The collection consists of 525 color slides that contain mostly aerial views of Fairfax County and Loudoun County, Virginia. The aerial views feature housing developments, automobile transportation corridors, Dulles International Airport, and the surrounding countryside. Many of the photographs at ground level feature the contested area at the intersection of Old Dominion Drive (Route 738) and Spring Hil Road (Route 684) that was the subject of a lawsuit between Mobil Oil and the Fairfax County government. In 1986 Mobil requested that the area be rezoned, and eventually succeeded after multiple appeals. There are also slides with charts and graphs, perhaps used for presentations. Some of the slides are individually identified with handwritten titles, and the titles follow the naming conventions used on the original slide boxes with some editing for clarification. The photographs of Loudoun County are mostly aerial photographs of Leesburg, Middleburg, and various interchanges in the county. There are several images of farms and the surrounding countryside.
