Beneath Rundel Library, a slowly collapsing catwalk extends from the abandoned subway over the spillway, and visitors are able to approach the spillway arches to get a unique view of the Genesee River. Frozen waters during the winter months make this view especially noteworthy. From the catwalk a ladder extends to the ceiling where a locked access panel is found that assumedly leads to the library or a safehouse for the non-existent Illuminati Catacomb System.
