Field CollectingMichigan Septarian?

7th Jan 2005 15:29 UTCRay Clay

I was at a couple of Michigan rock shows last fall and they had a bunch of Septarian Nodules collected in Michigan (Glen area?) I have searched all over the net for any leads on WHERE... to no avail. Anyone have any info on this?

Thanks!

There are about a dozen localities for calcite concretions listed in the new "Mineralogy of Michigan" by Heinrich and Robinson.

There is a picture in "Mineralogy of Michigan" of a septarian nodule from Glen. The "matrix" is a dark brown, while the calcite is more yellow.

Umm....

Thanks for all the info.

Everett, may I email you with more questions on the location that you described?

David, thank you for letting me know that I HAVE TO buy a certain book if I want to find this information, it was very helpful. I was not aware that that was the only way to get this information. How enlightening.

Ray,

We live on a bluff overlooking the big lake and have access to septaria. How many lbs. are you interested in? What might you have to trade, or ?

Where do you live?

Regards,

Bob

Hi gang,

thought I'd share my finds from this location. I had a great day hunting here at Deer Lick.

i"m in a rock club in michigan. the old timers tell me that after some storms the nodules make it up to shore of lake michigan or shallower water. i've heard like the south haven area.

What kind of nodules are you talking about?

Those are actually really common in any rocky area from Holland down to South Haven. There is a little park at Pier Cove(south of HOlland) with a walkway to the lake. From there you can walk the beach(as long as you stay along the waters edge, below the high wave mark) and find them by the bucket loads. I wanted some for an aquarium, so went over there today and filled a 3 gallon bucket with stones from an inch or two up to 6" in diameter, in about half an hour. Most are found just into the water, along the wave break line(There is a line of cobble stone running for as long as you wish to walk).

The owner of an art gallery in Calumet, MI, who is part Ojibway indian, told me that local Native Americans called the septarians "lightning stones", since the calcite-tilled cracks in them resemble lightning.

They polish beautifully.
