Crabtree Hot Springs, Mendocino National Forest

Crabtree Hot Springs is a geological phenomenon in Lake County, California about 25 miles north of Upper Lake. It is located on private property and closed to the public. It lies at an elevation of 2,257 feet. There is a cluster of four natural hot springs at this location, in an isolated narrow winding steep walled canyon on the north bank of the Rice Fork of the Eel River, about one fourth mile downriver from its junction with Salt Creek. Three of the hot springs are aligned in one area at a large swimming hole, while the fourth hot spring is about 60 feet back upriver. The temperature of the hottest spring is 106 °F, with a flow rate of about 10 US gallons per minute. ()
