2021 Map of Altamont
USGS Topo · Published 2021About this map
Altamont Pass serves as a critical geographic gateway where the coastal mountains meet the San Joaquin Valley. This 2021 survey illustrates the complex modern infrastructure of eastern Alameda County, featuring the winding South Bay Aqueduct and the primary transit corridor through the hills. While the expansion of Livermore is evident in the residential developments near Trevarno, the landscape quickly transitions into the open cattle country and wind-swept ridges of the Diablo Range.
