Photo taken by Andrew Wood in June 2011
Sorry to say, this is incorrect. Coe Mound is several miles north of this photo, in a restricted and undisclosed location. The photo here is a pile of dirt at Clinton-Como Park, used as a sledding hill by local kids and originally formed by leftover dirt from a sewer project.
Great find, Andrew. I think this site should be added to the Effigy Mounds category as it seems to meet the qualifications for inclusion.
