NORTHERN WISCONSIN -- In our previous post on the presence of asbestiform minerals in the Penokee range, we promised to "follow the rumor" that the mineral had been found at the mine site. Lots of phone calls to good people like Tom Evans and Esther Stewart of the Wisconsin Geological and Natural History Survey (WGNHS) plus interviews with concerned geologists, mining engineers and attorneys completed the story.*
We’ll come back to the rumor later. But first, I found that a lot of people, including myself, did not fully understand the geological reasons behind the occurrence of asbestos in the Penokee rock. So, briefly, here’s how it got there.
A Little Geology
The Gogebic Range resulted when tremendous forces broke the miles-thick crust of the earth and thrust our part up at a 60 degree angle. On Lake Road near Mellen, we can see a cross-section of this standing-on-end earth crust starting on the south with a small outcrop of some of the oldest rock on earth -- the first stable crust -- some 2.5 billion years old. Going north we see layers of rock that previously had accumulated at the bottom of a shallow sea -- the Palms formation. At a very sharply defined point the rock turns magnetic -- the Ironwood formation. A story, which could be another complete post, is that if you look at this slow accumulation of silt as kind of a clock of the life history of the earth, this instant where non-magnetic rock becomes magnetic rock is the exact time that modern life forms began on earth.
I digress.
In this photo the dark lines are "mafic" (lava -- probably gabro) intrusions into the lighter colored, fractured host material, a sedimentary rock of some kind -- not iron rich in this case. The arrowhead shaped feature at the end of the squiggly intrusion into a crack has some larger crystals which could be some asbestos-like material. (Photo © and courtesy Woodsperson blog)
The awful forces, strong enough to rend the crust of the earth, not only lifted the base to a 60 degree angle but, as you might imagine, shattered the layers of archaen crust and their overlaying layers of sedimentary (silty) rock. Cracks and crevices opened up and the underlying molten rock from lower in the crust oozed up in between the layers of shattered surface rock. This incredibly hot lava reacted with the iron and silicon and other elements in the rock to create metamorphosed new minerals. Some of those minerals cooled slow enough to form long or spiral or snowflake crystals of very high strength and high bulk density -- asbestos.
The geology lesson ends here. The result of this cataclysm is a random, chaotic set of asbestiform minerals scattered throughout the Gogebic range, being more prolific near the east and west ends of the range. Keep the chaos and randomness in mind as you read further. ...

Woodsperson: They’re doing it again!
Posted Aug. 4, 2013, on Woodsperson.blogspot.com
For more than a year geologists were saying that there were sulfides in the Ironwood deposit and in the Tyler Shale overburden. GTac (Gogebic Taconite) steadfastly denied that until they were presented with almost a hundred years of documentation that sulfides were there accompanied by the modern research done by Marcia Bjornerud of Lawrence University. Then GTac "debunked" that study by merely reimagining the size and topography of the deposit -- they just made it wider and steeper -- fixed! That resulted in the truly amazing testimony of Tim Myers and Bob Seitz -- the "tinytriangle of Tyler" testimony.
It appears that GTac is up to the same reality repair again....

Walk to drill site for proposed iron mine in Penokee Hills to be June 15
ASHLAND, Wis. -- The Penokee Hills Education Project invites friends and neighbors on a walk to the Gogebic Taconite (GTAC) drill site in the Penokee Hills, beginning at 1 p.m. on Saturday, June 15.

Exploratory drilling in the Penokee Hills, which is now underway, has been permitted by the Wisconsin DNR over specific objections from local citizens and the Bad River Band of Lake Superior Chippewa.
This walk is an opportunity to safely observe what test drilling looks like, firsthand, and to see how it impacts a pristine landscape. The walk will take place on lands that are open to the public, and the Penokee Hills Education Project encourages all walkers to obey the law and practice non-violence. The walk is approximately 3 miles through fairly hilly terrain. Be sure to bring your camera and bug spray! Persons of all ages are invited.
Directions: From Mellen, Wis., take Highway 77 east. Enter into Iron County and at approx. 8.75 miles from Mellen, turn right on Moore Park Road. Follow the road until you reach the "Road Closed" signs. Park on the RIGHT side of the road only.
The Penokee Hills are targeted by Gogebic Taconite (GTAC) for mountain top removal mining. This process would pulverize a 22-mile strip of the Penokee Hills and would release contaminants such as mercury, arsenic, other heavy metals, sulfates, sulfur dioxide, and nitrogen oxides into the air and water.
The polluted water would flow throughout the watershed, into the Bad River, threatening wetlands and sensitive ecosystems essential for the survival of the Bad River Band of Lake Superior Chippewa. The proposed mine would likely contaminate the drinking water for thousands of people living in Ashland and Bayfield Counties.

No taconite mine has ever operated without causing serious pollution.
The Penokee Hills Education Project was formed to educate the public about risks to the Bad River watershed and the Penokee Hills posed by GTAC’s mountaintop removal mine; to share relevant information about the impact of mining on our economy, health, and environment; and to connect with citizen-led groups locally, statewide, and nationally.

From Wisconsin Citizens Media Coop: State-wide opposition to Wisconsin mining bill grows
By Barbara With
Posted Feb. 26, 2013, on Wisconsin Citizens Media Cooperative
During a Feb. 25, 2013, press cbonference, a coalition of elected Wisconsin officials ask for state-wide support against the proposed SB1/AB1 Wisconsin mining bill, which the Wisconsin Senate is expected to take up today, Feb. 27.* (Photo © and courtesy Barbara With. Reprinted with permission.)
MADISON, WIS. -- On Monday, Feb. 25, the Bad River Band of Lake Superior Ojibwe called a press conference to demonstrate growing solidarity against SB1/AB1, the (Wisconsin) mining bill that would strip control away from local governments and exempt mining companies from having to abide by current air and water standards. Members of a coalition made up of area elected officials asked for state-wide support against a bill that will ultimately jeopardize all of the water in the state.
Ashland Mayor Bill Whalen summed up the group’s unified message: "This is not a Native Sovereign issue vs. the State of Wisconsin. This is a water and legislative issue that affects us all."
Bayfield Mayor Larry McDonald quoted the Lake Superior Binational Forum in expressing the intricate relationship of water to the area: "Water is life. The quality of water determines the quality of life. This is a world-wide issue."
Several members of other Wisconsin Tribal Nations spoke in support of Bad River and against the bill. Rose Soulier from Red Cliff shared the message she personally gave Governor Walker: "In November, at a Tribal quarterly meeting with the Governor, I asked that he consult with all Tribal Nations and not shove this mining bill down our throats." She added, "Well, that never happened. We’ve been choking back our tears ever since." Click here to read the rest of this article and learn more about this issue on the Wisconsin Citizens Media Cooperative Web site.
* Editor's Update: Barbara With concludes that the Wisconsin Senate is expected to take up the bill today, Feb. 27. If it passes out of the Senate, the Assembly is projecting a March 6 date to take a vote for final passage. She notes on Facebook that many communities in northern Wisconsin are opposed to this bill, written to facilitate the proposed Penokee open-pit mine. The Senate debate on the bill may be on live stream beginning at 11 a.m. TODAY, Feb. 27, at http://www.wiseye.org

Penokee Hills Rich in Natural Wonders and Human History
By Margaret Comfort and Steve Garske
A delightful and educational afternoon was had by all during a mid-August hike in the Penokee Hills east of Mellen, Wisconsin. The trip was organized by the Northwoods Native Plant Society (NWNPS), and led by local botanists Ian Shackleford and Steve Garske. Also on hand to help guide us was Sherry Zoars, NWNPS coordinator (1).

The hike began along the Tyler Forks River. This legendary river officially comes into being at O'Brien Lake, south of the Penokee Range. As it flows south and west, the river is fed by wetlands and streams. It then abruptly turns north towards the Penokee Hills. By the time it makes its way to the big hill we were about to visit, it has become a substantial river (and a Class II trout stream). Having heard reports of a canyon on the river, we followed a well-worn path leading upstream. A short walk brought us to the enchanting spot pictured above, with low waterfalls and a very picturesque vertical-sided gorge.
We then headed up the hill. A short walk along an old logging road through mature sugar maple forest brought us face-to-face with a bit of area history: the remnants of the original Tyler's Fork iron mine. The Tyler's Fork mine was named after Captain T. F. L. Tyler, an early minerals explorer in what is now the Mellen area.
According to local author and historian Bruce Cox, iron ore was discovered at this location around 1856 by a Mr. Latham. A "practical mining man" named Angus McDonald verified the ore body soon afterwards, but was called away and didn't return until 1888. Development of the mine began around this time. Two shafts were sunk to 225 and 300 feet, a railroad spur was built, and the mine began shipping ore two years later. The mine employed up to 200 men and shipped about 60,000 tons of iron ore before being abandoned in the late 1800s. In 1907 an attempt was made to reopen the mine, but low iron prices combined with the fact that the spur line had been removed shafted the attempt (2).
Today one can still see the rock foundation of the old hoist engine, as well as waste rock piles, now overgrown by balsam fir. A series of exploration pits is also still evident.

A row of exploration pits can be seen at the old mine site.
The Tyler's Fork mine site is a vivid reminder of how the scale of industrial mining has changed. The entire site of the old mine, including waste rock and ore piles, occupies less than 1 percent of this 4.5-mile long hill that would be "Phase I" of the proposed Gogebic Taconite (GTac) open pit iron mine. Should this mine be built, by the time this phase was completed this entire hill would be gone and an open pit 4.5 miles long, up to 0.6 miles wide and more than 900 feet deep would take its place. The overburden and waste rock would be piled on Iron County lands to the south, forming a massive pile of rubble the size of Rib Mountain (near Wausau, Wisconsin), according to calculations by independent geologists. Cartographer Carl Sack has created a detailed map of all this (3: See link below to download map).
After visiting the old mine site, we followed an old two-track logging road west, along the north side of the hill. On each side of the road we were flanked by mature hardwood forest interspersed with seeps and wetlands. Pink flagging hung from branches along the south side of the road, marking the locations where the GTac company had applied for a permit to drill boreholes to characterize the deposit. On March 15, 2011, GTac applied for a permit to drill eight exploratory holes (4). The Wisconsin DNR issued the permit a few days later (5). Then in early June 2011 GTac announced that they would probably need to drill as many as 30 holes to characterize the site (6). But soon afterwards, GTac put the entire project on hold until the state's mining law was changed, and none of the holes were ever drilled (7). The pink flagging marking the locations for the prospective holes still hangs from the trees.
Flagging marks the location of a potential drill hole for the open-pit iron mine planned by Gogebic Taconite in 2011.
Along our walk participants pointed out some of the botanical treasures that light up the summer woods. Fringed loosestrife (Lysimachia ciliata) is an attractive and little known native wildlflower that favors wooded seeps, floodplains and wetland edges. It spreads underground to form a carpet on moist to wet, lightly to moderately shaded sites, and makes an excellent border or wildflower planting. Tall sunflower (Helianthus giganteus) grows in similar habitats (usually in light shade to full sun though), and is one of our choice late summer wildflowers. And nodding trillium (Trillium cernuum) was busy making seeds.
Sundrop-like flowers of fringed loosestrife brighten our path.
You're not so tall, Mr. Sunflower! On sunny, moist sites tall sunflowers can reach more than seven feet tall.
Nodding trillium with its bright red seed capsule.
Starting around 1958, renewed interest in iron mining led to 233 cores being drilled in this part of the Penokee Range, including some along this hill. We saw several of the old holes during our walk. An interesting article by Deanna Erickson relates a tour of the area by state senators and local officials in 2006 and mentions these cores (8).
A fellow hiker checks out an exploration hole along the crest of the hill.
The Penokee Hills and the wetlands to the south form the headwaters of a large number of streams and several major rivers. These include Ballou Creek, Bull Gus Creek, the Tyler Forks River, and the Bad River. The main branch of the Bad River begins at Caroline Lake. From there it makes its way north to Copper Falls State Park. The Tyler Forks River also flows to the Park, before cascading over spectacular Brownstone Falls and into the Bad River. The Bad River continues its journey north, flowing through the Bad River Reservation and eventually reaching the Kakagon-Bad River Sloughs and Lake Superior. The Kakagon - Bad River Sloughs support what may be the largest and most pristine wetland complex on the Great Lakes. That complex supports what may be the largest and most productive wild rice beds in the world. These rice beds are an irreplaceable cultural and economic resource for the Ojibwe people. The sloughs were designated a National Natural Landmark in 1973. All together, about a dozen lakes south and west of the proposed mine site and more than 24 streams and rivers running through the site would be impacted by the mine (9).
Much of the concern about the environmental damage from the proposed mine has focused on the region's lakes, rivers, and streams. These risks are substantial -- including increased sedimentation; lowering of the surrounding water table; and acid mine drainage, which would carry acidified runoff and toxic heavy metals downstream towards Lake Superior. But less attention seems to have been given to the forests and wetlands that would be obliterated if this mine were to proceed.
The Penokee region supports some of the healthiest and most productive northern hardwood forests in the state. It forms a natural corridor of forests and wetlands joining the Chequamegon National Forest in northern Wisconsin to the Ottawa National Forest in western Upper Michigan. And many consider it one of the most scenic areas of the state as well.

On March 6, 2012, the Wisconsin State Senate declined to pass the House mining bill (widely understood to have been written primarily by GTac) by one vote, with all 16 Democrats and Republican Dale Schultz of Richland Center voting against the bill. Within hours the GTac president announced that the company was "leaving Wisconsin." The company continues to linger in the shadows, though. A letter from the Wisconsin Manufacturers and Commerce (WMC) (leaked to Progressive Magazine) outlines WMC's strategy of waiting for a Republican-controlled senate in November to push GTac's bill through (10). And a recent Ironwood Daily Globe article quotes GTac president Bill Williams as saying that the company is still considering the area (11).
For millennia the Penokee hills have towered above the surrounding landscape, the worn-down roots of an ancient mountain range that was once as high as the Rockies are today. A billion years of wind, rain, freezing temperatures and glaciers have not been able to erase them from the landscape. But the final chapter in their history has yet to be written. What will be left of the Penokees 50 or 100 years from now? Their fate is in our hands.
