A copper specimen from one of the most difficult to obtain of the various Michigan copper localities. Unlike almost all the other specimens that came from old mines or the waste piles that they left behind, this location was discovered in the early 90's by local collectors scouting land that had been cleared for logging roads.  This place is pretty much at the end of the Keweenaw peninsula, just a couple miles from where it juts out into Lake Superior.  To give a sense of rarity, there are only 2 other examples from here pictured on MinDat. This is a reasonably large arborescent cluster of crystals that have been etched out of a tough silicate matrix.
