Non-fiction book review: Grand Canyon: A River at Risk

Fantastic!  The photography is wonderful, and the backstory to the history of the Colorado river is engaging.  Most of all, this is the story of how our fresh water supplies are in jeapordy-- and without that, we've got a whole lot of nothing.  This is a fascinating read for anyone who is worried about our planet, and a must-read for anyone who isn't. This book is a companion to the Imax film of the same name.
