Scene notes:

Towering Congestus Clouds, benefiting slightly from orographic lift, float from the peaks of the southern Sierra Nevada range. As tall as the mountains they seem to stand on, they transform as they grow and lose energy away from the peaks, evaporating. On these snowy mountains, their shadows travel. Under the blue sky, which is four-fifths of the frame, high Cirrus clouds move the opposing direction.
