I Could've Stood Here 1 Billion Years Ago | The Story of Blackrocks

In Marquette, Michigan, there's a park with some bizarre, pillowy-looking black rocks. To understand where they came from, I found an expert, who took me on an adventure to (literally) stand on the Earth's surface as it was a billion years ago.
