The Department of Biology, Geology, and Physical Sciences offers degrees in biology, chemistry, and geology, as well as courses in astronomy, physics, and physical science.

Sul Ross State University's location in mountainous West Texas, makes it an ideal locality for geological studies and astronomy.

The campus, surrounded by the Trans-Pecos volcanic field, is only 20 minutes from McDonald Observatory and only two hours from Big Bend National Park and Big Bend Ranch State Park.
