Here is a view from Dante’s View in the Black Mountains.
That “white stuff” you see is salt. That part of the valley below is called Bad Water and is the lowest point in the Western Hemisphere. This, of course, is Death Valley.
Bad Water lies 282 feet (86 meters) below sea level and that point lies somewhere amidst those salt flats you see in the middle of the picture. You can get up close to those salt flats and even walk onto them. In the evening, when the sun is low, you can also make for some great photos there.
This overlook at Dante’s View however is quite ways away as you need to go all the way around the mountains to get there. It is a bit of a trip, but as you can see the view is quite spectacular. Be prepared for heavy winds though which is quite common there.
