If You Make a Mistake, You Die.

Currently 3 men from Salt Lake City are missing in the Superstition Mountains east of Phoenix.  They went to this Wilderness Area to find the Lost Dutchman Goldmine, an enduring legend that has claimed at least 40 - 50 lives.

Fools gold, fools to the end.
They ventured into this environment with no resources...no water, no knowledge of the desert, no imagination.  
Water is available throughout the Superstitions.  Springs are numerous and you can spot them from the light green shrubs and trees that surround them.  Some say they can smell it.  If the men die of thirst with the lights of Phoenix glowing on the horizon, I'm sure there is an old expression that applies to their foolishness.
I've hiked every trail in the Superstitions, often when temps are 110+, and a good part of the fun is the implicit challenge that, if you make a mistake, you die.
That was for fun, the challenge.
If you die for a vaporous legend of gold, shame.  Unfortunately, the men are past reproduction age and their genes have likely been passed along.
Much of my caution in the desert comes from the realization that thirst is maybe one of the worst ways to die.
I should go there soon, for the nostalgia, the thrill, for the knowledge that it's a risk activity. . . to get my soul back.
