JB,

One of our NE members passed on to me, Craig had beed returning to camp to get more water for the group, who may have run out of water. He had stopped by a tree to rest and sleep and was found there after the search, several days later.

I would guess heat exhaustion, dehydration would have been factors.

When we hunted it was "Winter" and relatively cool and also dry. Now it would be very hot with high humidity. Middays would be like a baking humid oven.
