The 1999 Ball State University archaeological field school was held at the Anderson Mounds complex located in Mounds State Park and the New Castle complex. These two sites represent the best preserved Middle Woodland earthwork complexes in east central Indiana. Limited excavations were conducted at several of the earthworks at Anderson Mounds and one habitation site. Investigations at New Castle re-opened areas previously excavated to expose intact profiles in Mound 4. Information concerning artifact types, radiocarbon dates and construction of the earthworks were recovered.
