1981 Map of Lancaster

About this map

Antelope Valley stretches across the center of this 1981 survey, serving as a vast transition between the high desert and the steep ridges of the Tehachapi Mountains and Sierra Pelona. The San Andreas Rift Zone is a dominant geological feature, slicing through the landscape and influencing the location of settlements like Lake Hughes and Elizabeth Lake. Transport and energy infrastructure are prominent, with the California Aqueduct winding along the valley floor and major routes like the Golden State Freeway and Antelope Valley Freeway funneling traffic through the passes. To the east, the sprawling footprint of Edwards Air Force Base and Air Force Plant 42 highlights the region's importance to the aerospace industry. Mining history is preserved in the Bissell Hills area with the Golden Queen Mine, while natural conservation is represented by the Sespe Condor Sanctuary and Antelope Valley California Poppy State Reserve.
