About this map

Estrella River winds through a landscape of deep canyons and scattered agricultural settlements in this late 1940s survey. The area’s rural character is defined by a series of prominent drainages, including Hog Canyon, Keyes Canyon, and Freeman Canyon, which cut through the terrain toward the river valley. Evidence of mid-century infrastructure and local aviation is present at the Paso Robles-San Luis Obispo County Airport and a small Airstrip near Hillman Ranch.

Educational life in this part of San Luis Obispo County centered on several small rural schoolhouses, such as Pleasant Valley Sch, Phillips Sch, and Union Sch. The small settlement of Whitley Gardens sits at a crossroads near the river, while the proximity of numerous Windmill sites across the ranchlands highlights the importance of groundwater for the region's ranching economy. A small Cem near the river provides a point of interest for genealogists tracing early residents of the Estrella area.
