GEOLOGIC HISTORY
The geologic history of the Menomonee River is very interesting. Over 600 million years ago, a tropical sea advanced and receded over Wisconsin several times. Plants and animals living in the sea deposited layers of calcium carbonate or coral reefs in scattered areas, including Menomonee Falls. The underlying bedrock throughout Menomonee Falls is evidence of this coral reef. During Wisconsin's last glacial advance over 15,00 years ago, a portion of the advancing ice sheet known as the Lake Michigan Lobe  rested on the top of Menomonee Fals. When the glacial period ended some 10,000 years ago, the ice sheet left behind deposits of glacial till which covered much of the bedrock except for an area along the Menonomee River between the Lepper Dam and the Lime Kilns. Limestone outcroppings and rocky cliff walls are bedrock formations that are still visible. The high quality of this bedrock was the main reason why Garwin Mace, the first Village President, established a limestone quarry and a lime processing operation in this area over 100 years ago.
The marker is located on the west bank of the Menomonee River, adjacent to the Lime Kiln Park parking lot accessible from northbound Mills Street between Appleton Avenue / Wisconsin Highway 175 (to the south) and Main Street / Wisconsin Highway 74 (to the north), Menomonee Falls, Wisconsin 53051.
