Located in oak savanna with 23 m eddy covariance tower. Fairly flat area. Soils are a red sandy clay loam with a clay hardpan located around 30-40 cm. Bedrock typically found at around a meter, rocky outcrops observed around footprint. Very small to no organic layer. Red soils were very dry during calibration with some moisture in the clay hardpan. http://ameriflux.ornl.gov/fullsiteinfo.php?sid=29
