Blue Mineral at Adventure Mine
WWJ-Detroit shares that a bright blue mineral has been discovered at a mine on the Keweenaw Peninsula that so far has people perplexed:
The mysterious mineral was found on rock walls in the historic U.P. Adventure copper mine in Greenland Township, south of Lake Superior.
On Sunday, officials from the mine have posted pictures on Facebook of the mystery substance found on rock walls, but the bright blue material has not been positively identified.
Officials said they believe it to be a secondary mineral caused by a reaction with air and water. The mine operated from 1850 until 1920 and 11 million lbs. of native copper has been extracted.
Definitely visit the Adventure Mine website for information on their tours & the history of the mine. In the Facebook post referenced, Adventure Mine said “This bright blue mineral has not been positively identified as of this post but it is a secondary mineral that is caused by a reaction with air and water. It was found on the 3rd level in a small stope.” A stope is an excavation in a mine working or quarry in the form of a step or notch & the comment thread has some very interesting ideas as to what the mineral could be.
My own personal pet theory based solely on how cool it would be is that this reaction is due to the same mineral that creates the unique iron ore slag known as Leland Blue.
PS: After some discussion with Adventure Mine operators, I realize that I took my kids on a tour there 20 years ago. Super cool & a highlight of our visit to the awesome Keweenaw Peninsula – definitely put a trip to the copper-iest of Copper Country on your Michigan bucket list!
Banded Iron Formation by Linda Grashoff
Back in August of 2007, Linda & her husband took one of their many trips to Michigan’s Upper Peninsula & visiting Grand Marais, Ishpeming and Copper Harbor. She visited the Jasper Knob just outside of Ishpeming & writes:
It is a banded iron formation. The layers consist of jasper (the red rock) and hematite (the silvery rock). I’m delighted to tell you that some biogeologists believe that banded iron formations were formed by my old pals, the iron bacteria.
Head over to her photo blog for a lot more pictures and for sure check out her book They Breathe Iron for more about iron bacteria.

This is one of my photos that I dug up for another project that I wanted to share. Apparently this was taken during in my “tilty” phase. ;)
Here’s something beautiful that a young woman I know named Rose Petoskey wrote about Petoskey stones several years ago.
My name is Noozeen (Rose) Nimkiins (Little Thunder) Petoskey (Rising Sun) and I am Anishinaabek.
Many people would associate the word Petoskey with the souvenir stone found on the northern Lake Michigan shorelines. However, to my family, the word Petoskey represents much more than a souvenir.
In the Odawa language, the word Petoskey (Bii-daa-si-ga) means the rising sun, the day’s first light, or the sun’s first rays moving across the water. The Petoskey stone is a fossilized coral created by impressions made in limestone during the last Michigan ice age. These stones were named “Petoskey” because the impressions resembled the rising sun coming up over the water. Just as the image of the rising sun is implanted within the Petoskey stone, the archaeology of a person’s names is implanted within. All names within our Anishinaabek culture reflect an individual’s personal history. Rocks go deep, but names go much deeper to reveal the stories of the past.
Read on for more of Rose’s thoughts the power and beauty of the Odawa language!

PS: The other project was for a stone path that a friend is building this year at the Earthwork Harvest Gathering held next weekend near Lake City (September 16-18). It’s a wonderful festival packed with Michigan musicians!
Miner’s Castle before it fell, photo by spauldi1
Today is the 10th anniversary of the collapse of one of the turrets on the Miner’s Castle formation in the Pictured Rocks National Lakeshore.
On Thursday morning, April 13, 2006, the northeast turret of Miners Castle collapsed. One turret remains on Miners Castle, the best-known feature of Pictured Rocks National Lakeshore. The collapse was reported via cell phone by fisherman in the area, according to chief ranger Larry Hach. Most of the rock fell north and into Lake Superior, and there were no injuries. The lower overlook platform near Miners Castle appears to be unaffected.
While the rockfall at Miners Castle on April 13 was startling, such events are not rare along the Pictured Rocks escarpment.

As you may know, 2016 is my 11th year of making Michigan in Pictures. I really love doing it and am certainly going to keep it up as long as I am able. It does take a bunch of my time that might otherwise be spent working or getting out to see some of Michigan’s beauty, so I’ve been looking for a way to subsidize it that doesn’t involve ads, paywalls, or other annoyances.
Yesterday, I was reading a blog and saw they had a button to support them using a web service called Patreon. I checked it out, and it basically allows readers to become patrons of blogs they enjoy. Seemed like a great idea to me so I have set it up. If you’d like to donate a buck or more a month, I would very much appreciate it! Click here for my Patreon donations.
OK, on to today’s photo. Back in August of 2007, I was out walking with my friend Ken Lake on Frankfort beach. About a mile north of town we rounded a point and came upon a wondrous site – hundreds of balanced rock sculptures comprised of thousands of rocks. It remains one of the coolest works of art I’ve ever seen, and also a total mystery. I’ve still never heard who built these or why.

PS: Here’s a video I shot of these scene. The audio on this is kind of loud and crappy – sorry. ;)
