Color vertical photo of the Lower Yellowstone Falls, Yellowstone River in Yellowstone National Park, on a sunny mid July day. The narrow rapidly flowing river flows through a stone canyon with evergreen trees almost to the waterline. The river turns into a white water, solid stream dropping 300 foot to the lower canyon, just off the lower edge of the photo. Tiny figures of tourists stand on a small rocky point near the top of the falls. The top of an evergreen tree appears at the bottom of the photo, just below the location of the camera.
