Blue hour twilight with a waxing crescent Moon, over the Bow Valley, Banff, Alberta, Canada. The air was filled with smoke from British Columbia forest fires to the west, muting the colours and clarity. This is from the Hoodoos Viewpoint trail on Tunnel Mountain Drive, looking back toward Banff. The lights of the Banff Springs Hotel are in the distance at left. The Bow River winds below. Tunnel Mountain is at centre with Sulphur Mountain to the left and at far left a portion of Mt. Rundle. Cascade Mountain is at far right.
