The Geoarchaeological Context of Grand Island

Abstract

Interpretations of the geoarchaeological context of Grand Island, Michigan have been a critical part of prehistoric archaeological investigations. Geoarchaeological investigations have generally focused on determining the age of various geomorphic surfaces, interpreting site settings, and paleoenvironmental reconstructions. Although no Paleoindian materials have yet been found, the island was available for human occupation following final deglaciation sometime after 13,000 cal b.p. High lake levels during the Nipissing Phase (ca. 5700–4450 cal B.P.) built a series of coastal landforms that where heavily used by Archaic Period people. Post-Nipissing fluctuations in lake levels presented a highly variable coastal setting for Terminal Archaic and Woodland Period people
