Clark Mine, Copper Harbor,
Under Forestry Management. OK to Collect but at one's own
The Clark Mine is one of most well known and most
mine for the datolites that it was mentioned even in many old books
collecting in Michigan. Even today, it is still being visited by
people. It is funny how the Clark mine is better known for its
instead of copper, and like Star, Montreal and other nearby mines,
Mine is one of those early mines that opened during 1840s to 1860s
period. They did not produce sufficient supply of copper that they
were abandoned quickly.
With an exception of illegal attempt at
(he was caught), it's one of very few mines that I know of that had
been bulldozed or hauled away for rock crushing. Many datolites from
Mine are white with an appearance of many datolite nodules being
squeezed together. Few orange datolites had been found in some spots
Mine (not counting the Clark Swamp Adit).
