Landslides are rare features in Tennessee and are restricted to very steep mountainous terrains that have unstable bedrock formations. In Great Smoky Mountains National Park, the extremely steep slopes of Mt. LeConte are developed on very loose and slide-prone slate formations of the Anakeesta formation. Periodically during heavy rains or perhaps triggered by occasional small earthquakes, large sections of mountain slope give way. The result is the formation of long, narrow landslide scars that leave behind steep, rocky slide zones. These slide zones are re-colonized by plants that occur on nearby rock outcrop communities and include a number of rare, high-elevation species.
