What to Look For
When rockhunting in the Upper Peninsula, there are several types of rocks and minerals you might find:
- Lake Superior Agates: These are the most sought-after stones, characterized by their rich red and orange bands.
- Datolite: Often found in the Keweenaw Peninsula, these nodules can be white, yellow, or even pink.
- Native Copper: The UP’s mining heritage means there’s still copper to be found, especially in old mine dumps.
- Greenstone (Chlorastrolite): Michigan’s state gem, often found in Isle Royale and Keweenaw Peninsula, is a beautiful green mineral with a turtle-back pattern.
- Yooperlites: Yooperlites are syenite rocks that contain sodalite, a mineral known for its fluorescent properties. Under normal light, Yooperlites appear as ordinary grayish or tan stones. However, when exposed to ultraviolet (UV) light, they reveal an astonishing glow, typically in shades of bright orange and yellow. This luminescence is due to thepresence of sodalite, which fluoresces under UV light.
