  1. Cahokia

  2. Cahokia • Site location: • 16 km east-northeast of Saint Louis (in East Saint Louis), On Cahokia Creek • Cahokia was the largest prehistoric city north of Mexico • At its peak it may have had some 20,000-30,000 inhabitants • Appears to have been the center of at least 50 communities in the American Bottom region

  3. Occupation • This site was first inhabited by Indians of the Late Woodland culture about AD 700. • The site grew during the following Mississippian period, after AD 900, and by AD 1050-1150, the Cahokia site was the regional center for the Mississippian culture with many satellite communities, villages and farmsteads around it. • After AD 1200, the population began to decline and the site was abandoned by AD 1400. http://www.nps.gov/history/worldheritage/cahokia.htm

  6. City Center • Site center is basically diamond shaped with an interior palisaded core • 4.58 km east-west by 3.67 km north-south and 13.4 km2 • 120 mounds • City center: • Monk's Mound plus 16 other mounds • Basically shaped like a squat boat heading south • Surrounded by a palisade on three sides (Cahokia Creek defining the fourth side) • Majority of mounds lie outside the palisaded inner core • One small mound yielded the burial of a high-ranking individual buried with: Caches of arrow heads, Polished stone, Mica, Six sacrificed male retainers, A separate mass grave containing 53 women

  7. Palisade • Excavations begun in 1966 uncovered a two-mile-long stockade surrounding the central portion of Cahokia. • The wall was started around A.D. 1100 and then rebuilt three times over a period of 200 years. • Each construction required 15,000-20,000 oak and hickory logs, one foot in diameter and twenty feet tall. • The logs were sunk into a trench four to five feet deep and were supported with horizontal poles or interwoven with saplings.

  8. Reconstructed Palisade

  9. “Woodhenge” • Evidence that there were as many as five Woodhenges. • These were built over a period of 200 years (A.D. 900-1100). • Fragments of wood were identified as red cedar and used for the posts.

  10. "Woodhenge“ Functions • Possible functions of "Woodhenge“: • Observatory (?): May have functioned like Stonehenge as a sort of "observatory" • For astral and horizon alignment observations. • three posts are crucial as seasonal markers -- those marking the first days of winter and summer (the solstices), and one halfway between marking the first days of spring and fall (the equinoxes). • Sun Dance "Temple" (?)

(6.4 hectares) • 316 by 241 meters(76156 square meters) rising over 30 meters high • Contains over 600,000 cubic meters of earth • Constructed in stages • This constitutes one of the largest examples of prehistoric construction in the entire Western Hemisphere
