Boquillas Canyon, Campanile Boquillas. In January, 1997, I soloed Campanile Boquillas (IV 5.10 A2), which ascends a 500-foot limestone tower on the right (Mexican) bank about one mile into the canyon. The route starts in a chimney on the left edge of the face that faces the river and then wanders up the center of the face to the summit with three points of aid. On the same trip, I soloed the Left Rabbit Ear (5.9) in the Rabbit Ears Spire from the notch.
