1921 Map of Piru

About this map

The Santa Clara River valley anchors this 1921 publication, where the Southern Pacific railroad connects established citrus and agricultural communities during the early 20th century. Settlement is concentrated along the river corridor and the parallel rail line, serving as the economic lifeline for towns like Fillmore and Piru. The map captures the distinct irrigation and land division patterns of the era, notably in Bardsdale and around Moorpark in the Little Simi Valley. To the north, the terrain transitions into the steep elevations of the Santa Barbara National Forest, where features like Oat Mtn and Hopper Mtn loom over the drainage of Little Sespe Creek. To the south, the landscape is defined by the Oak Ridge and Las Posas Hills, highlighting the natural barriers that funneled early transportation and ranching into specific valleys and canyons.
