Arizona State College at Flagstaff erected the Physical Sciences building in 1960 and it opened in the spring of 1962 as part of President J. Lawrence Walkup's expansion efforts. Its design reflects the International style, with its concrete construction and lack of ornamentation. The Science and Mathematics departments occupied Old Main, Hanley Hall, and Frier Hall before moving into Physical Sciences. Northern Arizona University constructed the Biology building in 1967 and the Chemistry building in 1968, completing the Science Complex.
All of these buildings, in addition to Liberal Arts, are located on the former Skidmore Field. Physical Sciences currently houses the Center for Environmental Sciences as well as the Department of Physics and Astronomy.
