Dwarves' Earth Treasures Online Museum: Clark Datolites
Clark Mine, Copper Harbor, Keweenaw
CO., Michigan
.
The Clark Mine is one of most well-known and most visited
mine for the datolites that it was mentioned even in many old books on
collecting in Michigan and even today, it is still being visited by many
people. With an exception of illegal attempt at bulldozing, it's one of
very few mines that I know of that had not been bulldozed. Many datolites
from Clark Mine seem to consist of many datolite nodules squeezed together
while regular datolites are usually dull white. I'm starting to see some
orange datolites from Clark Mine.
