1934 Map of Los Viejos Hills

About this map

The Kettleman Hills rise prominently in this Kings County landscape, characterized by the distinct geological features of Middle Dome and South Dome. Surveyed in the early 1930s, the map reveals a series of Spanish-named landforms and small outposts such as Los Medanos, La Lomica, and La Esquadilla that dot the arid terrain. The topography is defined by a network of seasonal watercourses, including Arroyo del Paso and Arroyo del Conejo, which carve through the ridges and valleys. Infrastructure is centered on the Paso Robles Highway and the Hanford Road, providing critical connections through Pepper Grass Valley. The presence of features like Bullwheel Ridge and Broken Hill points to the area's physical complexity and the early transit routes established across the central valley hills.
