The red sandstone rested nowhere near a hillside or rocks of the same material. Sam picked it up and looked it over.
The surface had a petroglyph of the humped back flute player, Kokopelli, in black and not the usual dark red pigment. Sam slipped it in his pack.

He stepped out onto his front porch to listen. An unfamiliar blackness overcame him.
Once conscious, Sam found himself pressed into the stone and the flute player dancing around a fire.
