Jackson Valley Mud Springs
Jackson Valley Mud Springs produces 80-degree water from the Mendocino County coast range near Laytonville. The spring's muddy character and 25-degree temperature differential mark this as a geothermally marginal feature with distinctive chemical properties.
The spring sits in mixed evergreen forest and chaparral typical of the North Coast Ranges, where complex geology creates varied terrain. Located just 173 feet from the road, the setting offers the accessibility of a roadside feature combined with forest surroundings that provide some sense of remoteness.
The spring lies in the geologically complex coast range where fault systems drive localized geothermal activity. The muddy character reflects mineral-rich circulation through marine sedimentary and metamorphic rocks common to this region.
Road access places this spring minutes from the highway, making it an easy stop. The area receives 47 inches of annual precipitation concentrated in winter months. Spring and early summer offer the best visiting conditions with stable road access.
