Description: Aerial photos were collected in 1931 of Isle Royale National Park (ISRO). These images have been used for many purposes over the years, but were just recently scanned and made digital. The digital images were examined and approximate photo center locations were created to assist during future steps. The images are from the Abrams Aerial Survey Company and are the Isle Royal Aerial Survey cone c. 1931. Prints have been stored at ISRO headquarters. Many of the prints have been used for mapping purposes, some have deep grooves, clearly from using a ball point pen to draw polygons, most likely for a soil mapping project, and several of the prints have ink marks indicating features such as docks, buildings, etc. The grooves are not apparent on the scans. A total of 28 frames were missing from the archive held by ISRO. The original negatives were found to exist at the Archives of Michigan, located in Lansing, Michigan. Scans were requested of these frames, and all but 2 frames were available, and have been scanned, also at 1000dpi.
