About this map

The settlement of Midway anchors this 1912 survey, situated at a critical junction of transportation and geography along the Alameda Co San Joaquin Co line. This preliminary edition highlights a landscape in transition, where the intricate topography of the Altamont Pass area meets the valley floor. The map documents the competing infrastructure of the era, showing the parallel routes of the Southern Pacific and the Western Pacific railroads as they navigate the coastal range's eastern slopes.

North of the rail lines, the drainage patterns of Mountainhouse and Patterson Run are meticulously detailed, providing a clear record of the watershed before mid-century agricultural and infrastructure developments. A significant portion of the sheet is noted as a Preliminary Edition Unsurveyed Area, reflecting the ongoing work by the Department of the Interior and the State of California to map this strategic corridor connecting the Central Valley with the coast.
