Those "black" areas in the mojave, are most likely, (lava flows). There are some pretty expansive ones, between Barstow and Ludlow along I-40. That black streak in the "cut", was something you weren't supposed to see. There will be a couple of "government guys" along shortly, to "help" Yaccraps, forget that he saw it. How does an experienced hiker, NOT take enough water, when he goes hiking in the desert? Did you wind up drinking your own urine?
