This photo depicts movement of water as it descends in a waterfall from higher to lower elevation. These falls are 40 ft tall and 100 ft wide. In this specific photo, taken in mid-February, much of the water was still frozen, but there was still large amounts of water flowing. These falls were most likely formed as a result of water flowing over different layers of rocks which have different erosion patterns. Over time the earth underneath the water gets steeper and steeper until, eventually, a falling out may occur (which causes the drop). What I find interesting about this photo is this velocity of the water. While it may be difficult to see, the water in this photo is flowing with quite a force and the sound of it was also quite loud. The angle of this photo doesn't depict the "drop" accurately because it was taken at the top of the falls, but the water continues to fall for 40 ft until it reaches the bottom.
