More on Midwestern Glacial Gold (Part 1)



(The Midwestern states.)

Ask Any Midwestern Miner

In previous posts in"Bedrock Dreams" I've written about glacial gold locations in Ohio, Indiana, Illinois, as well as the gold potential of Minnesota. In this post I'll be taking a broader view of glacial gold in the Midwestern U.S. as a whole.

(Note: My write ups on where to find gold in Illinois and Indiana are no longer in the "Bedrock Dreams" archives but are included in my mining ebooks, "Where to Find Placer Gold (List A)" and "Where to Find Placer Gold (List B"). J.R.)




I know the idea of placer, lode, or glacial gold in the Midwest is alien to most prospectors and miners in the mountain West and the Southwest, but just ask any Midwestern miner worth his or her salt...they'll tell you. Sure, Midwestern glacial gold is mostly smaller in size and a perhaps bit lacking in quantity in many instances, but it's there none the less.

Where is Midwestern Gold?

How did glacial gold turn up in the Midwest? Yep, you guessed right...via glaciers and glacial activity starting around one million years ago.

Pushing down from what is now Canada, these glacial advances and retreats ended about 10,000 years ago (give or take a few thousand years). The extreme limits of the most extensive gold-bearing glacial surges included the following states and areas:

East central North Dakota
East central and eastern South Dakota
Extreme eastern Nebraska
All of Minnesota
Nearly all of Iowa except the extreme southwestern part
North central Wisconsin
Extreme northern and the southeastern third of Michigan
Eastern half of Indiana
Extreme western and north central Ohio


Canadian "Goldfields" as the Source

You'll notice that Illinois and Missouri are not included here, despite the fact that glacial advances covered the entire state of Illinois and the northern third of Missouri as well. However, glacial gold deposition was not as extensive or "rich" in these two states as it was in those listed in bold type above.

Most of this glacial gold traveled south into the U.S. from gold lodes or placer goldfields in Canada, many of which were mined and developed in the past (or still are, for that matter). These Canadian glacial gold sources include the following mining regions:

Red Lake
Kenora
Geraldton
Ropes
Porcupine
Timmins
Noranda
Malartic
Sudbury

I'll have more on Midwestern glacial gold in subsequent posts. Until then, hang tough and the best of luck to you.
