The Esch Mounds were a pair of conical burial mounds located along the Huron River in Erie County, Ohio. Emerson Greenman conducted early excavations at the Esch mounds in 1930. The artifacts he unearthed, including platform pipes and bladelets made from Flint Ridge flint, indicate both mounds belong to the Hopewell culture. A radiocarbon date obtained later shows that the Esch mounds were built around A.D. 590, which is very late in time for a classic Hopewell site.
The most remarkable artifact found in the Esch Mounds is an effigy pipe carved in the form of an alligator or a mythological creature, such as the Underwater Panther.
