Surviving Grand Canyon Gary Barnes

'Surviving Grand Canyon: It's All About Water' is Part 1 of 5 in the series based on 'A Walk in the Deep Big Empty: The Science for Surviving Grand Canyon.' The book contains some detailed 'Science' ranging from human physiology to geology to human psychology. It is meant only for those with a curious mind and a willingness to put in the hard work necessary to master some difficult concepts. It you hated math and science in high school, this book is not meant for you. If you are up to the challenge, consider this book your guide to the both the entry-level hiking trails as well as the more difficult primitive trails in Grand Canyon. Mastery of dehydration, hyperthermia, and hyponatremia and the other topics will get you into and out of the Grand Canyon via your own two feet and not hauled out via a body bag.

Survival topics discussed all revolve around the importance of Water: (1) Dehydration, (2) Hyperthermia, (3) Hyponatremia, (4) Voluntary Dehydration, (5) Water Discipline and Water Rationing, (6) Should you Drink Urine? (7) Getting Water-and-Salt Calibrated, (8) What the Desert 'Experts' recommend, (9) Water Quality and Sources at Grand Canyon, (10) Breccia pipes and Radioactivity, (11) To Drink or Not, (12) Canyon geology and finding water (13) Seeps, Puddles, and Potholes, (14) How to treat water to make it safe, (15) Flash floods, (16) Trapped in a Waterfall, (17) Water Management and Planning your Hike. Successful and tragic 'thirsty hiker' scenarios are analyzed for what went right-and what went wrong.
