Scene notes:

Altocumulus mackerel undulating, casting. An extremely large ‘arete’ shape on the mountain across the valley, massive and snow covered, formed from glaciers on both sides creating an axe-shaped ridge. Like the scales on a Mackerel, the mid-level clouds cast shadows on the vista of mountains beyond, wooded with evergreens and snow, as the town of Banff sits below-right. Time-lapse length (at 30 fps): 5 seconds and 25 frames.
