Thomsonites are often found
in the waters and on the shores of Isle Royale and in
some areas of the Michigan copper ranges of Lake
Superior. Many of the old tailings of the Copper mining
era have Thomsonites in them. Look for white chalky,
small round or almond shape nodules in the poor rock. The
problem of course is getting them out of the rock without
damaging them. Sometimes they will have weathered out of
the rock and can be found lying on the ground. (These
usually will be soft and sometimes not much good, but
occassionaly a good one will be found.) Thomsonite Hill at Pole 30 on the road from Deleware to Eagle Harbor is famous for its Thomsonite. I have heard that the property has been sold, so check first before digging. The road cut at the crossing of Owl Creek is another place to dig Thomsonite. You will see the small white nodules that have weathered out of the rock. I have had best luck on the east side of Owl Creek. Also, check the road that goes into Copper Falls at the Y and to the left near the top of the hill. This is the same ridge as the Thomsonite Hill area. Thomsonite specimen as a rule, are quite small. A little finger nail-sized stone with good radiating pattern can be considered a nice specimen. Thomsonite larger than this possessing a good radiating pattern are extremely hard to find. Be sure to visit our Auction site for Thomsonites.
