Black Mtn, KY - Actual Summit Marker (not on HWY 160)
This image is attached to the Black Mountain page, https://www.summitpost.org/black-mountain-ky/153383.
Black Mountain is accessed via HWY 160 (aka Main St in KY, or Inman Road in VA).
The highpoint of HWY 160 is the border of KY/VA, and has a sign which incorrectly lists
Black Mtn elevation as 4,145 ft when really it is 4,139 ft and further up the mountain (to the west) as seen in this photo.
