About this map

Glendora, San Dimas, and La Verne anchor the southern base of the San Gabriel Mountains in this 2015 study. The landscape is defined by the transition from dense suburban residential grids to the steep, canyon-riven slopes of the Angeles National Forest. Significant water management infrastructure is visible throughout the area, including the large San Gabriel Reservoir and Morris Reservoir to the northwest, alongside smaller catchments like Big Dalton Reservoir and San Dimas Reservoir.

The map details the intricate drainage network flowing from the peaks, such as Little Dalton Wash and San Dimas Wash, which cross through the developed valley. Geologic and local history are reflected in the naming of numerous canyons and flats, from Graveyard Canyon and Minero Canyon to Hoot Owl Flats. The southern portion of the sheet reveals the established street layouts of the San Gabriel Valley, including a segment of the historic Route 66.
