Posts Tagged ‘Pancake Ice’

One of the things I’ve seen (or felt) this time around is cold, and lots of it. The record cold of the second week of November came as quite a shock after the record warmth of the first week of the month. I was surprised when I found these frost crystals on my windshield one morning.

Ice needles by the thousands thrust up out of the saturated soil near a stream. An awful lot of things have to come together perfectly for ice needles to form. First, there has to be groundwater present and the temperature right at the soil surface has to be below 32 degrees F. The groundwater remains thawed until hydrostatic pressure forces it out of the soil, where it then becomes super cooled and freezes instantly into a needle shape. As more water is forced out of the soil it freezes at the base of the needle and it becomes longer and longer. As this photo shows there are often so many needles that they freeze together and form ribbons. Each needle is hexagonal in shape and the longest one ever found was over 16 inches long. These examples were probably 3-4 inches long.

This is what soil with ice needles growing in it often looks like from above, but more important is the crunching sound the needles make when you walk on them. More often than not I find them by sound rather than by sight. They are very fragile and break easily, and if just the merest hint of sunlight falls on them they melt, so look for them in the shade.

Ground water seeping out of stone ledges formed icicles and that reminded me that it’s almost time to visit the deep cut rail trail in Westmoreland, where the icicles grow into ice columns as big as tree trunks.

Ice isn’t the only thing we’ve seen here lately. The first real snowfall measured an inch or two in some places. This is what my ride to work looked like early one morning. When snow falls on thawed ground it melts rather quickly. The soil doesn’t usually freeze here until December, but it can vary. In a cold winter with little snow it can freeze down to nearly four feet deep.

The snow was on the wet side rather than dry and powdery so it stuck to every single twig and stalk in the forest. One of my favorite quotes by Scottish author William Sharp says “There is nothing in the world more beautiful than the forest clothed to its very hollows in snow. It is the still ecstasy of nature, wherein every spray, every blade of grass, every spire of reed, every intricacy of twig, is clad with radiance.” I agree, and that’s what this day was like. You don’t just see beauty like this. You feel it—you give yourself to it, and it becomes part of you.

At the Ashuelot River ice baubles formed on overhanging shrub branches. They are very colorful in the sun and it looks like someone has hung prisms from the branches the way they flash different colors.

As the river water splashes up onto a twig, drop by drop a teardrop shape (usually) forms. The ice they’re made of is as clear as polished crystal, and very reflective.

There was pancake ice in the river below the falls. It forms from the foam that the falls create. The foam becomes slushy and breaks into small pieces and freezes, and the current spins the irregularly shaped pieces into more circular shapes.

The constantly moving circles of river foam bump into each other and form rims, and they start to look like pancakes. Most are about the size of a honeydew melon but they can be bigger or smaller. From what I’ve read pancake ice is rare outside of the arctic but I see it here (and only here) every winter. In the arctic these frozen “pancakes” can pile on top of one another and in some areas 60 foot thick ridges of them have formed. Here though, they simply float off down the river.

White ice, so I’ve read, has a lot of oxygen in it. It is paper thin and tinkles when it breaks and I usually find it on mud puddles, but only at the start and end of winter. I love it because it always reminds me of spring, and that’s when I used to ride my bike through puddles of it when I was a boy.  You can see some amazing things in this ice. I’ve seen everything from eagle silhouettes to solar systems in it.

This is something I’ve never seen. The foam in a stream froze into formations at the base of a tree and they looked remarkably like turkey tail fungi (Trametes versicolor.) My thoughts on what kind of currents it took to make them would be a guess but maybe the stream water splashed against the roots and created ripples of foam, and then the foam froze as the ripples left the shore.

Speaking of turkey tail fungi, I’ve seen some beautifully colored examples this year. Turkey tails are among the most colorful fungi and also one of the easiest to find, and they grow in nearly every state in this country and throughout Europe, Asia, and Russia.

Their colors are described as buff, brown, cinnamon, and reddish brown in mushroom books but they come in many more colors than just those. Blue and purple are two of my favorite colors, but turkey tales wearing those colors are rare in my experience. I probably see one blue one for every five hundred brown ones.

Their concentric bands of color are what make turkey tails so beautiful but beauty isn’t all they have going for them. They’ve been used medicinally in China for thousands of years and in this country the food and drug administration has approved them for cancer treatment trials.

I saw some strangely colored but beautiful trumpet shaped mushrooms on a dead elm tree. I think they were frozen solid. Maybe that’s what made them so beautifully colored.

We’ve had a year with more cones on the evergreen trees than anyone has ever seen before. Great bunches of them weighted down the uppermost branches of the white pines (Pinus strobus) until they finally opened, dropped their seeds, and fell to the ground by the thousands. I decided to check into why there were so many and it turns out that the drought of 2016 has a lot to do with it, because that’s when the cones actually formed. Often, when a plant is stressed out enough to “think” that it’s dying it will produce larger than normal amounts of seed to ensure the continuation of the species, and it looks like that is just what our evergreen trees have done. Every single person I’ve talked to says that they have never seen so many cones.

Unfortunately something else that has been very noticeable to everyone is the sticky sap, called pitch, which has been falling from the white pines. It has gotten all over everything and is very tough to clean off. You can’t sit at a picnic table without sticking to the benches and you can’t drive your car down the road without finding large gobs of sticky pitch all over it. I’ve had to clean it off my car twice now and I can say that it doesn’t come off easily. The above photo is of a log with gobs of pitch all over it. As it dries the pitch turns white and as the weather cools and the pitch ages it often turns a bluish purple color. Turpentine is made from the resin of pine trees, and turpentine is just about what it takes to get it off.

The inner bark of this fallen Scots Pine (Pinus sylvestris) was so intricate and beautiful all I could do was stand and stare. And when I came back to my senses I remembered to take a photo.

As I hope this post has shown, even after the flowers have gone and the leaves have fallen there are still plenty of beautiful things to see out there. All of the beauty we don’t see in the warm months seems to be amplified or magnified in the cold months. The crisp blue of the sky, the golden light of the rising and setting sun, the greens of the mosses; all seem more vibrant. Even stones can be beautiful, as this one was. I don’t know what was in the geologic soup that it came from but it’s very different than most other stones in this area and very beautiful, and I found myself wishing it could come home with me.

Last year I must have driven to my favorite mountain viewing spot to see if there was snow on Mount Monadnock at least four times before I finally saw it snowcapped but this year there it was, and I took this photo on my way to work one morning with no extra effort at all. As a bonus a bald eagle flew by but it was far too fast for a photo. Though it looks like Dublin Lake in the foreground was frozen over it wasn’t. The sun hadn’t come up yet and I think it was just the low light that made it look that way.

By the time I had driven to Hancock the morning sun was just kissing Monadnock and turning the scattered patches of snow to gold. Mist gathered in the valley below and the scene was so beautiful I almost forgot I was on my way to work. When the sun rises or sets change happens quickly and it’s hard to pull yourself away.

Thanks for coming by. I hope everyone here in the U.S. has a safe and happy Thanksgiving Day tomorrow and don’t forget; a walk in the woods is a great way to burn off all those extra calories.

1. Winter Woods

After more than 3 months of warmer than average temperatures we’ve finally had a real taste of winter here, with a few inches of snow and a couple of days and nights of bone chilling cold. The cold I could do without but it’s hard to imagine anything more beautiful than freshly fallen snow decorating everything in the forest.

2. Hemlock

Eastern hemlock (Tsuga canadensis) branches catch so much snow that there is often bare ground under them a day or two after a storm. That’s why white tailed deer bed down under them. Years ago when I smoked I used to stand under a big old hemlock in the front yard when it rained, and even in a downpour barely a drop of rain reached me.

3. Morning Clouds

I don’t know what it is but there is something about the hill on the far side of Half Moon Pond in Hancock that seems to attract sunshine. I have no way to explain what I’ve seen here but even on cloud covered days the clouds will often part to let the sun shine on it. I hope to climb it one day. Maybe the sun will shine while I take photos for a change.

4. Half Moon Pond at Sunrise

This photo is deceiving because even though the sun had just risen above the hills behind me it looked like it was rising behind the hills in the distance. It’s one more thing I can’t explain about how the light and shadows play on Half Moon Pond and the hills that surround it. Odd things happen here. This photo was taken in January just as the pond had frozen over, and what looks like water in the distance is actually glare ice.

5. Cattails

Wind plays a big part of winter and it can often mean the difference between bearable and unbearable temperatures, but how do you show it in a photo? This is one way; the prevailing winds showed these cattail leaves which way to grow.

6. River

Some see winter as dark and bleak and colorless, but there is much color and beauty to be seen if they’d only look around a little. I love how the white snow makes water look so inky black. If it hadn’t been so cold I could have stood there longer, admiring it.

7. Sunrise

The sun promised a warm day but it was a bitter cold morning when I stopped to get a shot of it with my cell phone. It did turn out to be a warm day in spite of the morning cold, though. In fact most of them have been on the warm side this winter, but not all; we’ve seen night temperatures drop to -15 ° F (-26 ° C.) Interestingly on this, one of the coldest mornings of the season, I heard the sad but beautiful Fee Bee mating call of the male black capped chickadee. Now I’m sure that spring is just around the corner, no matter how much more winter we see.

8. Ice Finger

When the water level of the river dropped it left a skirt of ice around this stone. Then the sun warmed the stone and the ice skirt melted into an icy finger that reached around it from its back side. I’m sure the icy finger had to attach to the stone somewhere, but it wasn’t anywhere that I could see. It must have been on the far side which I couldn’t get to because the river was so close.

9. Ice Finger

Another view of the icy finger, which looks to be just about ready to tickle the stone.

10. Canada Geese

Canada geese don’t seem to mind the cold. They appear to act the same, winter or summer, though I usually see them in flocks rather than pairs.

11. Canada Geese

As usual one stood guard while the other fed.

12. Ashuelot Falls

The stones at the base of Ashuelot Falls in Keene were ice covered, but since it was only about 15° F, I wasn’t surprised.

13. Ice Pancakes

Downriver from the falls ice pancakes were frozen into the ice covered surface. This view also shows the needless cutting of all the shrubs along the riverbank, most of which were silky dogwoods that robins and cedar waxwings enjoyed eating the berries from. The same thing happened last summer along the Ashuelot in Swanzey. I think this is driven more by ignorance than for any other reason, but I didn’t know that this kind of ignorance was so widespread.  I’ve heard that the Army Corps of Engineers has been here studying the dam for possible removal so the bank clearing might have something to do with that, but why they would need to cut everything so far from the actual dam is a mystery.

14. Ice Pancakes

Ice pancakes, according to Wikipedia, can grow to nearly 10 feet in diameter and can have a thickness of nearly 4 inches.  Each pancake has an elevated rim that forms when the frazil ice or slush that it is made from bumps up against other pancakes. Since these one foot diameter examples were frozen into the river ice I think they were done bumping together, at least for now.

15. Ice Formations

Since these formations didn’t have raised rims I’m guessing that they weren’t pancake ice. They looked more like paving stones.

16. Ice on Ice

I saw a kind of ice that I’ve never seen before. What I can only describe as light colored frost feathers grew all over the darker ice of a stream.

17. Ice on Ice

This is a closer look at the frost feathers from a photo taken with my cellphone. I wonder if anyone has ever seen something similar. Many of them stood vertically on the ice of the stream. I can’t imagine what caused them to form unless it was very high humidity on the surface of the stream ice.

18. Stone Frozen in Ice

A stone was trapped in the ice near the formations in the previous shot but since it probably wasn’t going anywhere I doubt that it cared. It’s interesting how the sun seems to warm some stones enough to melt the ice on them but others stay coated in it.

19. Puddle Ice

Nature laid the universe at my feet but I was too blind to see it until I looked at the photo I took of this puddle ice. It was only then that I saw the stars, asteroids, galaxies and distant nebulae, almost as if I was looking at a photo taken by the Hubble telescope. As Edward Abbey once said: There is beauty, heartbreaking beauty, everywhere. To that I’ll add: Even in mud puddles.

20. Sap Bucket

So far this winter has been an upside down one; warm enough to get sap flowing and witch hazel blooming before a bitter below zero cold snap and then 50 degrees and rain yesterday. When spring finally does get here there’s no telling how plants will react to such an overall warm season. My feeling is that they’ll be fine, but we’ll have to wait and see.  The first thing nature teaches is patience.

There is nothing in the world more beautiful than the forest clothed to its very hollows in snow. It is the still ecstasy of nature, wherein every spray, every blade of grass, every spire of reed, every intricacy of twig, is clad with radiance. ~William Sharp
