The 2011 UWM Archaeological Field School at Aztalan

Aztalan site location and plan of 2011 excavations

Excavation of Test Unit 2 exposed a 3.7 m long X 2.4 m deep standing profile in the bank of a ravine eroding into the Crawfish River. Colluvial re-deposition of upslope sediments containing aboriginal debris dating to the Mississippian settlement of Aztalan overlays a massive deposit of aboriginal “buckshot” fill. The filling episode may have been an attempt to construct a level platform-and-post structure in order to enclose the running water of the Crawfish River within the palisade. Alternatively, the ravine may have been filled to increase the amount of habitable land within the residential area of the site
