Keweenaw week is a week of field trips to the
various waste rock dumps of mines on the Keweenaw peninsula (two field trips
each morning and afternoon for six days) and underground collecting in the
Caledonia mine; a reception at the Seaman Museum; lectures on various topics of the mines, their minerals and
history; trips to view the historical remains in the area; a rock swap (local
collectors selling specimens) and a weekend rock show; and a keynote address and
auction. The club is able to secure permission to enter rock piles which are
normally off limits to collecting.
The Wednesday evening rock swap/sale at the Quincy is one of three opportunities
to buy specimens.

as copper, datolite, mining artifacts (such as copper chips from the chiseling
of mass copper) and micro mineral specimens (This is at the Rockland mine

shafts that followed the dip of the ore beds.
