Ancient Massive Missoula Floods

2018 West, Road Trip, Washington

Today we returned to Dry Falls. In 2008 we stopped here just because we spotted the Brown Sign and it was then that we began to learn about the Missoula Floods, the series of catastrophic floods that occurred during the Last Ice Age and so dramatically sculpted the Washington State landscape. Even as we were driving from Grand Coulee to Dry Falls along the shore of Banks Lake, we were noticing the basalt, the result of lava flows from 6 million to 17 million years ago that was the substrate that the ice age floods carved. It was a beautiful drive and we learned even more at the interpretive center.
