The Great Ice Age Floods: Nature's Power and Beauty in Northwestern Landscapes


Rugged scablands, rippling loess hills, high basalt plateaus, and plunging river canyons make up the Northwest’s dramatic landscapes. Only recently have scientists accepted what was once thought to be an outrageous tale of how they came to be. Follow the path of The Great Ice Age Floods across Washington to Oregon's Columbia Gorge and learn why the National Park Service is establishing a Geological Trail here. Touch the land yourself and step back to wonder at nature’s force.
