A second Thermo Hot Springs entry sits in the same patch of Beaver County as the first, under twenty miles from Milford. This vent runs slightly hotter still, well past the point where water scalds, and it is listed as a USGS thermal site with no sign in the record that anyone bathes here. Land ownership and access are blank.

Location

Getting to it means leaving the road and walking something under half a mile across ground that sits around five thousand feet and sees very little rain. Snow is light in winter. The road itself has no recorded name, and no agency is listed as owning or managing the land.

Scalding water, so keep clear of the source and assume any pool fed by it is dangerous until proven otherwise. Winter months are the ones the record favors. The closest camping on file is Hanging Rock Campground, around eighteen miles off. The water sample is from 1963 and shows high dissolved solids with a mildly alkaline pH; treat both as historical readings. Confirm access before driving out.
