Right in Janesville, or as close as makes no difference, a thermal point logged as Springs sits a few dozen feet off a road. Warm water, the sort you could stand in without flinching. The record gives no landowner and no word on public access, which for a spot inside a town is worth taking seriously. The USGS assigned it a site number and left it at that.

Location

Roadside, and the road goes unnamed on file. Lassen County on the record. Elevation around 4,500 feet and winters with about two and a half feet of snow. Precipitation is moderate. There is no land designation or land unit on file to go with the missing owner.

Cold months rank highest. Because the spring is in or beside town and ownership is unrecorded, assume someone owns it and ask first. No fee, no camping, no chemistry listed. The warm reading comes from the USGS listing and has no sample date attached. There is no photograph to tell you what you are looking for.

Terrain

Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Springs.

Heat Below
114 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 66% 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.
