The Pacific Northwest looks normal because we are used to it.
The Columbia River Gorge, The Dalles, Eastern Washington, Portland, Lake Oswego, the Willamette Valley. It all just feels like the landscape we happen to live in.
Then you learn about the Missoula Floods and realize a lot of this place was shaped by repeated Ice Age mega floods that tore through the region with enough force to rearrange the map.
In this episode of Maxwell’s Kitchen, I talk with geologist Scott Burns about the Missoula Floods, Glacial Lake Missoula, J Harlen Bretz, the Channel Scablands, Portland geology, ice-rafted boulders, the Willamette Meteorite, Ice Age animals, wine terroir, climate change, and how to read the landscape around us.
Scott is Professor Emeritus of Geology at Portland State University and co-author of Cataclysms on the Columbia: The Great Missoula Floods.
We talk about how an ice dam created Glacial Lake Missoula, how the dam failed, why the floods repeated many times, and how geologists figured out what happened by reading the land. Scott also explains how the floods shaped Oregon and Washington, including the Columbia River Gorge, The Dalles, Portland, Lake Oswego, Tualatin, and the Willamette Valley.
This conversation also gets into mastodons, mammoths, saber-toothed cats, giant beavers, the Willamette Meteorite, Mount Hood, Mount St. Helens, radiocarbon dating, radiometric dating, wine soils, climate change, glaciers, sea level rise, and nuclear power.
