Boulder Hot Springs
Water at Boulder Hot Springs arrives scalding, hot enough to blister skin, a few miles outside the town of Boulder in Jefferson County. Sitting in it straight from the source is out of the question until it cools. Ownership of the ground and the rules for using it are both missing. A 1976 USGS sample came back alkaline, carrying iron along with calcium, magnesium, sodium and sulfate.
The spring sits a tenth of a mile from the nearest road, a short walk, at valley elevation close to town. Winters bring a moderate snowpack and the year is middling for rain. Being this close to Boulder, it is an easy drive, assuming access is allowed.
Do not touch the source. At this temperature the water scalds in seconds. Any soaking would need cooled water, and nothing on file says if that exists. Winter is the listed season, and the snow is manageable. Sheepshead Picnic Area is the closest camp, around eighteen miles out. Access is not recorded, so confirm before visiting.
The water at Boulder Hot Springs is alkaline (pH 8.8).
