The campus is roughly divided into "uphill" and "downhill" areas by a large slope between Moore Avenue and Dent Drive. The uphill area flanks U.S. Route 15 and the West Branch Susquehanna River and features many of the academic buildings, including the main academic quadrangle, the Observatory, and library as well as some dormitories, Christy Mathewson–Memorial Stadium, and Fraternity Road. Downhill borders the Victorian-era neighborhoods of downtown Lewisburg and features mainly residential buildings, including the majority of first-year dormitories, the Gateway apartment complex, the President's house, many of the indoor athletic facilities, and Hunt Hall, home to the school's sororities. Bucknell West, which is separated from the rest of campus by Route 15, features some housing, athletic fields, art and psychology/animal behavior laboratories, and an 18-hole golf course.
