Ice Age Floods National Geologic Trail
Ice Age Floods National Geologic Trail is part of the National Trails System. It is not a park unit.
At the end of the last Ice Age, 18,000 to 15,000 years ago, an ice dam in northern Idaho created Glacial Lake Missoula stretching 3,000 square miles around Missoula, Montana. The dam burst and released flood waters across Washington, down the Columbia River into Oregon before reaching the Pacific Ocean. The Ice Age Floods forever changed the lives and landscape of the Pacific Northwest.

Distances are approximate. Wilderness Atlas publishes a center point and an acreage for each area rather than a boundary, so each area is treated here as a circle of the same size and the figure is the gap to that circle.
