1977 Map of Thoroughfare Gap

About this map

Bull Run and Broad Run carve through the foothills of the Mountains in this late-1970s orthophotoquad, documenting the landscape of Prince William and Fauquier counties. The aerial imagery captures the area at a transitional moment, showing the historical footprint of Haymarket and Buckland alongside emerging development. The significant geographic break at Thoroughfare Gap serves as a focal point for transportation and water drainage, while Lake Manassas and Silver Lake appear as prominent features in the eastern half of the survey. The orthophoto format provides an authentic visual of land use patterns, from the clustered crossroads at Antioch to the rural expanses near New Baltimore and the smaller settlement of Thoroughfare.
