1898 Map of Mt. Diablo

USGS Topo · Published 1941

About this map

Mt. Diablo and its twin North Peak dominate this landscape, which in the late nineteenth century was a center of industrial activity. To the north, the presence of the Empire R. R. and the Star Mine points to the region's coal mining era, supporting settlements like Nortonville, Somersville, and Stewartville. These mining towns are linked by steep terrain and passes such as Kirker Pass, while the agricultural valleys to the west and south show early development in Clayton, Danville, and San Ramon.
