Me too Donna, I never knew about this quarry. Or that quarry locations were selected according to the "impurities". Based on today's photos, I never really got the impression of it's depth, was it maybe an underground mine (since the mention of the caves)? Then I found this photo via Mary's link. It shows some better perspective.
I measured the size at 60 acres. For comparison, the largest limestone quarry in Michigan is Rogers City, at over 3,000 acres.
I still have a goal to reach the old Slate quarry northeast of L'Anse. My pickup almost made it down the 2 track and water kept me from walking in the rest of the way. I DID get a nice specimen though.
