1981 Map of Lancaster

About this map

The high desert landscape of Antelope Valley transitions from the sprawling residential growth of Lancaster and Palmdale to the massive infrastructure of the Edwards Air Force Base flight test center. This 1981 survey documents the path of the California Aqueduct as it skirts the northern edge of the Portal Ridge, fundamentally altering the water distribution for this arid region. The geography is defined by the San Andreas Rift Zone, a visible tectonic scar running through the Sierra Pelona and Angeles National Forest. To the west, the Golden State Freeway provides a primary artery through the mountains, passing near the Fort Tejon State Hist Park and the rugged peaks of the Los Padres National Forest. The map also captures specialized land uses, from the Antelope Valley California Poppy State Reserve to the Sespe Condor Sanctuary, highlighting the region's diverse environmental conservation efforts amidst mid-century expansion.
