The San Diego River and the Sweetwater River define the northern and southern bounds of this late-sixties suburban landscape. The valley floor is dominated by the dense street grids of El Cajon, Santee, and La Mesa, while surrounding slopes like Granite Hills and Hidden Mesa show more sparse residential development. In the center of the valley, Gillespie Field and the adjacent Cajon Speedway represent the era's regional infrastructure and recreational hubs.
