The Emerald Mile

Best book I've read in a long time. At first it just seems like it's about some dudes trying to break a speed record for running a river, but it turns out to be a history of the Colorado River, the Grand Canyon, the Glen Canyon dam, conservation ... and then the adventure aspect of running the Colorado in flood stage. Impressively well-researched and very well-written. Any of my peeps that are into the outdoors or history – read this.
