This collection of slides documents significant naturalist and structural features of the Fairmount Park system. It extends beyond the watershed parks to include many neighborhood parks, sculptures and fountains, major events and activities, and the greater Philadelphia area. A limited number of map and graphic images stored in slide form are included, as well as a few presentations and analyses projects.

The majority of the collection is categorized alphabetically according to identifiable landmark and stored in a nine-binder set. Sculpture and fountain images are contained in an individual binder due to relativity of content. Images relating to graffiti in the park have been divided into one binder, regardless of location. General park features, bridges, and activities which were not identifiable have been separated and stored in box form, as have slides relating to the Fairmount Water Works due to the large amount of slides available on that topic.

Two slide shows have been stored in individual carousel containers to preserve their provenance- one contains information on the Schuylkill River Heritage area, and one on historic park houses. Additionally, two analyses have been stored in individual slide cases for the same reason, and they concern an analysis of the Belmont Plateau and an analysis of Kelly Pool.
