The Hull Rust Mahoning Mine sits at the north edge of Hibbing, and it is roughly three miles long, two miles wide and more than five hundred feet deep. People call it the Grand Canyon of the North, which sounds like local exaggeration until you stand at the overlook and try to find the far side.
This is where the Mesabi Range gave up most of what it had. Iron ore came out of this pit for well over a century, and at its peak it was producing a quarter of all the iron mined in the United States. During both world wars the ore that went into ships, tanks and rifles came out of holes like this one, hauled by rail down to Duluth and Two Harbors and loaded onto boats.
The scale is hard to process from photographs. Haul trucks working the floor look like toys. Their tires stand taller than a person, and there is one propped up near the visitor area so you can put your hand on it and recalibrate. Benches step down the walls in terraces, each one a road wide enough for equipment, and the exposed rock runs through rust orange, deep red and pale gray depending on the seam and the weather.
The strangest part of the story is what the mine did to the town. Hibbing was originally built somewhere else. By 1919 the ore under the original townsite was worth more than the townsite, so the mining company moved Hibbing. Not the people. The buildings. Homes and businesses were jacked up, put on rollers and hauled two miles south. Some structures were too large and were cut in half. A few were left behind and swallowed. North Hibbing is still there as a scattering of foundations, curbs and empty streets where a neighborhood used to be.
That relocation is also why Hibbing High School exists in the form it does. The company paid for it. The building has a marble-columned auditorium modeled on a Broadway theater, with cut glass chandeliers, and it sits in a town of sixteen thousand people on the Iron Range.
There is a free overlook with a small visitor center open in the warm months. Volunteers work the desk, many of them retired miners or the children of miners, and they will tell you which company ran which section and what year their father worked it.
Mining continues nearby. The pit is not a museum piece. It is an open wound in the earth that built a state, and it is still being worked.
