Facilities & Resources

Our facilities and resources are top-notch.

Facilities

The Earth and Environmental Sciences department is housed inside the impressive Charles H. Townes Science Center. The center is L.E.E.D. gold-certified and includes a number of sustainable features, including chilled beams that use cold water for cooling, low-flow hoods throughout the building, and treated wastewater for flushing toilets. Our department has its own state-of-the-art laboratory facilities, and our students enjoy access to additional labs in the Biology and Chemistry departments.

Charles H. Townes Science Center

The facilities of the Townes Science Center are state-of-the-art and innovative. You’ll find research laboratories designed especially for watershed science, biogeochemistry, geographic information systems, geology, and hydrogeology. Computer labs and multimedia classrooms fill the 200,000-square-foot complex.

Rock and Botanical Garden

The Rock and Botanical Garden that surrounds the Charles H. Townes Science Center is designed to reflect the geology of the Southern Appalachian region. This teaching tool provides aesthetic beauty and research opportunities for those who major in our department. The garden showcases large rock specimens collected from southeast mines.
