The Cache County aerial photograph collection consists of high-altitude images probably taken in 1952 and 1959 by the Aerial Photography Field Office in Salt Lake City. There are also images from Oneida and Franklin County on the Utah/Idaho border and along the Cache/Box Elder County and the Cache/Weber County boundaries. These images are from 9" x 9" negatives and taken at 1:20,000. The date the image was taken is usually in the upper left-hand corner.
