75 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 10% 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.
