that's just tragic.

the problem is the overwhelming HEAT and the lack of shade. There are no trees. there is no place to escape the sun.

I was caught once in similar conditions. I have PLENTY of liquids and Gatorade. it almost didn't matter. It is possible for the body's defense mechanisms to be overwhelmed by heat loads ... you get faint, thinking gets muddy, and its a downward spiral. Fortunately, I got my truck un-stuck and got the heck out of the desert. NEVER AGAIN!!
