The water falls 60 feet, causing a mist to rise. This mist also causes a moon bow visible on clear nights under the full moon (not found anywhere else in the Western Hemisphere). This Falls is known as the "Niagara of the South". The 125 foot wide falls is beautiful during the day or at night. Must go see!

Yellowstone National Park, Teton County, Wyoming || Artists Falls in Yellowstone NP. At a certain time in the morning, the sun's rays hit the mist of the falls and create a rainbow. I highly suggest asking a park ranger or guide what time this occurs (it's been a while since I visited, I think around 8-9am) so you can get similar shots.
