The Cascades is located along the Current River in Thunder Bay’s conservation area.

The Cascades is known for its rich geological history.

The rocks are some of the oldest found in the world, dating back farther than 1.2 billion years.

It is chock full of different rocks, stones, and minerals.

Amethyst can be found, along with agate, hematite, local silver, copper, and, if you’re lucky, even diamonds.

The sedimentary rock in the region is often rich in iron, creating beautiful red banding in the stones.

There are shallow areas in the river that have unique growths of chert poking out of the water, which, when cracked open, can contain agate or red jasper.

While this is not an official mine or rockhounding location, it is a wonderful area to explore at your leisure.

The Blue Point Amethyst Mine

Since amethyst is so abundant in southern Ontario, there are some very famous mines that you can visit to find your own.

For just $20 (Canadian dollars), you can collect up to two gallons of amethyst crystals.

This is one of the most popular destinations for rockhounders visiting Thunder Bay.

They offer guided tours or the freedom to mine by yourself.

It is located a little over an hour outside of the main city of Thunder Bay, about 30 miles northeast.

You drive along a well-maintained dirt road (don’t worry, there are lots of signs), and arrive at the mine, where they equip you with a gallon-sized bucket, adequate wrapping for damage-free crystal travel, and what is almost a free-for-all inside the mine.
