Rolling Terrain of the Area
As the volume of glacial melt water was impounded with other watersheds, it formed glacial Lake Chicago, with water overriding the land to a 55 foot stage above the now lake level. Most of the city of Kenosha was inundated to 30th Avenue. This high stage or beach is known as the Glenwood Stage and can be seen one-half mile east of the park, east along UW Parkside’s Tallent Hall, south along 30th Avenue. It is visible just west of the Kenosha Technical Institute.
Glacial Lake Chicago soon found outlets at the now Chicago River joining the Illinois and Mississippi river then south to the Gulf of Mexico. Another outlet moved eastward through Lake Huron, Erie, and Ontario and the St. Lawrence River to the Atlantic Ocean. Glacial Lake Chicago later became Lake Michigan. The lake then established the now mean level, predicated at 580 feet above sea level.
