Hot Springs, carrying Menlo Baths as a second name, lies in Modoc County off Surprise Valley Road, close to thirty miles from Alturas. It comes out hotter than anyone would sit in undiluted. That second name suggests people bathed here at some point, though nothing describes a pool or any facility, and no owner is named.

Location

From Surprise Valley Road it is roughly a thousand feet on foot. Elevation is around four and a half thousand feet in high, dry country. Winter snow is moderate. Whose land this is does not appear in the record, and neither does a land unit, so you are on your own for figuring out what ground you are standing on.

Patterson Guard Station is listed for camping, about seven miles away. The three winter months top the best-months data. Hot enough to scald if you get in without testing, so test before you touch. Public access is unrecorded, so treat it as unverified until you have seen the place or asked locally.

Heat Below
126 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 76% 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.
