"Cold air rises from the ground as the sun goes down.  The eye-burning clarity of the light intensifies. The southern rim of the sky glows to a deeper blue, to pale violet, to purple, then thins to grey.  Slowly the wind falls, and the still air begins to freeze.  The solid eastern ridge is black; it has a bloom on it like the dust on the skin of a grape.  The west flares briefly.  The long, cold amber of the afterglow casts clear black lunar shadows.  There is an animal mystery in the light that sets upon the fields like a frozen muscle that will flex and wake at sunrise."
