Iron Mines in Michigan - NASA

The Empire Mine, which produces about 5.5 million tons of magnetite each year, is on the east side of the complex; Tilden Mine, which produces about 8 million tons of hematite and magnetite each year, is just to the west. Exposed rock and dirt in the mines appear gray compared to the surrounding forest. Large pits, piles of rock, processing facilities, roads, and railroad tracks are visible within both mines.

Actually, the Spurr Mine is quite easy to find. At the Craig Lake State Park turn just west of Michigamme, look for a turn to the right. The Spurr Mine just on the other side of a pond, about 50 - 100 yards from the road. The replacement garnets are nickel-dime sized and are generally easy to find. Another common mineral here is grunerite, an uncommon asbestos type mineral.

Grypania spiralis in the Empire Mine Core Dump

The Empire Mine, which has been working the Negaunee iron formation for about 50 years, is the location of the oldest known eukaryotic body fossil, Grypania spiralis. It's funny, but I grew up only 5 miles from the site and never about it until I found it in an Evolutionary Bio text in 2005. I went on several mine tours in the mid 1990's as a reward for being a good student but all we ever learned about was

STATE OF MICHIGAN MICHIGAN'S MINERAL INDUSTRIES, 1962

Michigan's iron mines were appraised for 1963 tax purposes at $55.3 million, nearly $13 million less than last year. This figure reflects a five-year downward trend in demand for iron ores and continuing decline in underground reserves. The Cleveland-Cliffs Iron Company suspended operations at its Cliffs Shaft and Mather mines during
