FSX Scenery--Death Valley Desert Strip. Death Valley Desert Strip (L51) was constructed as a location to test the Aeroworks ARX-6 Reno racer at low altitudes. This place even sports the world's lowest Formula 1 race course! But now that the ARX6 has been released, this facility has been converted to a desert retreat. It's still used occasionally as a test facility for other things and as a filming location. Scenery by Joshua B. Nyhus and Jason L. Terry.
