They are digging up an old meteorite

The object responsible for creating Sudbury Basin crashed into Earth about 1.8 billion years ago. That makes this crater in Canada fifty times older than Popigai—one of the world’s most well-preserved craters—which was created a mere 36 million years ago. Much of Sudbury’s original crater, thought to have measured at least 200 kilometers (120 miles) across, has been deformed and eroded. Despite this, the crater has had a lasting impact on the region.
