Featured Park: Ice Age Floods National Geologic Trail
Ice Age FloodsThousands of years ago enormous Ice Age floods carved a broad swath across a four-state region in the Pacific Northwest. The story of these cataclysmic floods may soon be told through a National Geologic Trail.

Glacial meltwater flowed into ice-dammed lakes. The largest one--Glacial Lake Missoula--covered an area twice the size of Rhode Island. Water and ice from Lake Missoula, which would have filled half of Lake Michigan, swept forth across the land as glacial dams repeatedly broke open. These floods are believed to have begun as early as 2.6 million years ago, at the onset of the last Ice Age, and ended around 13,000-15,000 years ago. Today, their evidence can be seen along a 600-mile path stretching from western Montana to the Pacific Ocean, with the greatest concentration of flood features in eastern Washington State.

Recently, NPCA, members of Congress, and many others have come together to support national recognition of these cataclysmic events. Senator Maria Cantwell (D-WA) and Representative Doc Hastings (R-WA) introduced legislation supporting the creation of a national geologic trail to be overseen by the National Park Service. Both bills passed and a final bill will soon be sent to the President. If signed, the Ice Age Floods National Geologic Trail would be the first of its kind in the National Park System.
