Don't forget to drop into Furnace Creek airstrip in Death Valley and take a pic of minus 200ft on your altimeter.......
In fact an overnighter in the Inn at Furnace Creek is a worthwhile experience: the rattlesnake is good (tastes just like chicken
) and the accomodation is superb.
Seriously though: in the little hut at Furnace Creek strip (which is unmanned) is a free telephone: Call the Inn and they'll come and get you.
There is also the Ranch at Furnace Creek but haven't stayed there so can't comment
