    Social change and late Holocene hydroclimate variability in southwest Indiana
    (Elsevier, 2023-03) Krus, Anthony M.; Herrmann, Edward W.; Friberg, Christina M.; Bird, Broxton W.; Wilson, Jeremy J.; Anthropology, School of Liberal Arts
    The archaeology of how communities in the North American midcontinent responded to environmental change has had global significance for understanding hydroclimate-human relationships in non-industrialized societies. We evaluate how an agriculturalist settlement network, the Angel polity, coped with environmental change through comparing the radiocarbon-derived occupation history to local proxies for hydroclimatic change from Martin Lake, Indiana. Located within the northeast Mississippian (AD 1000–1500) frontier, the Angel polity consisted of a network of hamlets and villages, encompassing ∼800 km2 in southwest Indiana with the Angel Mounds site serving as the polity’s social nexus. The results indicate that Angel Mounds was established as the Medieval Climate Anomaly transitioned to Little Ice Age (LIA) drought with the construction of a community centered around a platform mound earthwork. The Angel polity’s population became more centralized at Angel Mounds during the initial decades of the LIA drought conditions and a large fortification was constructed at Angel Mounds during this time. The dissolution of the Angel polity occurred in AD 1350–1450 during a profound LIA-associated mega-drought and regional depopulation of the midcontinent. These results provide an example of how non-industrialized, agriculturalist communities responded to episodes of hydroclimatic change.

    Star Bridge: A Late Mississippian Village in the Central Illinois River Valley
    (2020-08) Flood, John Scott; Wilson, Jeremy J.; Herrmann, Edward W.; Mullins, Paul R.
    The late pre-Columbian period in the central Illinois River valley (CIRV) is demarcated by the development of large, often-fortified Mississippian towns, farming hamlets, extensive trade networks, and shifting political alliances between AD 1050 and 1450. The fission and fusion of local polities ceased with abrupt abandonment of the CIRV by AD 1450 as part of the larger Vacant Quarter phenomenon. Located on a hypothesized boundary between Mississippian and Oneota zones of socio-political influence during the 14th century, Star Bridge (11Br17) was a Mississippian village previously believed to have been incinerated during an assault. Through the analysis of an avocational surface collection, a 1992 excavation assemblage, and recent geophysical investigations, my research re-examines Star Bridge and assesses the site’s integrity after decades of agricultural modification. Geophysical data and the material culture from excavations suggest Star Bridge never burned but was abandoned after one or two generations of occupation shortly before the exodus of Mississippian and Oneota groups from the CIRV. Meanwhile, my analyses also revealed a dearth of Oneota-derived or influenced material culture, indicating a dearth of interaction between Star Bridge’s inhabitants and their neighbors upstream. Instead, the material culture suggests Star Bridge was part of a string of late 13th and 14th century villages known as the La Moine River polity.
