Snow Mountain is a mountain in Northern California in the Snow Mountain Wilderness of Mendocino National Forest. The highest point on the mountain, known as Snow Mountain East, is the highest point in both Colusa and Lake counties. Snow Mountain West, a subsidiary peak also near the county line, is 0.58 miles (0.93 km) to the southwest at an elevation of 7,043 feet (2,147 m).
On clear days, the peak should be seen from Mount Diablo, and from several peaks, including Mount Saint Helena and Mount Konocti, in the Mayacamas Mountains. The peaks are visible from Arbuckle on Interstate 5 in California's Central Valley. The summits and nearby high mountains get snowfall in winter. The mountain's winter snowpack can last until June.
