Scene notes:

After blue hour, mid-level clouds, patchy and fleeting, move in steadily in the moonlight, shadows dimly moving on rock faces near the bottom-right of the frame at points. Mt Whitney (center) and neighbors are silhouetted in the night, with nearer mountains that are shorter but much closer on the left and right flanks.
Time-lapse length (30 fps):
20 seconds and one frame.
