This is a great summary of the geology of Michigan. I was able to take a field trip to the U.P. with a geology class and see the old, volcanic rocks that are present up there as well as take a tour of an operating copper mine. I thought it was very interesting that organisms such as gastropods and stromatolites were present during the Cambrian time.

The gypsum that you speak of was mined until about the year 2000 in the Grand Rapids area. I worked with a guy who was a blaster first in the mines by Butterworth (where there remain concerns about sinkholes due to the shallow nature of the mine) and then at the mine near East Paris street out by the airport until he was layed off when the mine closed. I believe that one of the mines in the vicinity of the CSX rail yards is still used for document storage. So the Jurassic beds were used economically and may include potentially mineable potash deposits around Mecosta county. Still a good video so I will be leaving a thumbs up.

Interesting video, im no Randy Marsh so im not so smart with geology. But I remember knowing that because of the ice sheets, it exposed a lot of copper for native Americans to use and trade, essentially creating one of the earliest metal working civilizations. Also its native copper, i dont know how special that is in geology, but i love the pretty copper ores and malachites we get from the UP

It’s refreshing to see climate change being shown and the consequences explained in geological records after all climate change is currently being blamed on human activity. Folks, climate change is continuous wether humans are here or not. The planet is alive and continues to evolve.

Yes, the earth’s climate has always changed. What is different now is the RATE OF CHANGE. Burning of fossil fuels (mostly) has altered the atmosphere unusually rapidly since the dawn of the Industrial Revolution. One of the downsides is that most species are unable to adapt to such rapid change.
