Near Washtucna in Franklin County, Washington — The American West (Northwest)
Setting the Stage
Millions of years later, Ice Age floods swept through this area. The floodwaters took advantage of these fractures, cutting steep chanels where the bedrock was weakest and creating Palouse Falls and its canyon. The floods also changed the course of the river.

During the height of the floods, this entire area was under hundreds of feet of water. This painting shows a flood in progress after the water level dropped several hundred feet.

See the large crack in the basalt cliffs across the canyon? This is one of the fractures in the basalt opened by tectonic forces coming from deep within the earth. Can you see any others?
