Summary:

The Calumet Waterworks is a local favorite - but also a favorite for travelers. This is always one of the more popular rockhounding spots when I visit the Keweenaw Peninsula. With that said, you can still find some fantastic rocks here - especially if you get in the water, including agates. For best luck, come in the early Spring right after the ice melts if you’re on the hunt for Lake Superior Agates.

Note: There is no video for this location. My last visit was prior to starting the channel/website.

If I could only bring 3 tools…

Chest Waders

Chest waders were the single best investment I made for exploring the shores of Lake Superior.

Agate Scoop

An agate scoop is helpful for both keeping dry and picking up rocks faster. You don’t need a fancy one. Mine is a golf club welded to a kitchen scoop.

Classifier

A classifier is helpful if you’re a fan of small agates and stones. One with a larger, 1-inch mesh would be what I’d pick.
