Hull-Rust Mahoning Mine Pit Overlook
At the beginning of this millennium nearly 2 billion tons of iron ore and waste were removed from this man made excavation. This volume is equivalent to digging a tunnel 24 feet in diameter completely through the earth. Average iron content of the ore shipped was over 60% iron with little, if any, processing of the ore required.
The largest year of production was 1942, during World War II, when more than 27 millions tons of ore were shipped during the normal nine month summer season. This required one train car of ore leaving the mine every 20 seconds for it's 90-mile journey to ore docks at the head of Lake Superior. In the 1940's more than 70 miles of rail line were used within the mine.
In 1976 Hibbing Taconite Company (Cliffs Inc.) began 'taconite' mining near the continental divide just north of the Hull-Rust Mahoning. Mining
Rain water and ground seepage at one point caused the water level in the mine to reach a maximum of over 325 feet. Subsequent pumping has brought this water level down to allow for present mining of the deeper taconite ores, as you can see below you.
