Mount Boardman is located in the Diablo Range in California. The summit is near a point where Santa Clara, Alameda, Stanislaus, and San Joaquin counties meet. It was named for W. F. Boardman, the Alameda County surveyor between 1865 and 1869. There is a higher peak to the north which is unofficially called Boardman North and has an elevation of 3629 ft. This north peak, unnamed on topographic maps, is located on the Alameda – San Joaquin county line, and is the highest point in San Joaquin County. Some snow falls on both peaks during the winter.
