The Zimmerman Kame (also called the "Zimmerman Site"; designated 33HR2[2]: 1 ) is a glacial kame and archaeological site in McDonald Township, Hardin County, Ohio, United States, near the community of Roundhead. A circular hill approximately 20 feet (6.1 m) in height, it was a commercial gravel pit for a time before being abandoned in the 1970s after artifacts of the ancient Glacial Kame culture of Native Americans were found at the site.[2]: 2 Today, the kame is tree-covered and surrounded by farm fields; there are no obvious signs of its significance.
The Zimmerman Kame is one of many archaeological sites in Hardin County. A survey conducted in the early twentieth century revealed at least five different archaeological sites in McDonald Township and the adjacent Roundhead Township and a total of forty-four sites across the county. Many burial sites were located on top of hills such as the Zimmerman Kame.[3] Among the most significant artifacts found at the Zimmerman Site were small objects of pottery; previous to the Zimmerman discovery, the Glacial Kame people were not known to have produced ceramics.[2]: 3
In 1974 the site was listed on the National Register of Historic Places because of its potential to yield more information about the Glacial Kame culture.[4] It was the first such kame to be listed on the Register.[2]: 3
