The stone entryway at Picnic Point was constructed under the direction of Edward Young by one of his employees.
Stones for the wall were gathered from around southern Wisconsin, probably in the late 1920s. The diversity of rock specimens in the wall—thanks to the glaciers that transported them to the region—makes it an ideal teaching aid for geology students on campus.
A Key to the Glacial Erratics in the stone wall can be found on the Friends of the Lakeshore Nature Preserve website. You can also download a pdf of the Key.
