During the last Ice Age, the Pacific Northwest was forever shaped by hundreds of cubic miles of water, ice, and debris that repeatedly roared out from huge water bodies, including Glacial Lake Missoula, created by continental ice sheets. Evidence of those floods is particularly abundant throughout eastern Washington’s Mid-Columbia Basin (Figure 1). To begin to fathom the volume and destructive pow

er of the events that shaped the eastern Washington landscape, causes one to examine the relationship between ones self and nature. Less than a century ago no one imagined that some of the most astonishing geologic events ever had taken place in the Pacific Northwest. Today numerous museums, books, magazine articles, professional papers, videos, and science and travel television programs tell the story. The National Park Service has recommended that Congress create an “Ice Age Floods National Geologic Trail” connecting and interpreting significant flood features.

Last weekend we enjoyed some great weather and explored the geology of the Tri-Cities with local geologist and tour leader George Last! Field trip participants got front row seats to roughly 8.5 Million years of geologic history, getting up close with Columbia Basin flood basalts, ancestral river deposits, and ice age flood deposits! Many thanks to all of our field trip participants and volunteers with MCBONES for hosting us at the Coyote Canyon Mammoth Site!

Keep an eye out for future field trip opportunities!
