We at the Washington Geological Survey just released an ESRI Story Map about the ice age floods in Washington. The Story Map, entitled Washington’s Ice Age Floods, is included on our new glacial geology webpage. Check them out!
We’ve built lots of new interactive content about glaciers on our new webpage. Learn about glacial landforms, climate, parts of a glacier, glacial lakes, ice age floods, and more.
Washington’s Ice Age Floods Story Map
The Washington Ice Age Floods Story Map tells the story of cataclysmic outburst floods that shaped the landscape of the Pacific Northwest during the last ice age. With imagery, maps and video, this story map follows the devastating deluge of the Missoula floods as it tore across the landscape, from its origins in western Montana to its terminus at the Pacific Ocean. Sites along the Ice Age Floods National Geologic Trail are featured, with an emphasis on flood features in Washington State.
The story map is best viewed on a desktop or laptop computer. Mobile devices will not show all of the content. Navigate by scrolling your mouse through the slides. A few of the animated sections may take a second or two to load during the first viewing.
Near the end of the module there is an interactive map of the Ice Age Floods National Geologic Trail, which includes featured sites in Washington, Montana, Idaho, and Oregon.
