Dwarves' Earth Treasures Online Museum: Isle Royale Datolites
From the old mines of Isle Royale,
Michigan
.
.
It appears that few people did visit Isle Royale island in the past and
collected some datolites from the mine pits before the federal government
placed a ban on any rock collecting on the island. The old collection of
datolites from the pits of Isle Royale showed up and I was able to obtain
few datolites from it. Most datolites seem to be white with pink centers
and few coming with orange and yellow colors.
