“ The sun rose over the city just as we reached the narrowest part of the gut, Grim leading, and its first rays showed that we were using the bed of a watercourse for a road. Exactly in front of us, glimpsed through a twelve-foot gap between cliffs six hundred feet high, was a sight worth going twice that distance, running twice that risk, to see—a rose-red temple front, carved out of the solid valley wall and glistening in the opalescent hues of the morning. “
