Dry Falls
The Dry Falls ( English for dry waterfalls ) are a geological formation in Grant County in the US state of Washington , which was formed by the Missoula floods at the end of the last ice age. The Dry Falls are 5.6 km (3.5 miles) wide and 122 meters (400 feet) high. During the floods, the Dry Falls formed the largest known waterfall in the history of the earth. The estimated discharge was ten times that of all modern rivers worldwide. The large pools at the foot of the falls were eroded by the waves.
The Dry Falls are now part of the Sun Lakes-Dry Falls State Park near Coulee City on Washington State Route 17 and can be reached from Interstate 90 in about an hour's drive.
