The rising Full Moon of January 6, 2023 over the Badlands of Horseshoe Canyon, near Drumheller, Alberta. Here the Moon is set a dark blue crepuscular ray (or more correctly, anti-crepuscular ray) converging on the point directly opposite the Sun. The ray was a shadow cast by clouds in the west, which parted enough for a few moments for the setting Sun to light the foreground, making for a colourful contrast between ground and sky.
