## About Johnson Springs

Johnson Springs is a hot spring in Lincoln County, Wyoming, seven miles from Afton. At 115 degrees on the record it is hotter than a bath and would need cooling or caution before anyone sat in it. Ownership is not on file and neither is public access. The spring is roadside, within a few hundred feet of a road, name not given.

Around six thousand feet, with nine feet or so of snow in a winter and a couple feet of precipitation across the year. No land unit, no owner. Camping on record: Stump Creek Guard Station, under five miles.

Hot enough to hurt if you jump in, so test first and find the cooler edge. With no access status on record, the landowner question comes first. Winter is the listed season. The chemistry is from a 1971 sample, slightly acidic. No fee on file.
