RE: Daily Dose of Sultnpapper 04/07/18> Tell me again… where does oil come from?
I'm no geologist but in my hometown there are deep dug quarries nearby. As a teenager I visited some and found fossils of sea creatures inside the quarry rocks. I don't get it because Chicago is so far from the sea. I think the earth was in great catastrophe at one point. A flood might have caused these rocks to form.
Well with Chicago right on the shores of lake Michigan, that might have been ocean at some point in the past.I don't think there is any way to know for sure though.
