Great Smoky Mountains Landslide, North Carolina. 2013.

On January 5, 2013, the massive landslide took out a football field-sized portion of Newfound Gap Road (US 441) on the North Carolina side. Approximately 90,000 cubic yards of dirt, rock and roadway crashed 45-50 feet down the side of the mountain. Officials from the Great Smoky Mountains National Park found a subsurface spring underneath the landslide. NPS staff said the spring, along with last week's massive amounts of rainfall, contributed to the landslide Wednesday morning, near mile marker 22 between Collins Creek and Webb Overlook.
