The site once consisted of four mounds, several flat-topped platform mounds and at least one burial mounds and extensive midden areas. The site was excavated by Edward Palmer in 1883. He described the largest two platform mounds as being 4 metres (13 ft) in height and 3 metres (9.8 ft). He also noted a 2.4 metres (7.9 ft) burial mound and a low mound of undetermined function. Only the largest platform mound survives to the present day. This mound was tested in 1988 and 1994, and returned dates between 730 and 1010 CE.[1]
