Total Height: 1291 feet 393 meters, tallest Single Drop: 517 feet 158 meters This one of the tallest waterfall in Montana’s Glacier National Park, Lake Ellen Wilson, USA. The falls are also known as Diamond Falls because as the water falls, it splits into two channels, then converges before it reaches the floor of the valley, forming a jagged diamond shape in the cliff. Prior to 1939, the NPS referred to the falls as Lincoln Falls.
