Fanrock is an unincorporated community in Wyoming County, West Virginia, United States. Fanrock was home to one of the most unusual airports in the United States. Swope Farm Airfield was a private airfield on a hillside of W.O. Swope's farm. It had a slope of 11% and it was sharply curved at the high end. It was only 1250 feet long, which made takeoffs and landings extremely difficult. The airfield has fallen into disuse in recent years.
