1937 Map of Violin Canyon

About this map

Cordova Ranch and Daries Ranch anchor the lower drainage of Castaic Creek in this mid-1930s survey of the northern Los Angeles County mountains. The map documents a critical period of infrastructure development within the Angeles National Forest, showing the winding path of Route 99 and the Marple Canyon Highway before modern freeway expansions. An Airway Beacon stands near the center of the sheet, reflecting the era's reliance on visual navigation aids for transcontinental flight paths over the high ridges. The landscape is defined by deep incisions like Violin Canyon and Marple Canyon, where early transmission lines and mountain trails provided the only access through the Temascal region. In the south, the terrain opens into Castaic Valley, illustrating the intersection of rural ranching life and emerging transportation corridors.
