Rogers Dry Lake is within the boundaries of Edwards Air Force Base in California, approximately 100 miles northeast of Los Angeles. Rogers Dry Lake is part of the Antelope Valley region of the Mojave Desert and is bounded by the Soledad Mountains, the Sierra Pelona ranges of the San Gabriel Mountains, the Long Buttes, and the Tehachapi Mountains. The lake forms the lowpoint of the Antelope Valley which ranges in altitude from 2,300 to 3,000 feet above sea level.
Rogers Dry Lake is sixty-five miles square and shaped roughly like a lopsided figure-8, 12 1/2 miles long and 5 miles wide. It is a pluvial lake that was formed during the late Pleistocene Era about 2.5-million years ago. The lake is naturally flat and its surface is unusually hard and can support up to 250 pounds per square inch of pressure enabling even the heaviest aircraft to land and take off from the lake bed. The lake is dry for most of the year except for brief occasions when rainfall fills the lake bottom to a depth of a few inches.
Rogers Dry Lake has 60 miles of marked and maintained runways which are 300 feet wide. Its broad expanse of hardened clay surface forms the largest natural landing field in the world.
