1953 Map of Altamont

About this map

Altamont Pass serves as the focal point for this landscape, where the Southern Pacific and Western Pacific railroads converge to navigate the steep grade out of the Livermore Valley. The 1953 topography is overlaid with significant late-1970s updates, particularly visible in the expansion of Livermore and the massive footprint of the Lawrence Radiation Laboratory. This juxtaposition reveals the rapid transition of the area from a rural ranching and rail corridor into a hub of scientific research and suburban growth.
