Dry Falls is a 3.5 mile (5,600 m) long canyon in central Washington, opposite the Upper Grand Coulee from the Columbia River, and at the head of the Lower Grand Coulee. During the last ice age, catastrophic flooding channeled water and glacial ice originating from Western Montana and Idaho at an estimated 65 miles per hour over this 400-foot (120 m) rock face. It is estimated that the falls were five times the width of Niagara Falls with 10x the flow of all the current rivers in the world combined during this time. No water currently flows over the falls but there is standing water in the many pools left when the river dried up. Check out the video below, watch in 1080p or 4k for best results.
