Corfu Slide

The Corfu Slide is a geologic feature located on the north slope of the Saddle Mountains near the Columbia river in eastern Washington. It covers aproximately 13 square kilometers and contains a volume of material of about 1 cubic kilometer. It is thought to have occured 13,000 to 15,000 years ago as the result of undercutting which occurred during the Missoula Floods associated with the retreat of glaicers during the last ice age.
