Very Hot Source, Use Extreme Caution

At 181°F, the source water at Hortense Hot Spring is hot enough to cause burns. Some hot springs this hot have cooler side pools or downstream areas suitable for soaking. Always test the water temperature before entering.

Hortense Hot Spring is scalding at the source. This is Chaffee County, seven miles or so from Buena Vista, and the USGS thermal point here carries a reading hot enough to cause burns on contact. There is no chemistry sample attached. Who owns the land and who may visit are not recorded. Buena Vista is the town to base from.

Location

The record puts the spring a fifth of a mile off an unnamed road, so count on a short walk. Elevation is high valley country. Snowfall runs a bit over five feet in a normal winter and the climate is fairly dry. Mount Princeton campground is the one camp listed, under three miles off.

December through February score best. Keep your hands out of the water at the source; the reading is far beyond what skin tolerates. Access and ownership are both blank, so treat this as unverified ground. Camping at Mount Princeton campground is close by. Nobody has logged water chemistry.

Heat Below
141 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 89% 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.
