1907 Map of Tesla

About this map

Tesla and Carnegie serve as the industrial heart of this landscape, situated along a corridor where the Western Pacific railroad follows the winding path of Corral Hollow. This era in the eastern Diablo Range shows a region defined by extraction and early manufacturing, evidenced by the Pottery settlement and a Gravel Pit further east. The transition from the flat agricultural lands of the Livermore Valley and San Joaquin Valley into the steep ridges of Crane Ridge and Cedar Mountain Ridge is marked by vital water sources like Mendenhall Springs and Mud Springs. This 1905 survey also documents the presence of the Southern Pacific railroad skirting the northern hills through Altamont and Midway, illustrating how the topography dictated the vital transit routes connecting the coastal valleys to the interior.
