1953 Map of Clayton

About this map

The dramatic rise of Mount Diablo dominates this mid-century survey, showcasing the sharp contrast between the expanding suburbs of Concord and the protected wilderness of Mount Diablo State Park. In the valleys below the peaks, the residential footprint of Clayton and Cowell is clearly delineated, showing the early stages of post-war development encroaching on the region's agricultural and industrial roots. Notable landmarks include the sprawling Concord Naval Weapons Station to the north and the historic Nortonville (Site) on the eastern slopes, a reminder of the area's coal mining heritage.
