From Derrick Knob we hiked a bit more on AT (Northbound) and then started walking down on Miry Ridge trail to Marks Cove,  11 km and 800 m total elevation gain. Next day 13 km was all downhill to Tremont. We took lunch break at Indian Flat Falls.
Indian Flat Falls
And enjoyed easy walk on old forest road through the forest and along Middle Prong Little River with many cascades and falls. For a while we walked in quite heavy rain, but we were already on paved Upper Tremont Road so it was not too bad. We found our car at West Prong trailhead as we left it. We packed our still somewhat wet gear and after big dinner in Townsend took off for Chicago with  O/N near Knoxville.
