Abstract
To predict undiscovered archaeological sites in the Lower Grand River, we mapped known archaeological sites using color and infrared aerial photos, digital raster graphics, and digital elevation models. We interpreted the geomorphic settings of each site using this preliminary geographic information system. We found both spatial and temporal patterns in site location. The Lower Grand River Valley is cut into Quaternary glacial sediments that formed in front of the retreating Laurentide ice sheet roughly ~16,000 to 13,000 years ago. The valley has been occupied by different cultures shortly after it was ice free. The frequency of sites in the valley decreases from higher elevations to lower elevations. The majority of the sites are from the Woodland and Historic periods and they occupy all geomorphic surfaces. Most sites that are associated with resource gathering and camps are found in the uplands, while more permanent settlements are located within the valley.
