Dry Falls are a product of the Missoula floods of the Ice Ages. The cliffs stand about 350 feet (115m) above the basin floor, and with all their lobes extend about 3.5 miles (5.5km). Glacial Lake Missoula, dammed by ice in what is now Montana, formed and collapsed several times during the Ice Ages. It was about 1/2 mile (800m) deep at it's peak, and even here, about 250 miles (400km) away, it flowed as much as 300 feet deep as it thundered over these cliffs. 10,000 years later, the scarring is visible all over central Washington State, especially with the availability of satellite photos.
