I've never been to the Grand Canyon, but it's safe to say that in the lexicon of American canyons, this place is firmly in second place. The narrow openings and walls of this canyon offer startling depths. Very startling. As somebody who is terrified of heights, this place did freak me out a bit. But looking back on it from the safe confines of flat land, I realize it's one of the most amazing things I've seen.
