Burton Hall was built in 1914 as a home for the life sciences, zoology and botany, which later collectively became biological sciences. Burton was originally called Biology Hall and was renamed in 1917 in recognition of Smith's second president, Marion Burton. Part of the Clark Science Center, Burton Hall is now home to the departments of geology and mathematics. Sculptor and mathematician Helaman Ferguson created the sculpture Aperiodic Penrose, which illustrates a mathematical theorem and is part of an outdoor rock garden that flanks the building. Inside, visitors can find cases of fascinating mineral and gemstone displays.
