I love the ancient geology. In Michigan’s upper peninsula are the Porcupine mountains that were once much taller. The ancient rift valley that makes up the deepest part of Lake Superior. I live atop the Michigan basin that is surrounded by the Niagara escarpment which is visible from near Green Bay, along the southern upper peninsula shore down separating Lake Huron from Georgian bay before going underground till it shows itself where the Niagara fall fall over it.

I love the ancient geology.

Yes, it is truly fascinating once you start reading up and learning about it. You can also watch great TV series on the subject at YouTube, such as How The Earth Was Made...

You do indeed have some ancient rocks in your part of the country. Below is a map of the underlying "basement" bedrock of North America. aka, the North American Craton. Estimated ages are displayed on the various segments. The continent grew piece by piece over several billion years. The Earth itself is ~4.6 billion. "b.y." = billion years
