OCOEE, Tenn. ? The third major rock slide in four years along U.S. Highway 64 is leaving Polk County somewhere between a rock and a hard place.

Boulders came crashing down near Madden Branch and state Route 30 on Wednesday evening, closing U.S. 64, the main road through the southern part of the Cherokee National Forest. The slide is in the same area where a November 2009 rock fall stranded Polk County residents for months. Getting around it involves a draining 81-mile detour using U.S. 411 and state Route 68.
