Each polygon in this shapefile was created during the georeferencing of its associated aerial photograph. This group of photographs was originally thought to cover the region between Riverside and Yucaipa, California. Georeferencing these photographs determined that only the northernmost portion of Riverside is covered and that the area covered stretches all the way to the Lytle Creek area of the San Bernardino Mountains.

Contains polygons indicating location of each aerial photograph. The index numbers applied to the original photos are used to identify each polygon.
