The Two buildings adjacent to the Lodge contain laboratory and general work space. A house trailer installed by the Academy of Natural Sciences of Philadelphia in 1971, and subsequently donated to the Sanctuary, is subdivided into several small research spaces, including a wet laboratory with hood, refrigerators and small growth chambers.  The second floor of the original Carriage House has been remodeled to include a small lecture room/laboratory and a separate air-conditioned room for computers and delicate equipment. During Lehigh's summer research program, a microcomputer LAN is installed with several PC's, printers, and internet access. The first floor of the Carriage House is used principally as a lecture hall (seating up to 150) for Sanctuary programs. It also contains a small gift shop, as well as two walk-in environmental chambers used by Lehigh researchers. The living room in the Lodge provides a cheerful setting, especially on cool evenings with a fire in the fireplace, for discussions or seminars. It seats up to 20 or so people. The Lodge has a large screened in porch furnished with benches and long worktables, often used by visiting field courses. The Sanctuary maintains several rowboats as well as a couple of canoes on the lake. Lehigh has a fiberglass Boston Whaler equipped with an electric outboard motor.
