.	Dwarves' Earth Treasures Online Museum: Franklin Datolites Franklin Mines,  Hancock, Houghton Co., Michigan	.

 .        "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 preserved. The Quincy and Mesnard Mines are very well known for producing many highly prized colorful datolites and some coming in baseball-sizes. Since Quincy, Mesnard and Franklin mines are connected to each other that it's not easy to tell the datolites from the mines apart. The mine dumps of Franklin already have been taken away for road-making so no more datolites coming from Franklin.

Faint yellow color with red dots.	Pinkish with dark dots all over.
