.
