Long Run-out Landslide (IMAGE) Brown University Caption This 2014 landslide in Mesa County, Colorado contained 30 million cubic meters or rock and ran out for 2.8 miles. New research helps explain how these large slides are able to run out so far. Vibrations within large slides cause them to flow like a fluid.
