Warm Spring
Warm Spring in Union County is a roadside spring about seven miles from the town of Union and a few steps from Hill Street. The water is warm, in the mid eighties, too cool for a real soak and fine for a wade. Ownership and access are blank on the record. There is a photo on file.
Hill Street runs within fifty-some feet, so reaching the spring is a matter of pulling over. Elevation is under three thousand feet. The valley here gets about thirty inches of precipitation and a little over four feet of snow in a typical winter. No land manager is recorded. Moss Springs Campground is the closest camping listed, a bit over six miles off.
Winter rates best. Hill Street is the named street here, and with no land owner on file, ownership is a question to settle before you treat the place as public. Moss Springs Campground sits six miles away if you want to camp. No water chemistry has been done. The water is warm and nothing close to hot.

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.
