What Rare Rocks Can You Find in Wisconsin
The most popular rare rocks that you can find in Wisconsin are Lake Superior:
- agates,
- jaspers,
- yooperlites,
- obsidians,

Lake Superior agates tend to receive the spotlight in this state, but yooperlites and petosky stones are also popular finds that are worth the effort to find.
