About this map

Temblor Range peaks dominate this mid-century survey along the high-desert border of San Luis Obispo and Kern counties. This is a landscape of isolated livestock operations and scattered water sources, where remote outposts like Las Yeguas Ranch and Ross Ranch anchor a network of ephemeral streams and canyons. The presence of a dedicated Landing Strip near the ranch indicates the necessity of aerial access in this sparsely populated region during the late 1950s.

The map reveals a high density of named water sources essential for desert survival, including Antelope Spring, Taylor Spring, Bull Spring, and Wygal Spring. These features, along with drainage systems like Carneros Canyon and Cedar Canyon, delineate the difficult terrain. Traces of human activity are minimal beyond the ranching infrastructure, marked by a few Jeep Trails and a lonely Tower standing against the ridges.
