Flash flood watch for Mojave Desert (more monsoonal rain today) is a double edged sword, IMHO. On the one hand, a flash flood could wash away any evidence that may be out there but not located. On the other hand, a flash flood could also uncover evidence that hadn't been found. Hope it's the latter, if the flash flooding hits the Kelbaker area.
