## About High Rock Spring

A warm spring in Lassen County, High Rock sits roughly 26 miles out from Janesville in dry country. The water is tepid, comfortable enough in summer heat and too cool for a winter soak. The USGS keeps a site number for it. Nothing in the record names a land owner, and public access has not been logged. No photo exists.

You park and walk about five hundred feet. That is all the record says about the approach, and it gives no road name. Snowfall is light for the region and annual rain is meagre, so expect dry ground most of the year. The spot sits around four thousand feet, with no land unit listed.

Black Mountain Lookout is the nearest campground on file, nearly nineteen miles off. Winter months score highest on the best-months list. With water this cool, a hot day suits it better than a cold one. Check land status before you go; none is recorded here.
