The excavations yielded features,
prehistoric artifacts, animal bone, and plant remains. The Havana Culture was thought to be a local variant of the main Middle Woodland, which was dominated by the
Adena and
Hopewell cultures of the
Mississippi and
Ohio River Valleys. Middle Woodland cultures are characterized by their large
burial mounds, some of which are still visible today; as well as their distinctive pottery forms, ceremonial practices,
agricultural activities, and widespread
trade networks. It has also been noted at the Anker and Boumanville sites near
Chicago, Illinois, and the
Fifield Site in
Indiana. Anker, and Hoxie Farm sites and
Schwerdt in southwestern
Michigan where it is part of the Berrien Phase. At the Oak Forest Site, this ware has been associated with early
Historic artifacts, which indicates the pottery was still being made at the time of
European contact. The exact cultural affiliation has not been determined but it has been suggested that the makers of this pottery may be the
Miami or
Potawatomi tribe. This pottery is characterized by shell tempering, predominantly smooth surfaces either plain or decorated by fine vertical incised lines, excurved or flared rims, and often fine notching on the lip. Strap handles or loops are present on some vessels. Some of the
Upper Mississippian vessels found at Griesmer are identified as coranders based on sherds with holes in them. Coranders are a very rare vessel form in the area. Most of these sherds came from Huber ware. Miniature vessels are also present at Griesmer, and most of them appear to be Huber ware as well. Four specific types of Huber ware were identified at Griesmer: • Huber plain (2 vessels) – characterized by plain smooth surfaces with notched lips being the only decoration. • Huber cordmarked (4 vessels) – characterized by
cordmarked shoulder and body and notched or
cordmarked lip. This type is very similar to Fisher Cordmarked except for small details in the manufacture and appearance of the cordmarked surfaces, and the fact that Huber Cordmarked surfaces are more often smoothed-over. • Huber trailed (12 vessels) – characterized by smooth surfaces with fine trailed or incised lines. The lines most often vertical or slant to the right. • Huber bold – this type was identified only on the basis of body sherds, none of them which could be matched to a rim. The lines are finger-trailed and mostly appear to have been applied vertically. == Significance ==
