About this map

Castaic and its surrounding canyons are captured here during a period of transition as the Ridge Route (US 99) and Ca 126 began to modernize regional travel. The landscape is defined by the sharp contrast between the active agriculture at Wayside Farm No 1 and Wayside Farm No 2 and the steep, undeveloped slopes of the Angeles National Forest and Temascal region. Small family and community nodes like Valverde Lodge, San Martinez, and Liveoak appear along the canyon floors, indicating the early residential footprint of this portion of northern Los Angeles County.

Industrial and transport infrastructure is anchored by the Southern Pacific RR corridor following the Santa Clara River. Notable aviation history is marked by an Airway Beacon near Foothill Sta, while local services are represented by the Castaic Guard Sta and the station at Castaic Sta. The complex drainage system of Hasley Canyon, Charlie Canyon, and San Martinez Chiquito Canyon illustrates the hydraulic geography that shaped road placement and settlement patterns before mid-century expansion.
