The Power of Green

We’ve Got the Power, photo by Ann Teliczan

I was just working on a simple post about Green Jobs Now, who have designated this Saturday (Sep 27) as a national day of action in support of jobs in renewable energy and other green industries so I could link to their list of Green Jobs Now Events in Michigan.

It got kind of out hand though, and ended up being a Renewable Energy linkfest of epic proportions that is now on Absolute Michigan.

As a side note, this lonely windmill just outside of Traverse City was the first utility windmill in Michigan and the largest machine in North America. As another side note, Ann has more great photos from the Leelanau/Traverse area right here!

Banded Iron Formation at Jasper Knob in Michigan

Banded Iron Formation

Alison writes that this formation is billions of years old and is the main evidence of showing when photosynthetic life first arrived on earth. This photo is part of her Fall set (slideshow) and you can order a copy online from Seneca Creek Photography.

UPDATE! Alison emailed me some great information that makes this a lot clearer!

The Banded Iron Formations (BIFs) are about 2 billion years old and are made of alternating layers of Magenetie (Fe3O4) or Hematite (Fe2O3) which are the grey shiny layers, and red layers of iron stained chert (SiO2) often called jasperite. This photo is part of the Negaunee Iron Formation. Fe2+ is soluble in water, but when iron is oxidized to Fe3+, it is insoluble in water and will precipiate and become a solid. So, the alternating layers represent Iron being oxidized, and precipitation out to form a red layer, and then iron not being oxidized so that you dont get precipitation and get a hematite layer. It is this cycle of there being oxic (oxygen present) and anoxic (no oxygen) conditions in the ocean that has scientists wondering how that could happen.

There are many models that have been put together of how this could happen, but the most interesting one says that ancient bacteria used to use iron as a nutrient. The first bacteria that photosynthesized on our planet produced oxygen, which could explain how the iron was oxidized, precipitated and formed the red layers. Some have said the layers represent the death and birth of algal blooms. Eventually, bacteria produced so much oxygen that all the iron was oxidized, and thus we don’t get BIFs forming in our oceans today since it is impossible to dissolve any iron in it. They even found bacteria in some of the BIFs in Minnesota!

-90% of the world’s BIF (>1014 tons of ore) is located in Australia (~ 27 tons), South Africa, Brazil, and the Lake Superior Region in the US and Canada. The iron that is mined in the UP is extracted from BIFs by grinding them to a powder, taking the iron out through magnets, adding bentonite clay, and then rolling it up into pellets more commonly known as taconite pellets.

She adds that she has some journals about these she would be glad to send to anyone interested, as she have done some research on these as well. Contact her through her web site!

Autumnal Equinox: the start of fall

Start of fall

Start of fall, photo by eric.whalen81.

The First Day of Fall article says that fall officially begins at September 22, 2008 at 11:44 am EDT. There’s some more information there including the reminder to put fresh batteries in your smoke detectors today!

Wikipedia’s Equinox entry says that equinox (from the Latin words aequus/equal and nox/night) can refer to the moment when the Sun is positioned directly over the Earth’s equator OR the apparent position of the Sun at that moment or the time at which the vernal point, celestial equator, and other such elements are taken to be used in the definition of a celestial coordinate system. Click through for much more Equinoxical information that appears in dire need of some editing for readability.

The outlook for fall on A Bright Spot Opposite the Sun relates:

Astronomers call Monday the autumnal equinox. Equinox means roughly “equal night”, which isn’t quite the case on Monday. The sun will rise on Monday at 7:34 AM and set at 7:41, making the day about seven minutes longer than the night. It isn’t until Thurs., Sept. 25 that the sun sets exactly twelve hours after it rises. On Monday, the day is a bit longer than the night because the sun is a disk, and sun rise and set are measured from the very top part of the sun. Anyway, it’s just a matter of minutes.

But on the equinox one thing is true: the sun rises due east and sets due west for every observer on earth. For us in West Michigan, where most of the roads are laid out east-west and north-south like the rulings on a sheet of graph paper, the equinox sun rise and set can be blinding on the commute to and from work. Take an extra pair of sunglasses with you in the car.

OK class, how about the Fall Color slideshow courtesy the Absolute Michigan group on Flickr??!!

it’s that time of year

Amy writes I like leaves year round, but I look like less of a lunatic taking pictures of trees in the fall.

I love leaves and trees too, and am always struck by the depth that autumn adds to the experience of being outdoors as trees suddenly become identifiable from a distance by their color. Hope you get out to see some of it this weekend!

Victory Eagle, Marshall Fredericks

"Victory Eagle" at Former Veterans Memorial Building--Detroit MI

“Victory Eagle” at Former Veterans Memorial Building–Detroit MI, photo by pinehurst19475.

Anthony Lockhart writes:

This monumental sculptural relief (twenty-eight feet tall) by Marshall Fredericks is on the north wall of what was the Veterans Memorial Building. It symbolizes both sacrifice and victory. The building is now the UAW-Ford National Programs Center. It was designed by the firm of Harley, Ellington and Day and dedicated in 1951.

He has many more statues & sculptures from Detroit (view slideshow)

Editor’s note: I’m always surprised when I find that I’ve never featured a photo from a photographer whose work I follow closely. This is one of those times – if you’re looking for architectural photographs of Detroit and the surrounding area with informed commentary … look no further.

Menominee North Pier Light

You can see more photos of this cool pier light (and see them bigger) in Lara’s Menominee slideshow.

Terry Pepper’s page on the Menominee North Pier Light (at the mouth of the Menominee River on Green Bay) says that after harbor improvements were completed in 1927:

… a prefabricated octagonal cast iron tower was delivered by vessel, and lowered onto the pier.

Click to view enlarged imageThe thirty-four foot tower was painted white, and integrated with an attached fog signal building. An elevated wooden catwalk stretched along the wooden pier to provide the keepers with safe access to the light during periods when waves crashed across the surface of the pier. The octagonal cast iron lantern room was outfitted with a Fourth Order Fresnel lens of unknown manufacture.

At some point thereafter, the wooden pier was replaced by a concrete structure with a forty-foot diameter circular crib at its offshore end. At this time, the fog signal was eliminated with the inclusion of an automated electrically operated signal in the tower. With automation of the light in 1972, the need for daily maintenance of the light was also eliminated, and the iron catwalk was removed from the pier.

Dave Wobster’s page on the Menominee Light has some great photos and says that the 10-sided lantern no longer contains the original Fourth-Order lens, which has been moved to the restored Sand Point Lighthouse in Escanaba.

Under the Falling Leaves Moon

Hunter's Moon

This weekend (September 18-20) they celebrate the Festival of the Falling Leaves Moon, which honors the the heritage of Mackinac Island’s Native peoples and the fall bounty.

Binaakwe-giizis is Anishnaabe (Chippewa/Ojibwe) for falling leaves moon. This moon celebrates the time of year when the trees were told to stay awake for seven days and seven nights and only the cedar, pine and spruce obeyed. As a reward the are ‘ever-green’ and those that were unable to stay awake must shed their leaves each fall.

The Falling Leaves Moon illuminates the remnants of the harvested crops which provided cover for animals during the growing season.

During the founding days of America, European farmers used the bright moonlight to hunt game, fish and gather rice while the Anishnaabe tribes hunted, fished, gathered and prepared to move to their winter camps in order to protect and sustain themselves through the long, cold winters in the Upper Midwest and collect furs for trade value.

Moons of Harvest and Hunters

Wikipedia says that the Hunter’s Moon is also known as Blood Moon or Sanguine Moon. It’s the first full moon after the Harvest Moon, which is the moon closest to the autumnal equinox.

Gagetown – Michigan’s Thumb Octagon Barn

John writes that this enormous, eight-sided barn in Gagetown is an agricultural museum open to the public during the warmer months.

Check out thumboctagonbarn.org for details including the answer to a question: Why an octagon barn?

Besides the fact that Mr. Purdy (the owner of the barn) was taken up by the uniqueness of this shape of barn, it was during this period that the agricultural community was promoting an octagon or round barn as the building of the future for agriculture. It was felt that this shape of building would be handier to work out of and that it would replace three or four buildings on the farm, i.e. hog house, horse barn, grainery, etc.).

At this same time Sears Roebuck & Co. listed a number of different sized octagon barn packages in their catalogue. You could order a barn “kit” and it was loaded on a flat car in Chicago and shipped all over the country.

It is obvious that if an octagon barn was the building of the future for agriculture there would have been more of them dotting our landscape. In talking to men who worked on the Purdy Farm as boys, they said that it was not as handy to work in and it was a more costly building to build.

Their photos page has some neat images including a photo of the Purdy Farm and barn from 1924.
