The Treaties of Hopewell established the boundary between the U. S. and the Cherokee and Chickasaw as the ridge dividing waters flowing into the Cumberland from those flowing into the Tennessee, and in separate treaties signed at Hopewell, South Carolina, the Cherokee on November 28, 1785, and the Chickasaw on January 10, 1786, ceded the land north of this ridge to the U.S. Today known as Duck River Ridge, the ridge here runs roughly along the same path as Natchez Trace Road, and its crest remained the boundary until 1805, when new treaties signed by the Chickasaw on July 23 and by the Cherokee on October 25 moved the boundary farther south. During the 20 years when the top of this ridge formed the boundary of the U. S., the Chickasaw, by treaty dated October 24, 1801, granted the U. S. the right to build a wagon road through Chickasaw territory to Natchez, Mississippi, making the original entry point of the Natchez Trace into Chickasaw territory near this location. West of here, Smarden Post Office operated from 1903 to 1906 in Jim Carlisle's store on Old Natchez Trace Road, and when the Middle Tennessee Railroad crossed the ridge in 1909, a steam shovel operator named Mobley gave his name to the geographic feature known as Mobley's Cut. Area families included Davis, Beard, Holt, Walls, Skelley, Parham, Sudberry, Carlisle, Lynn, Griggs, McCandless, Fox, Smith, Johnson, Goodgine, Turman, and Hargrove.
