Scene notes:

The snow-covered rim of both the north and southern rim of Grand Canyon is highlighted under moving lower, fluffy clouds. Clouds from outside the frame cast their dark shadows on the cliffs and rim as they pass swiftly in the winter wind, their transformations almost muted playsinline compared to the clouds of summer. The lower temperatures are responsible for the relatively sluggish air currents around and in the clouds themselves.
