Colliding continents, volcanic eruptions, and lava flows
have shaped the landscape of Washington and Oregon over the
last few million years. However, in recent geologic time the
most dramatic geologic events in the region may have been
the Missoula Floods. The Missoula Floods were giant ice age
floods that traveled at over 90 miles per hour from Montana
to the Pacific Ocean and covered the land with over 400 feet
of floodwater. The floods were so powerful that they moved
mountains, destroyed everything in their path, and transported
the rich soil of eastern Washington to the Willamette Valley.
