Madison Mine

“The Madison Mine is one of the dozens of fissure mines scattered across the Keweenaw’s northern reaches that produced very little copper and even less interest. Organized in 1853 the mine attempted to pillage a pair of small fissures veins a mile east of Central without much success. For thirty years various attempts were made at the site but through all only limited amounts of copper were ever secured. By the 1880′s the old mine was gobbled up by its more successful neighbor to the west but was never worked again. Besides the nearby gap which also bears its name, very little of the old mine has survived save a few scattered rock piles and the subject of our post today – its powder house.”
