A nice story about the development of the catastrophic-flood theory to explain all the geographical oddities prevalent in Eastern Washington. The photographs accompanying the story are the most thorough I've ever seen.

The Scablands are essentially wounds, still unhealed by time and erosion. They cut through the land and down into the rock after a series of unfathomably large floods unleashed by the catastrophic draining of great glacial lakes—half the volume of Lake Michigan splashed onto the land in less than a week. If you can imagine that, you’ve got us beat. The story recorded in this landscape is so incredible, it took one geologist decades to convince his colleagues that he was reading it correctly.
