Lone Mountain is located on the western fringe of the
Crab Orchard Mountains, the southern tip of the
Cumberland Mountains which rise atop the
Cumberland Plateau just west of the plateau's
Walden Ridge escarpment. The mountain's western base is formed by the
Emory River, which flows down from its source near the summit of Bird Mountain to the northeast and winds around the base of the range before descending the plateau and emptying into the
Watts Bar Lake impoundment of the
Tennessee River. Lone Mountain's northern base is formed by Crooked Fork, a tributary of the Emory. Bitter Creek, which flows roughly parallel to the Emory, slices a substantial valley along Lone Mountain's eastern base, splitting the mountain off from the rest of the Crab Orchard range. Lone Mountain spans much of the stretch of
U.S. Route 27 between
Harriman and
Wartburg. The community of Mossy Grove is situated at the mountain's eastern base in the Bitter Creek valley. ==History==
