The latest update: 3:25 pm
I called and spoke with the GSMNP public affairs office. They told me that a rock slide occurred at the "Indian Head" a rock outcropping that overhangs Little River Road below the Sinks. The slide has been cleared but they are unsure of the stability of the rock outcrop.
Until further notice, the Little River Road is CLOSED between the Townsend "Y" and the Metcalf Bottoms Picnic Area. The upper part of Little River and the Elkmont Campground can be accessed through the Wear Cove entrance to the park. (this is in Wears Valley, the road is Lyons Spring Road). Large RV's and heavy vehicles are not permitted through that entrance and will have to access Elkmont via Gatlinburg.
