Ohio is much more careful than most other states to preserve the burial mounds of the native Americal Peoples. I am unaware of any mounds preserved and recognized as such in Michigan. Yet common sense tells us that hey must exist although the likelihood is strong that many have been desecrated.
Monroe is built on a swampy flat lake bottom. A raised place of this type is very likely to be an Indian burial mound. Bones of unknown origin are found in this site. Following the River Raisin Massacre It was used as a temporary burial place for the unidentified remains of Kentucky militiamen who died in the massacre. These remains were subsequently removed to Kentucky.
Other persons buried here include victims of a Colera epidemic that occurred in approximately 1836 before this monument was erected and dedicated in 1904. Gravestones were erected for some of the cholera victims but appear to have been moved out of the way to make a place for this large granite monument. The cholera victim’s stones are laid flat at the rear of the mound and any mound made level for a park.
It is also possible that at the time of the dedication of the monument many wagon loads of dirt were hauled that composed the soil overburden for one or more local quarries. Several local limestone quarries were being developed at that time that easily could have supplied the soil. Thus it may not be an Indian mound but there is strong conjectural evidence that is.
