About this map

The Montezuma Hills rise above the complex delta where the Sacramento River and San Joaquin River converge. This map documents a landscape defined by industrial development and the intricate waterways of the Sacramento Valley, showing the urban expansion of Pittsburg and Antioch along the southern banks. The northern portion remains characterized by wind-swept hills and isolated settlements like Collinsville and Montezuma, where the Collinsville Cem provides a point of interest for genealogists.

Water management and maritime commerce are evident through features like the Sacramento River Deep Water Ship Channel and the Mokelumne Aqueduct. These engineering works slice through the low-lying islands, including Winter Island and Browns Island, illustrating how the delta's natural hydrology has been modified to support the region's growth. In the southeast, the residential and commercial areas of Oakley and Bridgehead mark the edge of the contemporary suburban landscape.
