Science Hill is a precinct of the Yale University campus primarily devoted to physical and biological sciences. It is located in the Prospect Hill neighborhood of New Haven, Connecticut.
Originally a 36-acre residential estate known as Sachem's Wood, it was purchased by the university in 1910 as a land bank. Removed from the main campus and close to the former Sheffield Scientific School, the hill was allocated to large science laboratories and the main buildings of the Yale School of Forestry & Environmental Studies. Several laboratory buildings were completed in the 1910s, but most of the campus was completed during the build-up of scientific research after World War II.
The topography of present-day Science Hill was primarily formed during the Wisconsinan glaciation. The Laurentide ice sheet flattened the soft sandstone of New Haven Harbor but had less effect on its surrounding, hard trap rock formations like East Rock and West Rock. Science Hill is a portion of a sandstone drumlin that was sheltered from glacial erosion by a traprock ridge, Mill Rock, to its north. The south–north rise of Science Hill is approximately 80 feet (24 m) at a 4.5% grade, processing northward to a peak elevation of 150 feet (46 m) above sea level near the Yale Divinity School.
