Brue Bjornstad has loved rocks since he was a kid, growing up on the East Coast. But his real love and expertise is the Missoula Floods – cataclysmic events that scoured the Columbia Basin, and laid thick deposits of sediments in other areas, washing all the way down the Columbia Gorge and out to the Pacific. These floods also shaped the Hanford area. The lava flows and uplifted mountains also still drive how clean up proceeds at the Hanford nuclear reservation. Bjornstad gives us a geologic tour from an outlook on the White Bluffs overlooking the Columbia River and Hanford.
