.	Dwarves' Earth Treasures Online Museum: Mesnard Datolites Mesnard Mine, Hancock, Houghton Co., Michigan	.

 .        The Mesnard mine is the eastern extension of "Old Reliable" Quincy Mine along the Pewabic Lobe famed for its colorful datolites. There was a story of young men sneaking down the shaft of the Mesnard Mine and bringing back up with a bucket of yellowish to reddish datolites (illegal collecting!). The dark skinned datolites from Mesnard mine come in quite a wide range of colors such as white, pink, peach, red, orange and yellow and some are coarse grained. The collection of datolite is still severely limited since the piles are owned by Quincy Hoist Association and collecting is usually not allowed. I think the piles were opened to collecting few times during Keweenaw Week.
