The collection consists of geological maps, aerial photographs, and mining and geology publications collected by Fockler during the course of his career as a consulting geologist. The collection also contains material relating to a mineral exploration in northern Quebec that Fockler was involved with in the 1940s.

The collection is arranged into five series: Air photos of northern Ontario and Quebec; Air photos of Ontario highways; Geological maps; Mining and geology publications; New Quebec mineral exploration project.

Collection contains aerial survey photographs primarily of the North Bay area, often with accompanying flightline maps. Photographs organized by year and source.

Collection is made of 86 images from the Forest Resources Inventory (FRI) series, created by the Ministry of Natural Resources. The dates of the images range from 1946-1970. These images are of the North Bay area.

For certain years or flight lines, only every second image is present, which provides complete ground coverage but does not allow for stereo viewing.
