From the page: "A forest fire has led to a chance discovery of debris from the impact of a meteorite 1.85 billion years ago, more than 450 miles away at Sudbury, Ontario...
"Previously, material thrown out by the impact had been found as far from Sudbury as Hibbing, about 125 miles farther to the southwest from Grand Marais. However, the tiny fragments at Hibbing were found in core samples from 800 to 1,000 feet below the surface, while the rock layer containing larger chunks at the Gunflint site lies exposed."
