The Blue Ridge Mountains were a mountain range somewhere south of Washington DC. One of Dr. James Zanasiu's potential bridge coordinates landed in them. James Zanasiu Jr, Malte Kerzach, and Florence Brennan reached the bridge coordinates, despite setbacks from local wildlife and Agent Pomson, but the coordinates turned out to be incorrect.
