Nevada range in the great basin and the mojave desert, it comprises much of
Death Valley National Park. It runs north-south between the amargosa range to the east and the panamint range to the west; the sylvania range and the owlshed mountains form its northern and southern bounaries respectively.
Landsat 7 imagery of Death Valley. Green indicates vegetation, which increases with altitude. The varying shades of brown, beige, and rust indicate bare ground; the different colors result from varying mineral compositions in the rocks and dirt. Although they may appear to be pools of water, the bright blue-green patches in the scene are actually salt pans that hold only a little moisture.-wikipedia
