在冰河世纪世界上最大的瀑布，但是随着时间的流逝，环境的破坏，目前只留存干涸的身影.
Approximately 12，000 years ago， over 3，000 square miles of water from Lake Missoula covered Northwestern Montana and was held back by an enormous ice dam， over 2，000 feet tall. As the glacier melted， the lake rose until the pressure burst open the ice dam. This resulted in a flood beyond all proportions that swept through the Idaho Panhandle， Spokane River Valley， across Eastern Washington to the Vantage area， and parts of Northern Oregon， covering the region in 400 feet of water.
