View it big and on black for the full effect! Stars rotating over the ruins of the Isle Royal #6 rockhouse. A massive structure once rose above these huge cement foundations, processing rock from the nearby shaft (just to the left, where a snowmobile trail now runs!). Trains would pull through the slot between these walls to cart away copper-bearing rock to the mill.
