Publisher's Synopsis
'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.
