Jackson Mineとは 意味・読み方・使い方

The Jackson Mine is an open pit iron mine located northwest of intersection of Business Route M-28 and Cornish Town Road in Negaunee, Michigan. It was designated a Michigan State Historic Site in 1956 and listed on the National Register of Historic Places in 1971. The Jackson Mine was the first iron mine in the Lake Superior region, and as the Lake Superior Mining Institute put it, the mine "is attractive in the iron ore region of Michigan and the entire Lake Superior region, because of the fact it was here that the first discovery of iron ore was made, here the first mining was done, and from its ore the first iron was manufactured." Multiple other mines soon followed the Jackson's lead, establishing the foundation of the economy of the entire region.
