1958 Map of Ritter Ridge

USGS Topo · Published 1975

About this map

The high desert landscape of Sierra Pelona and the Anaverde Valley is defined by the critical infrastructure and mining activity of the mid-20th century. The California Aqueduct snakes across the northern slopes of Ritter Ridge, utilizing specialized engineering features like the Ritter Siphon and Leona Siphon to move water through the arid terrain. While the emerging city of Palmdale occupies the eastern edge near Lake Palmdale, the surrounding canyons remain a network of family-named settlements and industrial sites. In the southern reaches, several historical mining operations are clearly marked, including the Puritan Mine, Red Rover Mine, and Governor Mine. These sites, along with isolated outposts like Messer Ranch and City Ranch, provide a detailed record of land use and resource extraction in Los Angeles County before the full weight of modern suburban expansion reached this portion of the Antelope Valley.
