I spent an off-day wandering Death Valley. Pics are from all over, from the Mesquite Dunes at Stovepipe Wells, to Badwater, to Ubehebe Crater. The last of these is the only place I did any significant hiking (it was about 105 by late afternoon.
The view above the craters is worth the climb, no matter how hot it is, but the trail is mostly loose cinders, so it's quite a slog.
The burros and little tiny mule are from the ghost town of Ballarat in neighboring Panamint Valley.
Edit: I ate some salt from an untrampled part of Badwater Basin. It tasted like salt. According to what I read about the deposition process, it probably was mostly sodium chloride based on where I sampled it. Also, I saw a mangy kit fox near Grapevine Canyon.
