Scene notes:

… in wilderness under clouds where the sun is seen. An exemplar of Altocumulus Castellanus near the center of the frame. Underlit with purple sunlight filtered from smoke, these clouds tower, owing that their names are derived from castle towers. At the end of playback, the sun can be seen brilliantly going down before disappearing into night. An airplane is seen zooming past in the sky, twice, in the upper-left frame. Upper-level Cirrocumulus clouds are gold in their altitude which gives them brilliant direct sunlight to the end.
