1967 Map of Lake Mathews

About this map

Lake Mathews dominates the northern landscape, its waters held by the Mathews Dam and a system of dikes that transformed this portion of the El Sobrante De San Jacinto land grant. This area serves as a critical infrastructure node, where the Colorado River Aqueduct terminates and the Atchison Topeka and Santa Fe railroad runs along the Temescal Wash. Evidence of early California history is anchored at the Site of the First House in Riverside County near Arcilla, alongside an Indian Pictographs Historical Marker. The terrain rises from the industrial floor of the valley, marked by a Gravel Pit and Quarry, toward the high peaks of Arlington Mtn and Estelle Mtn. To the southwest, the Cleveland Natl Forest provides a backdrop for the resort area at Glen Ivy Hot Springs.
