Types of Geodes Found in Wisconsin


Geodes can be of different types and colors, but in Wisconsin, you will mostly find chalcedony geodes. 

Chalcedony geodes are among the fascinating geological formations found in Utah. They are typically developed in volcanic rocks, such as basalt or andesite.

These geodes exhibit a spectrum of colors, including various shades of white, gray, blue, and purple.

Where to Find Geodes in Wisconsin

1. Milwaukee County

Milwaukee County

Despite being a predominantly urban area, Milwaukee County offers surprising opportunities for geode hunting. The glacial history of Wisconsin has left a mark on the landscape, and glacial deposits in Milwaukee County can harbor geodes.

Head to the riverbanks, especially along the Milwaukee River, and explore areas with exposed sedimentary rocks for geodes. Look for eroded banks and gravel bars, where geodes may be uncovered by the natural forces of water.

There are multiple rock and minerals clubs in the area that organize field trips in the region, offering a great opportunity to get to know the location for geode hunting.

2. Black River and Tributaries

Black River and Tributaries

Moving westward, the Black River and its tributaries in western Wisconsin boast a geological richness that attracts rockhounds from far and wide. The river cuts through layers of sedimentary rocks, creating prime conditions for geode formation.

While the exact locations may vary, focusing on riverbanks, especially near exposed cliffs and outcrops, can yield positive results. Local parks in the area, such as Black River State Forest, offer an excellent geode hunting opportunity.

Black River is also famous for its Agate and Jasper.

3. Pepin County

Pepin County

Pepin County is another promising destination for geode hunting in Wisconsin. The mix of sedimentary rocks and glacial deposits provides an ideal environment for geodes to form.

Head to the bluffs and hillsides that surround Lake Pepin, where geological processes over millennia have created pockets of geodes waiting to be discovered. Also, check out the quarry on Big Hill Road to look for geodes.

Be sure to check with local authorities or geological surveys for any regulations or guidelines regarding rock collecting in specific areas to ensure responsible and legal exploration.

4. Plum Creek

Plum Creek

Located in the southwestern part of the state, Plum Creek is a lesser-known but equally fascinating location for geode hunting in Wisconsin.

Geodes in Plum Creek may be found in gravel bars, exposed rock formations, or eroded hillsides. The region’s relatively quiet and secluded nature adds to the allure of the hunt.

The place is also famous for its diamond and gold reserves.

5. Mississippi River Beds

Mississippi River

The expansive Mississippi River beds that define Wisconsin’s western border are rich grounds for geode exploration. The river, with its constantly shifting currents, exposes various layers of rocks and sediments, creating prime conditions for geode formation.

Areas near the riverbanks, sandbars, and exposed bluffs are potential hotspots for geode hunting. The sheer size of the Mississippi River provides ample opportunities for enthusiasts to explore different sections and discover hidden geodes.

6. Outagamie County

Outgamie County

Situated in the eastern part of Wisconsin, Outagamie County offers a different geological setting for geode hunters. While the county may not be as well-known for its geode deposits as some other regions, there are still promising locations for those willing to explore.

Check out riverbanks and exposed rock formations in Outagamie County, especially along the Fox River. Due to the glacial history of the region, you may find geodes in areas where glacial activity has deposited rocks and sediments.

You will find plenty of gems in the county such as Ruby and Sapphire. 

Necessary Tools for Mining Geodes in Wisconsin

Before hunting for geodes in Wisconsin,  make sure you have the required set of professional tools and equipment. Here are a few things to keep in mind.

  1. Shovels and Trowels: For digging into softer soil, you need a sturdy shovel or a trowel. It also helps clear away the debris on the surface.
  2. Buckets: As you uncover gems, you need buckets to place them. Make sure you have durable buckets for the job to make sure your gems remain undamaged.
  3. Picks and hammers: To split rocks, and extract gems, you need a pick with one pointed end, and the other flat that serves as a hammer.
  4. Magnifying glass: For a closer inspection of your specimen, you need a magnifying glass to reveal details that are not visible to the naked eye.
  5. Zip-lock bags: As you collect gems, you need clear plastic containers or bags to store them. It also allows you to see the gems without having to open the bag.
  6. First aid kit: Mining is a risky venture, so make sure to keep a first aid kit with you at all times so you can address accidents or injuries promptly.


Wisconsin, with its diverse geological history and varied landscapes, offers a wealth of opportunities for geode enthusiasts. Before embarking on a geode hunting expedition, it’s essential to research local regulations, obtain any necessary permits, and respect private property rights.

If you are planning to look for geodes in Wisconsin, you can even join local rock and minerals clubs to enhance your overall experience and get to know the terrain better.

Whether you are a seasoned collector or a novice hunter, Wisconsin offers plenty of spots for geode hunting as mentioned in this guide. Good luck unlocking the geological secrets hidden beneath the surface of the Badger State.
