Zoo wall from the bottom of the canyon. Climbers can be seen on the left portion of the photo and below an overhang on the top middle of the photo. If you don't want to hike around to the left and up some switchbacks, you can always climb up the 4th class gully in the right 1/4 of the photo to get to the 5th class routes above. It's not that easy with a full load of gear. March 19, 2004.
