Cow Mountain is a ridge in the Mayacamas Mountains in Lake County, California, and Mendocino County, California. It is home to two large recreation areas. One is closed to off-road vehicles and the other is not. Erosion from the mountain, caused in part by human land use, contributes sediment and nutrients to Clear Lake.
