Millions of years ago, Wisconsin was covered by a vast, shallow inland sea, teeming with marine life. Over time, the shells of animals such as gastropods and corals became fossilized in limestone deposits. Twelve thousand years ago during the last ice age, a glacier advancing toward Lake Michigan made striations, or scratches, in the exposed limestone.

Look for fossils and striation marks on the bare limestone at Quarry lake.
