. The "Old Reliable" Quincy Mine is considered a historical landmark of the Copper Country, a nickname for copper producing Keweenaw Peninsula, and many of the original buildings are still standing and maintained by Quincy Hoist Association. The Quincy Mine bisects the Pewabic Lode famed for its colorful datolites. Over time, the datolites had been found in the piles especially when they were bulldozed or hauled away for rock crushing. White, green, yellow, pink, red, peach, salmon, and orange are the examples found there and some come with copper specks. It's safe for me to say that the miners hit several different seams of datolites, resulting in few different varieties.
