The Old Industrial Park has many abandoned departments such as a pantry, a sewage department and huge tubes that possibly carried water supply throughout the facility.

There is also a cilinder object with a skull possibly hinting signs of radioactivity and in general, there are leave-less tress, rocks and cars scattered everywhere. Marceline's hobo camp is also situated in this park.
