Inscription.  The raised areas you see around the village are midden mounds or earthen mounds ranging from one to ten feet high. There are more than 30 mounds surrounding the village. The Mandans at Double Ditch disposed of their trash in heaps such as the one in front of you. The oldest mounds, dating to AD 1550-1650, occur directly atop Ditches 3 and 4. Excavations showed some mounds to be accumulations of household refuse-animal bones, broken pottery, and ash from hearths-carried and dumped in huge heaps. Other mounds were composed partially or entirely of fill excavated from elsewhere in the village, clearly indicating that those mounds were intentionally constructed. The mounds provide one of several kinds of evidence for large scale earthmoving.

During one phase of occupation, the village defense involved a combination of Ditch 2, which lacked bastions, and several large mounds placed as strong points just inside the ditch. Mound B was built rapidly from borrowed fill, and its construction ceased just when ditch 2 was excavated.
