Among some of the more interesting things I find on this photograph is that Cedar Beach is still a swimming hole, the pool has yet to be built. The 15th Street Bridge has yet to be built. The former quarry just south of Union Terrace is quite prominent, and the train spur going through the area is visible. The racetrack at the fairgrounds is very identifiable, as is the half circle driveway at Muhlenberg College. This aerial photograph is from 1939. Click on photo to enlarge.
