A road crew and a television crew were on the scene on Highway 64 in Polk County, Tennessee Tuesday when a massive rock slide covered the road. Workers were busy removing a large rock that fell Tuesday morning when the mountain gave away at about 1PM. Rock slides are not uncommon in the mountain area of East Tennessee, but they are rarely seen in progress, much less recorded. The road will be closed for at least a week. Link
Cool video. I wondered why we weren't hearing people whooping and swearing - just the sound of the rocks sliding.
