2009 Little Frog Mountain landslide
The 2009 Little Frog Mountain landslide occurred on November 10, 2009 in Polk County, Tennessee, near Ducktown. The event was likely the result of the 2009 Southeastern United States floods, when many parts of the southern Appalachian Mountains became saturated.[1][2] The landslide was essentially a rockslide, and made U.S. Route 64/74 impassable for several months.[3][4]
This section of U.S. Route 64 is known as the Ocoee Scenic Byway and generally follows the Ocoee River. The landslide happened just west of Ocoee Dam No. 2,[5] when a large piece of Little Frog Mountain (a foothill of Big Frog Mountain) became unstable.[6][7] The rockslide was captured in a dramatic video, which aired on many local and national television news outlets.[8][9][10][11]
