Geodes are like hidden treasures buried in plain sight. They look like any old rock on the outside, but inside, they’re a whole different story. Think of them like a piñata, but they’re filled with crystals instead of candy.

Geodes are hollow rocks that contain a cavity lined with crystals or other minerals. They come in all shapes and sizes and are formed through a process that can take thousands of years. Some are big enough to fit in your hand, while others can be as large as a basketball.

We’ve also developed a guide for geode identification if you want a more extensive explanation.

Geodes are found all over the world, from the deserts of Arizona to the beaches of Brazil. The exceptional geology of Wisconsin makes it easy for geodes to form. People love to collect them because they’re so unique and beautiful. They’re like nature’s little surprises, just waiting to be discovered. So, keep your eyes peeled for these little wonders next time you’re exploring. You never know what kind of treasures you might find!

Check for our best suggestions for geode spots around the state to get things started. While there are many wonderful places to mine for gems in Wisconsin, only a select few are ideal for looking for geodes. Some places have always given us great search possibilities while being uncommon.

Always Confirm Access and Collection Rules!

Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations directly with the location. We haven’t personally verified every location and the access requirements and collection rules often change without notice.

Many of the locations we mention will not allow collecting but are still great places for those who love to find beautiful rocks and minerals in the wild without keeping them. We also can’t guarantee you will find anything in these locations since they are constantly changing. 

Always get updated information directly from the source ahead of time to ensure responsible rockhounding. If you want even more current options it’s always a good idea to contact local rock and mineral clubs and groups

Milwaukee County

Milwaukee County is a place that’s full of character and charm. The county is located in the state’s southeastern part and is known for its diverse geology, terrain, and geography. It’s like a patchwork quilt of different landscapes that come together to create a beautiful picture. The terrain in Milwaukee County is varied, with rolling hills, flat farmland, and forested areas.

The county is located on the western shore of Lake Michigan, meaning it has a lot of flat land that’s great for farming. But as you move away from the lake, the terrain becomes more hilly and forested. The county is also home to several rivers and streams that add to the beauty of the landscape.

Regarding geology, Milwaukee County is located on a bedrock of sedimentary rock over 400 million years old. Glacial deposits cover the bedrock from the last ice age, which makes for some interesting geological features like eskers, kettles, and moraines. These features were created by the movement of glaciers and are a testament to the power of nature.

Be sure you’ve researched the most recent Wisconsin State collecting laws before bringing your unearthed treasures home.
