Black Mountain is located in the border region of Virginia and Kentucky in a landscape ravaged by surface mining. Despite the destruction, R. cumberlandense can still be found there in various places. Coming from Virginia, we drove the VA 160 to its highest point at the Kentucky border. On the other side of the pass this road becomes KY 160. At first we drove northeast for a few km on a dirt road branching off at the pass and running along the state line. Here we found R. cumberlandense in full bloom again and again on the Kentucky side. Then we drove west from the pass along Black Mountain Ridge Road. Here we found some beautiful R. cumberlandense as well at one place.
