I found patches of Appalachian White Snakeroot (Ageratina roanensis or A. altissima var. roanensis, depending on your authority), a mystery goldenrod at the Little Pinnacle summit, a mystery whorled composite, and a mystery bryophyte.
A younger me would have tried the walk from Big Pinnacle to Massie Gap, but the prudent present me drove back to Massie Gap for an afternoon loop that used about 3/4 mile of the Appalachian Trail along Wilburn RIdge. I walked the Maine-bound direction; I wasn’t overtaken by any spry through-hikers, but there were some folks to say hello to going the other direction. The AT here is fairly level, a rhododendron thicket with random unmarked side trails and more spruce.
Some fairly large vaccinium shrubs. About 85 meters of elevation change, 2:20 for the loop.
