March Air Force Base anchors the southwestern corner of this inland California landscape, marking a period of significant military presence and nascent suburban expansion. The settlements of Sunnymead and Moreno are shown during a transitional phase, with residential street grids like Grevillea Avenue and Eucalyptus Ave beginning to fill the valley floor. To the north, the terrain shifts abruptly into the folded ridges of The Badlands and San Timoteo Canyon, where the Southern Pacific railroad follows the natural topography. Local infrastructure is well-defined, from the Perris Valley Storm Drain to educational landmarks such as Alessandro Jr High Sch and Midland Sch. This 1967 survey, with 1980 revisions, captures the area before the intense urbanization of the late 20th century, balancing high-country features like Mt Russell with the industrial utility of a Gravel Pit.
