WENATCHEE — The Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will offer its next program Saturday, according to an announcement from the organization.
Dr. Ralph Dawes, Professor of Earth Science, Wenatchee Valley College, will discuss the glaciated landscape that formed beneath the Okanogan Lobe of the Cordilleran Ice Sheet in north-central Washington, according to the announcement. This area, including Douglas County north of Waterville and all of Okanogan County, was studied early in the last century by well-known geologists J. Harlan Bretz, Richard Foster Flint and Aaron C. Waters. How the ice sheet shaped the landscape underneath it was a source of controversy back then, and remains a subject of scientific debate today.
The program is free and open to the public, the announcement said. It begins at 7 p.m. at the Wenatchee Valley Museum and Cultural Center, 127 South Mission St., Wenatchee. Those who would rather attend via Zoom can do so at https://bit.ly/459Qyic.
