Planar rock slide on Highway 70 in Hawkins County

As Dr. Petley noted in his blog post, this looks like a classic planar rock slide where the rock mass failed parallel to the dominant planar discontinuity set. The slide occurred on Highway 70 between SR 94 and Clinch Valley Road. It will take the better part of a week to clear the debris according to TDOT. [Source: The Landslide Blog – AGU Blogosphere.
