1955 Map of Mt. Day

USGS Topo · Published 1991

About this map

Mt Day and the surrounding heights of the Diablo Range define this 1955 survey area, straddling the boundary between Alameda and Santa Clara counties. The landscape is dominated by steep ridgelines like Oak Ridge and Poverty Ridge, separated by deep drainage systems such as Arroyo Hondo and Alameda Creek. This map captures a largely undeveloped wilderness prior to the expansion of regional park systems, though the beginnings of public land management are visible at Camp Ohlone Regional Park and Joseph D. Grant County Park.
