Mount Kephart is a 6,217-foot peak in the central Great Smoky Mountains on the Tennessee–North Carolina border, prominent to hikers because the Appalachian Trail crosses its south slope near Icewater Spring and the Jumpoff overlook. Its upper elevations support Southern Appalachian spruce-fir forest, while its bedrock belongs to ancient ocean sediments later uplifted in the Appalachian mountain-building episode. The mountain was renamed in 1931 for Horace Kephart, an early advocate for a Smokies national park. Its slopes also hold traces of the 1930s park-building era, including a Civilian Conservation Corps camp, later used during World War II, and the remains of a Works Progress Administration fish hatchery.
