Hunting for Agates in Minnesota: A Rockhound’s Guide

What Even Are Agates?

Agates aren’t just any old rock. They are a type of quartz that showcases beautiful banding patterns, often seen in shades of red, orange, and yellow. These colors are made from iron deposits oxidizing over the course of several millions years. In a way, they are Mother Nature’s way of painting rocks!

Like snowflakes, no two agates are alike. Each one comes with its own story, with unique designs specific to that rock. Agates are also incredibly durable, with a hardness score of 6.5-7 on the Mohs scale. Because of this, agates are great pieces for jewelry, displays, or even as a lucky pocket stone. People drawn to their beauty, as well as those seeking the thrill of the find, will be drawn to the Minnesota waters in search of this natural phenomena.

Where to Find Agates in Minnesota

Now for the fun part—where are the best places to go rockhounding in Minnesota? Where can you find these beautiful creations? Technically, you can stumble upon an agate nearly anywhere, but here are some prime rockhounding grounds that’ll increase your odds:

1. Lake Superior’s North Shore

Easily one of the best places to find agates in Minnesota, come and try to find some Lake Superior Agate. These rocks were carried by glaciers thousands of years ago, and are Minnesota’s state gem. Some of the best spots include:

Brighton Beach: Located in Duluth, this is a classic stop for rock pickers. With close proximity to Lake Superior, this stone-covered beach is teeming with agates.
Gooseberry Falls State Park: Situated in Two Harbors, explore the spectacular waterfalls and scenic overlooks. Run along Gooseberry River, and explore the rocks underneath the waters.
Grand Marais Beaches: Within the city of Grand Marais, stretch your legs along the shores as you explore the various beaches for these gemstones. They even have a beach dedicated to the rocks named Agate Beach!

2. Gravel Roads and Driveways

With glaciers spreading agates across the states, it is all too common to find them in simple gravel pits and roadways. Especially after a fresh rain, take a walk along a gravel road or driveway and keep your eyes peeled. You might just spot one shining in the dirt.

3. State Parks and Public Lands

Although some state parks don’t allow rockhounding, they are still a great spot to locate an agate. Parks such as Jay Cooke State Park and Tettegouche State Park have riverbanks and hiking trails perfect for locating the gems. Just remember to leave them for everyone to enjoy.

Even if collecting is restricted in state parks, these locations still provide awesome opportunities to observe agates in the wild, and appreciate their formations. Additionally, you can improve your rock-hunting skills when you visit a place where collecting is allowed!
