Mesnard mine is the eastern extension of the Quincy Mine along the
Pewabic Lode 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 the 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 tours few
times during Keeweenaw Week. Some miner named Bud Townsend was
said to picked up the best datolites during his work at Quincy,
Mesnard and Franklin mines and I was able to obtain a few.
