Many thanks to Bob, Bill, Sam and Wayne whose replies were so helpful. I was finally able to find it on the De Lorme map where the "Bull Run" name now appears in two of the southern fingers of Smith Mountain Lake. The lat-long position given in the _Omni Gazeteer_, Volume 3: "Bull Run, stream, Franklin Co., USGS "Moneta SW", 370159N-0793731W". Marilyn Symonds
