Clinch Mountain in Hawkins County: a large rockslide in Tennessee
This weekend a significant rockslide from Clinch Mountain closed down Highway 70 near to Cave Springs in Hawkins County in Tennessee, USA. Amanda Ketchledge, a reporter from WATE 6 News tweeted the image below of the landslide, taken by Jay Herring:
WBIR has a nice article about the landslide, which includes this aerial image of the rockslide:
The image below appears to be the location on Google Earth. The spot is at 36.5012, -83.0282 if you want to take a look:
From the image above the location looks innocent enough, but the images of the aftermath suggest that this is a classic planar rockslide on pre-existing joints that dip approximately parallel to the slope. This has resulted in the generation of tabular pieces of rock debris. It is of course fortunate that no-one was on the road at this location at the time of the landslide. On Sunday work started to clear the road.
