Mystery of the Megaflood

The "Mystery of the Megaflood," a documentary watched in lab, is an interesting phenomenon that has stumped scientists for many years. This takes place over the Scablands, which have changed gradually over time to form many different and unique formations. The question scientists want to know is how did these phenomenons occur? For many years scientists believed the Scablands were formed by erosion. Another theory that has caught rise is the theory of a giant powerful flood that occurred about 15,000 years ago. Formations like the Devil's Postpile (Picture 1) and Palouse River Canyon (Picture 2) were formed through the power of the megaflood and the chemical reactions that occurred because of it.
