Points North: A discovery in the Straits
A group of tribal citizens and activists have uncovered a potential cultural site at the bottom of the Straits of Mackinac from close to 10,000 years ago — the end of the last Ice Age. Researchers say it could be a major archeological find.
But the site is in a precarious place. It straddles Line 5, the oil and gas pipeline, where oil company Enbridge wants to build an underwater tunnel.
