On only two occasions have I thought I might die: The gravest occasion involved severe dehydration in the California desert, the other occasion involved a stuck gas pedal, a Plymouth and a twisty Wasatch road, but that doesn't concern us.
My brother and I had decided to celebrate my first vacation from that urban blight known as New York by spending a few days in Joshua Tree. I was ecstatic to be back among Western vistas, searing heat and absolute quiet—all of which contributed to an impromptu decision to extend a six-mile, out-and-back hike into a 17-mile loop. It was early still and we felt strong. Our decision was supported by a hiker we met who assured us there was a water faucet at a campground along the loop.
Needless to say, there was no water at that campground. By the last three or four miles, I was suffering the beginning stages of heat exhaustion—nauseated, demoralized and cramping. And scared.
Heat exhaustion and stroke are not conditions to dismiss lightly. In the American wilderness, foreign wilderness, or even a tropical capital city, you need to be aware of heat-related dangers.
Mistakes to Avoid
We were extremely, extremely, fortunate we didn't make an error finding our way back to camp. We had definitely used up our margin for error and made nearly all the mistakes we could have.
We pushed ourselves while still acclimating. I had flown from cool New York to the searing California desert in late spring, allowing my body no time to adjust to the severe heat. Among other things, your body over the first few weeks in a hot climate transfers fat away from the skin and toward internal organs. It also becomes more efficient with water use.
We didn't have enough water. In the hottest of hot conditions, you need to drink what seems like a ludicrous amount of water. A liter every couple of hours is not unreasonable if you are working hard. Take an extra bottle and make certain you know where the next water is.
