Mount Saint Helena

Mount Saint Helena (Wappo: Kanamota, "Human Mountain") is a peak in the Mayacamas Mountains with flanks in Napa, Sonoma, and Lake counties of California. It is one of the few mountains in the San Francisco Bay Area to receive any snowfall during the winter.

The mountain has five peaks, arranged in a rough "M" shape. Its highest point, North Peak, is in Sonoma County. The second-tallest, immediately east of the main summit, is the highest point in Napa County.
