mLive reports that a La Niña weather system has officially developed & is likely to continue through winter:

La Niña is when the equatorial Pacific waters turn cooler than normal. If the cooler than normal water continues into the northern hemisphere winter, there can be some alteration to normal jetstream patterns.

…an average jetstream position south of Michigan with the center of an upper-level through over the Great Lakes brings an area of wetter than normal conditions to the Ohio Valley and southern Great Lakes. This area of wetter weather includes the southern part of Michigan.

So in looking at the general effects of La Niña on Michigan’s winter, we have in the past leaned toward colder than normal with some increase in snow amounts.

…Lower Michigan as averaging four to 12 inches above normal on snowfall during La Niña winters. The western half of the U.P. also shows a slightly above normal snowfall pattern during La Niña. The lake-effect snowbelts of northwest and southwest Lower don’t show an increase in snow, but do show normal amounts. Normal amounts of snow in the snowbelts is plenty of snow for snow-lovers.

TBT: Columns of Ice at the Eben Ice Cave

Eben Ice Caves March 19, 2007

Columns of Ice, Eben Ice Cave, photo by John Clement Howe.

EDITOR’S NOTE: With the rise of coronavirus, it seems to me that we could all use a little reconnection with our lovely state of Michigan, so I’m going to try to dig out some old photos and share some new ones to help keep you close to Mama Michigan as you socially distance!

This photo originally appeared March 20, 2007 and is one of a nice set titled At the Ice Cave of Eben taken in March of 2007 at the Eben Ice Caves in the Upper Peninsula near Munising. My friend Dr. John Anderton of the Northern Michigan University Department of Geography who has since passed away explained their formation:

The Eben Ices Caves are located just a few miles north of the little town of Eben, within the Rock River Canyon Wilderness Area (RRCW). The RRCW, which became a Wilderness in 1987 as a part of the Michigan Wilderness Act, is located approximately 15 miles west of the town of Munising, MI, within the Munising Ranger District of the Hiawatha National Forest. It comprises 4,460 acres and contains outstanding natural features including Rock River, Silver Creek and Ginpole Lake. Within its interior there are two short user-developed trails (totaling about 1.75 miles) leading to Rock River Falls and the Eben Ice Caves. An estimated 1,700 people visit the area annually (USFS records) …

The Ice Caves are not true caves at all. They consist of walls or vertical sheets of ice that form across the face of overhanging rock outcrops. In the summer, small unimpressive waterfalls and groundwater seeps may found along the overhangs. In the winter, however, the water hits the cold air, drips downward under the influence of gravity and freezes, creating spectacular ice caves. Each winter they look a little different, but typically there are openings in the ice that allow you to walk behind the ice walls.

The rock overhangs, where the ice caves form, consist of outcrops of Munising Formation (Cambrian) with a capstone of AuTrain Formation (Ordovician). The outcrops are found along the south side of the valley of Silver Creek, which is part of a network of secondary glacial drainage channels that formed during the Marquette Advance (about 10,000 years ago). Theses secondary drainage channels flowed easterly into the AuTrain-Whitefish Channel, a primary glacial meltwater channel that flowed south to the Lake Michigan basin. Groundwater naturally seeps from these rocks, providing the water necessary to form the ice caves in the winter.

Blue Ice at Bay City

Bay City Blue Ice, photo by Great Lakes Drone Works

Great Lakes Drone Works captured some awesome shots from the ice on Saginaw Bay near Bay City. They write:

We made our way out to Bay City State Park to capture some images of these huge chunks of ice. At first we were hoping drone photos would be the way to go but after walking around and getting up close, it was clear that ground photography was the better option.
Blue ice occurs when weather conditions — such as a lack of high winds — allow water to freeze slowly and evenly, resulting in ice composed of large crystals (unlike snow, which is formed quickly and made up of small crystals).

When light hits these big ice crystals, it can travel deep into the structures (compare this to snow, wherein light hits a sharp edge and reflects off of it right away, resulting in blinding white). When the light travels deeper into slowly formed ice, some of the red wavelengths of sunlight — which is the longest wavelength of visible light — get absorbed into the ice structure.

The blue, which is the shortest wavelength of visible light, bounces back out, meet our eyes, and results in a deep aqua color.

The Colors of Cold

Green Blue Ice, photo by Charles Bonham

Apparently Charles is my go-to photographer for ice colors as his picture was used for my post about what makes ice blue or green a couple years ago on Michigan in Pictures. Then as now, I went to The Causes of Color to answer the question: What causes the blue color that sometimes appears in snow and ice?

As with water, this color is caused by the absorption of both red and yellow light (leaving light at the blue end of the visible light spectrum). The absorption spectrum of ice is similar to that of water, except that hydrogen bonding causes all peaks to shift to lower energy – making the color greener. This effect is augmented by scattering within snow, which causes the light to travel an indirect path, providing more opportunity for absorption. From the surface, snow and ice present a uniformly white face. This is because almost all of the visible light striking the snow or ice surface is reflected back, without any preference for a single color within the visible spectrum.

The situation is different for light that is not reflected, but penetrates or is transmitted into the snow. As this light travels into the snow or ice, the ice grains scatter a large amount of light. If the light is to travel over any distance it must survive many such scattering events. In other words, it must keep scattering and not be absorbed. We usually see the light coming back from the near surface layers (less than 1 cm) after it has been scattered or bounced off other snow grains only a few times, and it still appears white.

In simplest of terms, think of the ice or snow layer as a filter. If it is only a centimeter thick, all the light makes it through; if it is a meter thick, mostly blue light makes it through. This is similar to the way coffee often appears light when poured, but much darker when it is in a cup.

Candle Ice on Lake Michigan

Yesterday my photos and videos of an odd phenomenon on the Lake Michigan shore in Leelanau County got featured by Tanda Gimter on mLive who writes in part:

…some of the ice-crystal creations that suddenly appeared on a Leelanau County beach last weekend had photographers excited about their find – and a little baffled. The large, column-like crystals spread out on the ground like blooming flowers.

When you touched the hand-high columns, they broke apart easily.

“It was just kind of a weird day,” said Andrew McFarlane of Leland, who works in web development and marketing. He took pictures and a couple videos of the phenomenon while he was at Van’s Beach in Leland on Sunday. “I’ve never seen it before that I can remember.”

As regular readers know, I’m not one to let a Michigan mystery alone, and after some research I’m pretty confident that this is called “candle ice”. The American Meteorological Society defines it as: A form of rotten ice; disintegrating sea ice (or lake ice) consisting of ice prisms or cylinders oriented perpendicular to the original ice surface; these “ice fingers” may be equal in length to the thickness of the original ice before its disintegration.

Here’s a video of it!

Walking on Water, Michigan Style

Walking on Water, Michigan Style by Andrew McFarlane

Here’s a shot I took while standing on the amazingly clear ice on Lake Michigan’s Suttons Bay on last Saturday with my sweetheart! mLive liked it enough to share in their article about Grand Traverse Bay freezing over (Suttons Bay is a “sub-bay” of GT Bay – here’s a map):

“Back in the early to mid-1900s the bay froze 80-90% of the time,” said Heather Smith, Grand Traverse baykeeper for the center. “Around 1990, ice cover dropped to 20-30%.”

This winter is the eighth time Grand Traverse Bay has frozen over since 1990.

The frozen conditions likely extend far beyond Power Island, at least close to shore. Last weekend, ice boaters, ice fishermen and people walking their dogs flocked to the frozen surface of Suttons Bay for some winter fun.

Grand Traverse Bay is divided neatly by Old Mission Peninsula into its East Arm and its West Arm. Its East Arm runs north of Elk Rapids, while its West Arm includes the popular Power Island and extends to Suttons Bay.  From there, the bay curves around the Leelanau Peninsula where it merges with Lake Michigan.

Happy Valentines Day everyone!!
