"He ate his lunch at noon in an outcropping of lava rock with a view across the floodplain to the north and to the west. There were ancient pictographs among the rocks, engravings of animals and moons and men and lost hieroglyphics whose meaning no mean would ever know. The rocks were warm in the sun and he sat sheltered from the wind and watched the silent empty land. Nothing moved."
