In a moonlit night of Canadian Rocky Mountains stars trails above Takakkaw Falls in the World Heritage area of Yoho National Park, British Columbia. The falls is 384 meters from the top to the base. Note the colorful arc of moonbow near the falls base. Moonbow is a rainbow produced by the moonlight rather than the sunlight. It is relatively faint, due to the less amount of light from the Moon. See this view in a time-lapse video.
