Summary

Spectacular floods changed the landscape of Oregon and Washington some 17,000 years ago, when Ice Age glacial dams near Missoula, Montana, broke apart and unleashed an inland sea. The powerful flood--what geologists believe was the greatest moving body of water in the earth's history--tore open the landscape of eastern Washington, merged with the Columbia River and left what is now Portland, Oregon, under 400 feet of water. The floods carried fertile eastern Washington soil 600 miles to Oregon's Willamette Valley, forming the base for the thriving agriculture in the valley today
