1953 Map of Altamont

About this map

Altamont Pass serves as the primary corridor through the hills on this 1953 topographic study, updated in the early 1980s to show the expanding footprint of Livermore. The eastern edge of the Livermore Valley is dominated by the sprawling complex of the Lawrence Radiation Laboratory, a site that defines the region's mid-century shift toward scientific research. The transportation network is highly developed, featuring the parallel routes of the Southern Pacific and Western Pacific railroads alongside Scenic Ave and Tesla Road. Away from the urbanizing valley floor, the landscape rises into the ridges where Patterson Pass and Crane Ridge overlook seasonal waterways like Arroyo Mocho and Arroyo Seco. Local infrastructure is noted by several neighborhood schools, including Summit Sch and Green Sch, along with industrial markers such as the Filtration Plant and Landing Strip near the Patterson Reservoir.
