The drainless salt flat Rogers Dry Lake (also Rogers Lake , Muroc Dry Lake ) is located in the Mojave Desert in Kern County , California , around 160 kilometers northeast of Los Angeles . The name is derived from a translation of the Spanish "Rodriguez" into English .
The lake formed in the Pleistocene is one of the lowest places in the remote Antelope Valley and has a flat surface that has been polished smooth by weather influences. That's why US government agencies use it as a test site for the aerospace industry. The lake owes its classification as a National Historic Landmark to this use .
geology
The lake was formed in the Pleistocene and, with today's Rosamond Lake and Buckhorn Dry Lake, formed a unit that was constantly filled with water and dried out in the Holocene .
At only around 694 meters above sea level, the approximately 114 square kilometer, extremely flat area is one of the lowest places in the Antelope Valley. The dried-out surface is polished again and again when the winds brush the water from winter rains over the clay and silt , so that it appears as smooth as glass. From the surrounding hills as well as the San Gabriel Mountains in the south and Tehachapi Mountains in the west, snow or water occasionally collects in the bare salt flat.
use
The mostly dried up salt lake was first used by the US military as a test site in 1933 , at that time for bomb tests. Today, maintains Edwards Air Force Base , an air base of the United States Air Force , which the NASA Research Center Dryden is affiliated, in Rogers Dry Lake several unpaved runways , one of which (number 17/35) measures over 12 kilometers, thus considered the longest in the world. Because of its remote location and because the hard, absolutely flat surface of the salt flats is a natural extension of the runways, the area is an ideal test site for aerospace. For example, in 1977 the first attempts to land the space shuttle, which is still in development, were made there and in 1984 a crash test was carried out with a Boeing 720 . The site also served as an alternate airport for space shuttle landings. To make orientation easier for pilots, a compass rose of enormous dimensions was drawn on the ground , with a diameter of 1.22 kilometers it is the largest of all.
Because of its importance to the developments in the aerospace industry, Rogers Dry Lake was classified as a National Historic Landmark in 1985.
