As we scrambled the scree slope to the mesa top, a lovely thing. The limb of an ancient juniper, vibrating in the cliff-edge wind, had worn a deep groove in the sandstone it leaned on, and had rubbed itself down to bare wood.
The fit was perfect even to the wood grain. A protruding knot on the limb had made a perfectly matching, knot-shaped hollow in the stone.
I was reminded of a word from…is it San Felipe Pueblo? Suyu: the sound of the wind as it hits the edge of the mesa.
