Archaeologists in Michigan have excavated a Native American camp near Dumaw Creek  Radiocarbon dating of animal bones found at the site indicates that the camp dates from some time between 1605 and 1755
However, the camp probably dates to no later than 1630, since no European trade goods were found at the site, and European traders were active in the region from the 1620' s onward
The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.
