After the addition of the railroad in 1888, the mines began shipping the iron ore to the docks of Lake Superior in Two Harbors, MN. Originally, the mining was an open pit operation since there was an abundance of iron ore on the surface. Later, deep shafts were made to start mining underground. In 1967, the Pioneer mine closed.
