Back in July 2009. I joined about a dozen fellas for a weekend photographing at Toroweap Pt Grand Canyon bcause there are usually thunderstorms then so we thought we might catch a nice cloudy sky, rather than an empty blue one.
Since most of the group were over 50-60 years of age, I reviewed the treatment for heat stroke to be certain that I would recognize it - I arrived in St George Utah a couple days early to acclimate to the heat, and the ambient temps in the afternoon were about 114 degrees - even at 10 pm, well after sundown it was over 100 degrees. The road crews were pouring asphalt in the afternon heat - Very humbling, I dont know how they managed to do that without having sick employees.
The first step in treatment of heat stroke is to place the individual in a cool dry air conditioned room and administer IV fluids and cool water to the skin. Since Toroweap is about 100 miles of unpaved road to the nearest asphalt and there was no electricity at the campsites I was a bit concerned about being able to treat heat stroke, and the age of the group suggested there might be some risk.
I had some concerns, but no one had any difficulty with the heat - we got up before sunrise, shot sunrise, and then sat in a portable gazebo we put up for shade, and just drank cold water all day long trying to keep cool. We told lots of stories. Once sunset approached we finally got mobile again and went out and captured sunset. We all had a great time, but I was glad that no one tried to over do it.
