Spectacular floods radically changed the landscape of the Pacific Northwest some 17,000 years ago when ice age glacial dams near Missoula, Montana broke apart and unleashed an inland sea. Geologists believe this powerful flood was the greatest moving body of water in the Earth's history. This program helps students undertand how geography can provide clues to the distant geologic history of an area.
