NEGAUNEE — Carol Fulsher was all smiles when the subject of the Iron Ore Heritage Trail came up Monday afternoon. It wasn’t just because she and the other volunteers who were near the Jackson Mine in Negaunee were passionate about local history, but also because she was standing on the very first section of the trail to be paved. “We’re expecting it’s going to take about a week to finish the asphalt portion of this trail,” said Fulsher, who is a member of the Iron Ore Heritage Recreation Authority board of directors as a representative for the city of Marquette. “What this does is it gives us a start on this trail in a location where the iron ore industry really started. This is where the first survey team found iron ore and the Jackson Mine was the first mine. It’s all so historic.” The 3-mile portion of the trail being paved runs from the old Brownstone buildings area in Ishpeming east to the Negaunee Senior Center.
