The Evelyn Site is a twelve-acre archaeological site near Newark in Big Grove Township, Illinois, preserving evidence of a camp or village beside a dried-up lake from the early to middle Archaic period, around 1650 B.C. Uncovered during Commonwealth Edison high-power line construction in the mid-1970s, it was excavated by Northwestern University archaeologists. The site, also known as Illinois Archaeological Survey No. Ke-52, takes its name from the Evelyn family, whose nineteenth-century farm contained the remains. Its importance for understanding Archaic period life led to its listing on the National Register of Historic Places on December 19, 1978.
