The Corfu Slide is a geological feature located on the north slope of the Saddle Mountains near the Columbia river in eastern Washington. It consists of 24 separate slides that cover approximately 18-20 square kilometers (7 to 8 miles²)[1] and contains a volume of material of about 1 cubic kilometer. It is thought to have occurred 13,000 to 15,000 years ago as the result of undercutting which occurred during the Missoula Floods associated with the retreat of glaciers during the last ice age. At least some of the slide occurred before the final Missoula Floods as the older landslide debris has been eroded and smoothed by water flow.[2][3]
The best viewpoint for the landslide is from its top on the crest of the Saddle Mountains. However it is visible from a number of points, including a road which traverses the lower portions of the slide. [3]
