Heat Flow Contours of the United States.
Drawing not to scale.
Heat flow contours are patterned in intervals of 20 milliwatts per square meter (mW/m²). Highest temperatures will be associated with areas that have both high heat flow and rock strata with high thermal conductivity.
The area along the San Andreas fault has moderate to high heat flow. In fact, The Geysers geothermal system is associated with the tectonic effects of the San Andreas fault system. The Sierra Nevada Mountains are notable as one of the lowest heat flow and crustal temperature areas on earth.
