Posts Tagged ‘ice shelves’

Well, we survived the coldest stretch of weather I’ve ever seen and now we’re in the midst of a January thaw, but I didn’t think I’d ever thaw out after going out on January 7 th to take many of these photos. It was a brisk 14°F but the sun was shining and I didn’t think it would be too bad, but it still felt frigid because of a breeze. Anyhow, anyone who lives here would know how cold it must have been just by seeing this photo of the Ashuelot River in Swanzey frozen from bank to bank. I think this is the first time in two or three years that this has happened.

Downstream from the previous photo ice shelves were forming but the river was open.

You could see how much ice had formed since the last snow. But the last snow was just 3 days before this photo was taken.

Close to a foot of snow fell and plowing it made mountain ranges.

After the snow storm dragged down more arctic air it got even colder; too cold to be outside for more than just a few minutes.

On New Hampshire’s tallest peak Mount Washington, a tie score for the second coldest place on the planet was recently recorded. At -36 ° F. with a wind chill of -94 °F. it was just two degrees warmer than Yakutsk Russia. What an honor.

Birches bent under the weight of the snow, which fell on top of the ice from the December ice storm. It has been so cold that the ice from that storm weeks ago has never melted.

The birches were giving up their seeds to the wind and to the birds too, probably.

Birds are definitely eating the seeds from eastern hemlock (Tsuga canadensis) cones. Chickadees, pine siskins and other small birds eat them, and several species of warblers nest in the dense foliage. Larger birds like turkeys, owls, and grouse will often roost in the branches, possibly because hemlocks are excellent at shedding water. You can stand under large hemlocks in a pouring rain and barely feel a drop. Deer will eat the foliage.

By September the small cones and seeds of eastern hemlock are ripe but are still green, wet and oily. Once the cones begin to turn brown the seeds will be dry and birds can get at them as soon as the cone opens like the one pictured. Hemlock seeds are often lacking in viability, with less than 20% of them viable. Hemlock trees can live to 800 years old and reach a height of 175 feet. Native Americans used the inner bark, roots, and needles of hemlocks medicinally. They contain antiseptic properties and were used to treat wounds and in sweat lodges to treat colds and rheumatism. When food supplies were low the inner bark was often eaten.

Bird tracks under the hemlocks reveal their value to wildlife.

The birds have eaten all the coneflower (Echinacea purpurea) seeds. Since these coneflowers were mostly planted by the birds the seeds belong to them and I don’t cut them or other plants back until spring. The more seeds they eat and spread around the yard, the more plants I’ll / we’ll have.

A motherwort (Leonurus cardiaca) stem poked up from the snow and I thought it was interesting how I could see where all the little tufts of tiny flowers had been much easier without its leaves in the way. Of course the flowers are now seed pods. Though I’ve searched to find out which birds eat the seeds of motherwort I didn’t have any luck at all. It could be because the plant isn’t native, coming originally from Asia. It was brought here because of its long history of medicinal use in Europe and Asia. It is said to be useful as a heart medicine, hence the cardiaca part of its scientific name. It has a sedative effect and is also said to be useful to treat anxiety and muscle spasms.

The ice on most lakes and ponds is safe now, probably thicker than it’s been in years, and fishermen have begun setting up their bob houses. Some of these small, garden shed size buildings are quite elaborate, with all the comforts of home included. This fisherman built his out of clear corrugated plastic, probably hoping for some solar gain. I’d have to want to catch a fish pretty badly to stand on the ice all day, even if it was in a bob house.

When you approach a frozen over pond with snow covered ice you often can’t tell where the land ends and the water begins, so I look for cattails (Typha latifolia.) They always tell me right where the water starts.

Japanese knotweed stems (Fallopia japonica) looked red in the bright sunshine. It’s too bad this plant is so invasive, because it is pretty through much of its life cycle.

Milk white toothed polypores are resupinate fungi, which means they look like they grow upside down, and that’s what many crust fungi seem to do. This is a common winter fungus with “teeth” that are actually ragged bits of spore producing tissue which start life as pores or tubes and break apart and turn brown as they age. This fungus can be found on the undersides of hardwood tree branches. They don’t seem to mind the bitter cold temperatures we’ve had.

When I was in high school I had an art teacher who knew how to paint winter scenes. She taught me how to paint snow on tree branches and have it look realistic, and how to paint snowy landscapes. She was a professional artist as well as a teacher so she knew her way around an easel, but I still questioned her when she said that my gray winter shadows should be blue. I told her I painted them as I saw them, and I saw gray. I don’t know if it was colorblindness or some other reason that I saw gray but whatever it was has corrected itself and now I see blue winter shadows, just as Miss Safford said they should be. What makes them blue? The ice crystals that make up the snow reflect the ambient blue light from the sky. The color of a shadow is determined by the amount of light reaching the area that is in shade and light from the blue sky will even illuminate shaded areas. If the sky is gray, the shadows will appear gray.

It was so cold on this day that even the window frost seemed contracted, like each crystal had been held back by an icy grip, so instead of large, elaborate and beautiful frost feathers what formed were blocky, clunky crystals.

Here is an extreme close up of some window frost crystals. They didn’t have the beauty of frost feathers but this example reminded me of Aztec and Inca carvings I’ve seen photos of. It looks like a figure with a headdress, a long nose or beak, and wings. Or maybe it just looks like ice. I’ll let you decide.

For the first time in almost eight years the weather has brought this blog to a screeching halt. Since Christmas we’ve had dangerously cold temperatures, with the lowest reading at my house -20°F below zero (-29 C.)  Add to that howling winds and the temperature can easily be in the -30s below zero range. Flesh can freeze in about 15 minutes in those conditions so I haven’t been outside to take photos in nearly 2 weeks now. In my lifetime I’ve never seen such extreme cold last for so long without letup. It is for these reasons that I offer up a post I did on the “blizzard” of 2015 on January 31st of that year. They say we’ll see a real January thaw this week with temperatures above freezing almost all week, so things should return to normal soon.  I hope.

I’m sure by now everyone has heard about the blizzard of 2015. While it’s true that a small piece of New Hampshire coastline did see blizzard conditions, in my yard I had trouble finding snow that was 6 inches deep. That might not be entirely accurate though because the real story was the gale force wind that blew the powdery snow every which way and made you feel as if you were in a snow globe.

So how do you tell the story of wind on a blog? Showing wind sculpted snow is one way.

The wind can do some fantastic things with snow, including sculpting snow waves.

Here is the snow wave in the previous photo, shot from a different angle. It seemed odd that a 4 foot deep snow drift would form in the middle of an open field, but that’s what happened here.

Another part of the story is the cold. For the last two winters January has seemed a very cold month indeed, but at least this year the Ashuelot River hasn’t frozen over at my favorite viewing spot in Swanzey. The only remarkable thing about this photo is what it doesn’t show; there have always been Canada geese in this spot but last year when the river froze from bank to bank they left and haven’t come back.

The rocks in the river show a layer cake like history of winter’s ice and snow storms.

Ice shelves are forming along the river banks. I saw that people had been walking on them in a couple of places, which is a very dangerous thing to do. I know there are many young people who read this blog so I’ll speak directly to them for a moment: Please stay off the ice on rivers and streams! I was walking down the middle of the frozen Ashuelot River one winter when I was about ten years old and all of the sudden the ice started cracking all around me. I’ll never forget the rifle shot sounds of the cracking ice echoing in my ears as I ran for my life to the river bank. As I clung to a tree I saw the dark cold water come bubbling up through the cracks where I had been walking just a moment before. I was more scared then than I’ve ever been and it took a while before I could stop shaking long enough to peel myself off that tree trunk and scramble up the river bank. You never know how thick the ice that has formed over moving water will be so it’s best to be safe and just stay off it.

Up in the mountains snow cornices can be dangerous but here they don’t seem to do any real harm. A snow cornice is “an overhanging edge of snow on a ridge or the crest of a mountain and along the sides of gullies. They form by wind blowing snow over sharp terrain breaks.”  People walk out on them, not realizing that there is just a thin layer of snow beneath them, and when the cornice suddenly crumbles away they find themselves trapped in an avalanche. A rabbit or squirrel might have trouble with the one in the photo but otherwise I think it’s pretty safe.

The New Hampshire Department of Transportation says that it cost 2 million dollars to clear the snow from this one storm, and that doesn’t include what the individual towns spent. The snowbanks along Pudding Hill Road in Winchester were about waist high. I’d say that was average for this time of year.

So what do you do when the night temperatures fall to ten below zero (F) and only rise to twenty above zero during the day with a gale force wind thrown in for good measure? You stay inside and take photos of the frost feathers growing on your windows, of course. They’re beautiful things to behold.

All in all the blizzard of 2015 was a non-event here. Yes it was windy and cold but it could have been much worse and I’m thankful that it wasn’t an ice storm. Speaking of ice, the woods are full of it. A couple of weeks ago 2 inches of rain fell and puddled up in the low spots. It froze almost immediately and will be there until the ground thaws. Seeing these puddles slowly seep into the soil will be a good sign that spring is happening.

Though there have been photos of blue skies and sunny days in this post most days throughout December and January have looked more like the above photo. Despite the cold, cloudy, snowy weather spring really is right around the corner. Maple sap usually starts flowing in February and the skunk cabbages will be poking up through the snow soon. Male black capped chickadees are already singing their sad fee bee mating calls, the sun is rising higher in the sky, and daylight lasts a little longer each day. Before we know it the Boston Red Sox will start spring training, tree buds will begin to swell, alder catkins will be heavy with golden pollen and winter will be fading into memory. Any time now that itch called spring fever is sure to come upon us.

If we had no winter, the spring would not be so pleasant. ~ Anne Bradstreet

1. Winter Light

 

I called this post winter light because the light has been so unusal over the past week or two. Or maybe it’s just that I’m noticing it more. It is easy and gentle on the eyes and I pay particular attention to it in the afternoon, hoping for any signs of a lengthening day.

 2. Winter Light

This was taken late one afternoon after a snow storm. “Late” afternoon actually means about 4:30 right now.

3. Sunlight on Snowy Trees

This was the view out my back door after a recent snowstorm that quit at about mid day and let the sun come out. With such weak sunshine and no wind the snow stayed on the tress for quite a while.

 4. Ashuelot Sunset 

The Ashuelot River hasn’t frozen over yet but border ice is forming along its banks, growing slowly in towards its middle. I call these ice shelves, and if you aren’t familiar with the lay of the land on the shoreline, they can be dangerous once covered by snow. Twice last year I found myself standing on ice shelves when I thought that I was standing on dry land. Thankfully, they held my weight each time, but I’m being much more careful this year. Walking on frozen rivers is a dangerous game.

 5. River Ice Patterns 

In the shade, patterns could be seen in the ice. The National Oceanic and Atmospheric Administration (NOAA) website tells me that this ice is called columnar ice because of its column shaped grain. This ice is very clear and usually grows in areas with slower flow. Once the river has been covered bank to bank with ice the crystals continue to grow downward, thickening the ice cover.

 6. River Rapids 

On a slightly warmer day I tried to get shots of some interesting waves on the Ashuelot. There’s a rhythm to a river just like with most things in nature, and if you tune in to that rhythm you can get shots of cresting waves every time you click the shutter. If you watch a certain spot and only that spot you find that the river does almost the same thing over and over again, just a few seconds apart.

7. Monadnock from Perkins Pond

I could see from quite a distance that Mount Monadnock had snow on it but I wanted a closer look so I drove to Perkin’s Pond in Troy, which is a favorite viewing place. The pond was completely frozen over and the only sunshine to be had was up on the mountain. The wind often howls down the length of this pond in winter, making this a very cold spot. Still, I’m sure that it was much colder on the summit.

8. Monadnock from Perkins Pond

Snow makes the mountain even more beautiful. It could be ankle deep or shoulder deep. It’s hard to tell from here, and I’m not going to climb it to find out.

 9. Winter Light

In summer I’m usually worn out from traipsing through the woods long before the sun sets, but in the winter the days wear out before I do. When you’re out there with a camera on a cold winter day and everything is going well and you feel that you might be getting some good shots, it’s hard to watch the sun set so early.

10. Sunset on the Waterfall

The setting sun turned the Ashuelot River falls into a golden ribbon one afternoon. I was surprised that they hadn’t frozen.

11. Sunset on the River

The river was also colored gold and had frazil ice pans forming in it. Frazil ice forms in super cooled water and then floats to the surface where it clumps together to make various ice formations .They were a sure sign that the water was frigid, no matter how hard the sun tried to hide it.

Nature is so powerful, so strong. Capturing its essence is not easy – your work becomes a dance with light and the weather. It takes you to a place within yourself. Annie Leibovitz
