From Stepps Gap one can also take the gravel road around Gibbes mountain and approach from the col between Gibbes and the fenced-in Clingman's Peak. There are great views to the northwest from the road to what's known as the Bearwallow Stand Ridge.
Once at the col, take a disused jeep trail to the summit, bushwhacking the last 0.1 miles or so.
... on the "Black Mountains" SP Area/Ranges page.
Thanks for the suggestion. I have attached both Hallback and Gibbes to the Black Mountains page.
