There is now this five-minute stoppage in the conversation, and in the hike, and possibly in some of Randy’s neurological processes. The color map of his vision goes out of whack: everything’s in extremely washed-out shades of yellow and purple. Like someone’s clammy fingers are around his neck, modulating the flow in his carotids to the bare minimum needed to sustain life. When Randy finally returns to full consciousness, the first thing he does is to look down at his shoes, because he is convinced for some reason that he has sunk into the wet sand to his knees. But his shoes are barely making an impression on the firmly packed sand.
