About this map

The Diablo Range terrain of the Alameda and Santa Clara county line is defined by the steep watersheds of Arroyo Honda and Isabel Creek. This 1955 survey, updated with 1971 aerial data, captures the remote character of Camp Ohlone Regional Park and the high points of Mt Day and Black Mtn. The landscape is a network of ridges and flats, featuring Poverty Ridge and the broad Cañada de Pala.
