Ice Age Floods National Geologic Trail information
Network of routes connecting natural sites
Glacial Lake Columbia (west) and Glacial Lake Missoula (east) are shown south of the Cordilleran Ice Sheet. The areas inundated in the Columbia and Missoula floods are shown in red.
The Ice Age Floods National Geologic Trail is a network of routes connecting natural sites and facilities that provide interpretation of the geological consequences of the Glacial Lake Missoula floods of the last glacial period that occurred about 18,000 to 15,000 years ago. It includes sites in Washington, Oregon, Idaho, and Montana. It was designated as the first National Geologic Trail in the United States in 2009.
