When East-coasters think about hiking in the west, it's often altitude which comes to mind. While it's not much of a factor in places like the Northern Cacades, the effects of low humidy in the Southwest and Sierra Nevada, particularly on multi-day hikes, can take its toll.
The first time that I can remember suffering from dehydration (leg cramps) in a really long time was on a very hot and humid day about this time last year on an Isolation loop via the southern end of the Rocky Branch Trail and Davis Path. I guess that I have been more careful out West, as never had problems there other than altitude headaches, although those are also probably in part due to deydration. If only I were a bigger fan of canned anchovies as one hiking friend always carries for lunch.
Thanks for sharing, AlGonquin Bob, and enjoyed reading your survival story.
