This tiny park is at the corner of Midwood and Ridgewood Avenues, and contains an Indian burial mound believed to have been built around 1,500 years ago by the Hopewell Indians. This mound was unintentionally cut into during street construction in the 1940s and skeletons were uncovered. These skeletons were noted at the time by the State Historical Society to be one of the most important archaeological discoveries ever made in southern Wisconsin. A State of Wisconsin historical marker was placed at this site in 1998, inscribed with the following:
“The Outlet Mound"
“The largest of 19 conical, oval and linear mounds once located in this vicinity, the Outlet Mound was built by Woodland Indians about 2,000 years ago. Constructed as a burial place, the mound was saved from destruction by the Wisconsin Archeological Society and local citizens in 1944 and donated to the City of Monona.”
