I wonder if park service is going to take more precautions from people dying for the heat. I know they can on do so much but what are people thinking trying to hike in summer heat. I know from military time you do not fool around in the desert. N Africa is hot and Libya was no exception even being prepared you are in danger. the was a book about deaths in DV and they stated more people have died in DV from the 30' to present than the old days. be safe SVJ Greenwater site
