Yes, that is something I usually try and do. Modern commo technology can come in pretty handy.
The Superstitions are a rough bit of terrain. You get hurt in some of those places, you might as well be on the surface of the moon. Hardly a year goes by when they don't find someone dead in the Arizona outback. The climate in Arizona can be rough.
One interesting story I know of of people underestimating the Arizona climate was from the 1940's involving some German soldiers.
The USA was shipping a lot of it's captured German soldiers to Arizona. Some Weremacht lieutenant at an Arizona POW camp about 40 miles SW of where the lost hiker story took place got hold of a map that showed the Gila River not far away, and the map showed the Gila ('Heela') River going all of the way to Mexico.
So, in a story reminiscent of a WWII Hollywood escape movie, they hoarded supplies and made an inflatable boat out of raincoats.
When they were ready, they escape from the camp and they get to the Gila River and it's dry as a bone. It really only has any water in it in that area during the rare flood. So they figured that they would just walk to where the water started, and then raft on down to Mexico and freedom..
Well, they found these guys a few days later on death's doorstep, desperately in need of a drink of water while on the Gila 'River'..
