Hearing the faint strains of the shaman’s voice chanting, Sam followed the sound to the edge of the cliff. The song came from somewhere below. Sam spent some time looking around, until he finally found what resembled a path downward. He had to scramble in a couple of places, but he made his way to a narrow level area and followed it along the edge of the sandstone bluff. Turning the corner of an outcrop, he came suddenly upon a structure more elaborate than those he had seen in the opposite wall of the canyon. Building after ruined building was crammed into the gash in the cliff. In one place a tower reached up almost four stories, molding itself to the curving overhang of the cleft. Hard-packed earthen surfaces with square holes in their centers marked kivas. Sam skirted the exposed circular wall of one in order to follow the chanting.
