Glacial history of the Pacific Northwest

WENATCHEE - The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute is set to host a presentation on the glacial history of the Pacific Northwest on Tuesday, August 13. The event will take place at 7:00 p.m. at the Wenatchee Valley Museum and Cultural Center, with a virtual option available via Zoom.

Daniel Coe, graphics editor for the Washington Geological Survey in Olympia and editor for the North American Cartographic Information Society's Atlas of Design, will deliver a talk titled "Mapping the Glacial Legacy of the Pacific Northwest."

Coe's presentation will explore how glaciers have shaped the region's landscape over the past 15,000 years, focusing on the impacts of the Cordilleran ice sheet, repeated ice age floods, and extensive alpine glaciation. The talk will showcase both historical and modern maps, illustrating the evolution of glacial landform mapping and interpretation since the late 19th century.

The Washington Geological Survey's recent efforts in creating new maps will be highlighted, demonstrating how traditional datasets and techniques are being combined with modern insights and technologies such as lidar to enhance our understanding of the area's glacial history.

The event is free and open to the public. Interested parties can attend in person or join via the provided Zoom link at https://us02web.zoom.us/j/84520197937. For more information on this and other Ice Age Floods Institute programs, visit their official website at iafi.org.
