Climbed Tri-State Peak (and Ft. Foote along the way) and then also took the trail from the gap to Ft. McCook and Ft. Lyon, then over the ridge and down Lewis Hollow. Got an education in the Civil War struggle over Cumberland Gap.
After summitting Black Mountain drove on down to Cumberland Gap NHP for some hiking.
Followed the trail from the Iron Furnace parking area.
What a difference, from 18 F to 30 F, was sweating since I wore the same jacket for both ascents.
