Scene notes:

As the point-of-view pans to the right over melting ice on a foreground rock, the fog, just beyond the close tree line below, begins to inundate. Sunbeams are observed during moments of time when the fog’s upper visible limit is the same altitude as the trees. On a grassy slope that comprises the middle ground, the fog eventually becomes an obscuring factor in the sunset light.
