Bridgeton 23SL442

The Bridgeton archaeological site (23SL442) was a large village site on a terrace above the Missouri River.



Plan of a Mississippian house (number 10) that was rebuilt four times. The original footprint of the house measured 6.0 x 3.6 meters. The final phase of the house measured 8.0 x 3.8 meters. Pit feature 134 contained Emergent Mississippian pottery sherds. The house was warmed by a central fire hearth. The floor of this structure contained portions of two Busycon shells and fragments of mica.

Drawing of a Ramey Incised vessel found in house number 1 at the Bridgeton Site.




A human effigy head (out of clay) was discsovered in house number 1. The head was attrached to the rim of a bowl so that it faced towards the center of the bowl. Discovered during the 1982 field season; registration number 1524. The fragment measures 39.8 mm in height and 29.6 mm in width. The fragment weighs 30.8 grams and is very pale brown (10YR7/4) in color.

The University of Missouri - St. Louis conducted several summer fieldschools at the site during the 1980s under the direction of Joe Harl; he analyzed the data as the basis of his Master's thesis at Washington University in St. Louis. Four wall trench houses were identified as a result of the UMSL excavation. Additional fieldwork was conducted at the site during 1999 by SCI Engineering, Inc., St. Peters, Mo. Soil fill removal and subsequent construction projects have destroyed the important site.

The digital photographs of the pottery sherds from the site were taken with the permission of Joe Harl during a meeting of the Missouri Archaeological Society. The digital photographs of the arrowpoints and shark tooth were taken with permission of John Crowley, President of the Central States Archaeological Societies.
