Raging Ice Age floodwaters carved spectacular features throughout eastern Washington, creating unique landscapes. Follow the path of the floods and discover more about this amazing story.

Path of Least Resistance
As floodwaters rushed across eastern Washington, they followed existing rivers and streams until they overwhelmed them They then found their own way toward the ocean, going over or around large obstacles and carving new routes wherever they could.

These streamlined hills were sculpted by Ice Age floods. Although not obvious at ground level, their tear-drop shape point in the direction of the floodwaters.
