A massive rockslide closed a busy interstate route last week near the border between Tennessee and North Carolina in Pigeon River Gorge. This area has had landslide problems in the past.

I have yet to see volume estimates, but The Charlotte Observer quoted a highway patrol officer who was at the scene:

He said the roadway is covered by a gigantic mound of debris, from pebbles up to house-sized boulders. The pile is 40 to 50 feet high, Williamson estimated, and hundreds of feet long.

More info and video after the break. […]
