“Troy’s knowledge added greatly to my Colorado river trip experience. I learned so much more about the history, geology & formation of the Canyon than I ever expected. This, in addition to simply enjoying the awe inspiring scenery is truly the way to expose people to the grandeur of the Canyon and the need to protect it. Your recommendation of Belknap’s Grand Canyon River Guide should be required reading.”
