Harvey Butchart's Hiking Maps and Notes. This is a link to the archives at Northern Arizona University. Dr. Butchart was the ultimate explorer of the Grand Canyon's backcountry- he discovered and rediscovered numerous rim-to-river routes and made sixty first ascents of Grand Canyon summits. He kept meticulous notes and maps from his 12,000 miles of hiking over his 30-year Grand Canyon hiking career. Warning! These notes are of little use until you have gained some Grand Canyon hiking experience.

It is not enough to understand the natural world. The point is to defend and preserve it. -Edward Abbey
