Abstract
Three distinct geothermal regimes are inferred in the vicinity of the city of Clearlake, California. The first is conductive heat flow regime, the second is a fault controlled hot spring flow of "magmatic" fluids, and the third is a resurgent flow of meteoric warm water. The conductive heat flow results in smooth, horizontal isotherms. The hot spring generates a localized spike in the isotherms. The advective disturbance carries heat laterally to a fault line resurgence, lowering the apparent heat flow at the surface.
