• Mid Holocene riparian forest
• Archaeological site of mid-Woodland settlement
In June 2011, local archaeologist Dave Wasion provided notes and assistance in locating his original excavation along Barnes Creek. The Barnes Creek Site is situated on high banks of the Barnes Creek, a 6 km stream flowing to Lake Michigan near Carol Beach in Kenosha County. The Barnes Creek site includes a prehistoric archaeological site listed on the National Register of Historic Places. The younger sediment levels contain a pre-Columbian American Indian settlement dating to the mid-Woodland periods of 200 to 1400 AD. Four specimens of sycamore excavated from the northeast streambank had 30-70 rings that are dated ca. 5800-6100 Cal Yrs BP. Radiocarbon dating of wood from this Creek by Curt Larsen in the 1990s gave a slighter younger age of the wood deposition – ca. 5360 and 5550 Cal Yrs BP, but they were likely farther downstream from the Wasion site.
