Posts Tagged ‘Big Ice’

It was cloudy but finally warm at 38 degrees F. last Sunday so I decided to see how the ice had grown in the deep cut rail trail that ice climbers call the icebox. Since we have had plenty of below zero nights I expected the ice to be big, and I wasn’t disappointed.


Though I’ve seen as many as thirty at a time, on this day there were only two ice climbers here. It was dark in this part of the canyon on such a cloudy day so I had to really increase the ISO on my camera. Sunshine is limited on this part of the trail even on a sunny day because it’s about 50 feet below the surrounding hill that the railroad cut through.


The ice climbers said this was their third time here but they were climbing on a skimpy little ice column that didn’t look like it would support much weight. I pointed out the huge ice column on the other side of the canyon and told them that was where most people climbed, but they stayed where they were and I bid them good luck. You could fit what I know about ice climbing in a thimble anyway.

This massive pile of ice is where most ice climbers climb but on this day you could hear water dripping behind it, and that was odd.


There was a large pool of water at its base as well, and that probably would have given me second thoughts about climbing it. If groundwater was dripping between the ice and the stone of the canyon the whole thing could come tumbling down, and you don’t want to be here when that happens.


But I decided not to think of such things and instead focused on the beauty of the ice. After all, it was why I had come. All of the water that drips from the stone walls of the canyon collects in drainage ditches originally built by the railroad 150 years ago. The water is carried by the ditches out into the woods where it must eventually find its way to a swamp or pond. Meanwhile beautiful patterns form in the ice covered ditches.

Ice can be very beautiful, especially on a warm day when you have time to linger and appreciate it. I often catch myself lost in the photos I’ve taken of it as well, wondering what I might see. I’ve seen birds flying, eyes staring, waves and rivulets caught in mid flow and entire galaxies, all frozen into the ice. I love what it did here; it’s much like a topographic map because if you look closely you see that the ripples formed around peaks, and the peaks are stones in the stream. It’s a beautiful scene, and there are thousands upon thousands of others much like it out there, just waiting to be discovered.


I saw that someone had put up a sign to warn snowmobilers that there were people on the trail. That’s a good idea because the trail curves in the canyon and I’m sure a snowmobiler could be just about on top of the climbers before he sees them, depending on how fast he was moving. I hear people complaining about snowmobilers but I don’t agree, because if it wasn’t for them many of these rail trails would have become impassable long ago. Many snowmobile clubs donate their time and tools and work hard all summer long to keep these trails open and we who use them owe them a real debt of gratitude.


When you come into the canyon you can go north where the ice climbers climb or you can go south where the most colorful ice grows. I usually do both. The walls don’t soar quite as high in this section but the ice comes in many colors and grows as thick as tree trunks.

There was lots of blue ice here this day and I wasn’t surprised because it has been so cold. I’ve heard that blue ice is the hardest and most dense, and its color comes from the way the dense ice reflects light, rather than any imperfections in the water.


Other colors come from the minerals in the groundwater, I believe. Some years you see lots of orange ice like this and in other years you hardly find any. You can see at the base of the column how the snow is stained by the dripping, mineral colored water.


Though I see green when I see this ice my color finding software sees tan. Since I’m colorblind the software gets the call. Whatever the color, this formation was big. This also illustrates why I don’t come here much after the end of February, because when large ice columns like this one release from the stone they often fall like trees, right across the trail. I’d rather not be here when that happens because a person could easily be crushed.

Here is some mineral staining on the stone walls of the canyon. I believe this is what colors the ice but the strange thing is how these colors all but disappear in warmer months. Cold brings out the colors in many things like tree sap, and apparently mineral staining on stone.


It was the texture of this ice column that caught my eye. It was like ten thousand icicles had all frozen together. Quite often you see these ice columns with a smooth, shiny surface but this one was rough.


Here is a better example of how the snow stains at the base of these columns.


Frost flowers bloomed on the ice covering the drainage ditches.


I don’t see these very often so conditions must have to be just right. I’m guessing it has a lot to do with humidity. I see birds flying above Saturn’s rings, and the universe beyond.


This takes the prize as the biggest mass of ice I’ve ever seen off a pond. It’s so big I don’t know how to explain just how big it is. Tons and tons of ice, I’d guess.


Somehow a beech leaf stuck itself to an icicle. I’ve noticed that many beech and oak leaves are falling, and I hope that’s a sign that spring isn’t far away.

A small animal came out of its den for a drink and found the well frozen over. Its tracks made the snow look as if it had been zipped together.


My walk through the canyon ends at the old lineman’s shack, because that’s where the big ice ends. It looks like the old building will make it through another winter, though I don’t know how. It’s the very definition of well built. I picture it full men sitting around a potbellied, coal fired stove, wishing they didn’t have to shovel all the snow out of that canyon. But that chore must have fallen to someone.

Keen observers of the flowers that bloom in spring probably noticed that there weren’t any coltsfoot flowers in my last post. That’s because I hadn’t seen any yet, even though I had been to every place I knew of where they bloom. Except one, I remembered; the deep cut rail trail in Westmoreland that the ice climbers call the “Icebox” has a lot of coltsfoot plants along the trail. So, though I wasn’t sure what I’d find, last Sunday off I went. What I found was where winter has been hiding. As the above photo shows there was still plenty of ice clinging to the man-made canyon walls.

But the ice was rotten and melting quickly. Ice this big can be very dangerous when it falls, so I don’t get near it. I thought it had been warm enough to melt all the ice and snow here but obviously I was wrong.

The opaque gray color is a sure sign of rotten ice. Ice is rotten when the bonds between ice crystals begin to break down because of air and dirt coming between them.

Water was literally pouring from the walls. The groundwater always seeps and drips here but on this day it was running with more force than I’ve ever seen so I think it was meltwater.

And then I saw this fallen ice column. It looked like a boat and was as big as one that would fit 5 people. If this ever fell on a person it would crush them, so I decided to turn back and get out of here.

The view further down the trail didn’t look safe at all with all the ice columns melting in the sunshine, and there was what looked like a pile of ice down there.

That’s what it was; a pile of huge ice chunks all across the trail. I know it’s hard to judge the scale of things in a photo but these ice columns are as big as trees. Actually there is a fallen tree over on the left.

Here’s a shot of some ice climbers taken in February to give new readers an idea of the size of this ice. Some of it is huge.

I think that part of the reason the ice columns fall like they do is because the water in the drainage ditches along the side of the trail erode their bases away, as can be seen in this photo.

Ice isn’t the only thing that falls here. Stones fall from the ledges regularly and I saw at least three fallen trees on this day. I’m reminded each time I come here how dangerous the place can be, but it is also a place where I can see things that I can’t see anywhere else.

One of the things I can’t see anywhere else is the great scented liverwort (Conocephalum conicum.) They grow here by the thousands and I’ve learned to expect them to look a little tattered and worn in spring, because most are covered by ice all winter. By June though they’ll all be a beautiful pea green. Another name for the plant is snakeskin liverwort, for obvious reasons. Its pores and air chambers our outlined on its surface, and that gives it a very reptilian look. In my opinion it is one of the most beautiful of its kind.

I decided to look a little closer at areas with no ice or leaning trees nearby and I’m glad I did because I saw many interesting things, like what I believe is yew leaved pocket moss (Fissidens taxifolius.) This little moss grows in very wet places on the ledges where water drips on it almost constantly. Pocket mosses get their common name from the way the lower lobe of each leaf curls around its stem to form a pocket. This example was a little beat up because it has also most likely been under ice all winter.

Grasses were just coming up in the drainage ditches that follow along each side of the trail. The beech leaf in the foreground will give you an idea of their size.

I saw a large patch of moss on part of a ledge.

It turned out to be Hedwigia ciliata, which is a very common but an uncommonly beautiful moss. It’s also called white tipped moss because its branch tips are often bright white. I usually see it on stones in full sun.

Seedlings were coming up among the mosses. I’m not sure what they are because they had no true leaves yet but I do know that Jack in the pulpit plants grow all along this section of ledge. Many different species of aster also grow on the stone. It reminds me of a radish seedling.

I found that green algae (Trentepohlia aurea) darkens when wet. This hairy alga is orange because of the pigment beta carotene hiding the green chlorophyll. It grows out of direct sunlight on the damp rock walls.

I thought I’d practice my photography skills by trying to get a shot of a stone filled with mica. It isn’t as easy as it sounds because each piece of mica is like a tiny mirror that amplifies the sunlight.

If I could have gotten closer to the ice columns I would have shown you that the ice comes in many colors here. One of the colors is a reddish orange and I believe that it comes from iron leaching from the soil and stone. The above photo is of a spot in the woods where a pool of water was. When the water evaporated it left behind the minerals it carried, in this case probably iron.

I saw this bubbly mass in one of the drainage ditches. I’m not sure but I think it’s some type of algae. It reminds me of the spyrogyra algae I saw a few years ago. That example was on a very wet stone outcrop and this one was in water. I’ve read that it is most abundant in early spring and that the bubbles come from trapped gasses. It isn’t something I see regularly.

I never did find any coltsfoot flowers to show you but there were plenty of other interesting things to see. I also never made it all the way to the old lineman’s shack because of all the fallen ice, but I did see a piece of it; this plank from it was being used as a bridge to cross the drainage ditch. I wish people wouldn’t keep pulling the old shed apart but I don’t suppose anything can be done about it.

By now you might think I’d had enough of ice but there is a special place called the ice box in Westmoreland, just north of Keene, that I couldn’t go long in winter without visiting. I was here a month ago at the end of December but the ice, which often grows as big as tree trunks, hadn’t grown much by then. This is a deep cut through solid rock made by the Cheshire Railroad back in the mid-1800s which has become a popular spot for learning how to ice climb. The New Hampshire branch of the Appalachian Mountain Club holds ice climbing clinics here and on this day there were more climbers here than I had ever seen.

They were young and old and from what I gathered, all skill levels. As I usually do I just wandered through quickly, snapping the shutter now and then. I worry about distracting the beginning climbers so I don’t often speak to anyone or even stand and watch. I’ve asked in the past if my use of a camera bothered them and they’ve always said no, but that wouldn’t make me feel any better if someone fell because they were wondering what I was doing instead of paying attention to what they should have been doing.

What I’d like to ask them is why they don’t ever seem to climb the colored ice. It’s possible that it isn’t as stable as the clear or blue ice. Even though blue ice is the densest they seem to stay on the clear ice when climbing. I’ve read that ice is plastic and actually has quite a lot of give and movement, so maybe that has something to do with it. All of the bags and packs that you see in this photo are what the ice climbers use to pack their ropes out here. They use lots of rope!

These ledges soar up to what I would guess is about 50 feet in places and the ice columns sometimes reach all the way to the top. As I’ve said, they can also grow to the size of large tree trunks and they can be amazing things to see.

Sometimes it isn’t just their size that makes the ice columns amazing. It’s their beauty as well.

I believe that the colors in the ice come from mineral seepage in the groundwater that forms the ice columns, and I believe that simply because I can’t come up with any other plausible explanations. I’ve seen brown ice, green ice, orange ice, blue ice, red ice, and even black ice on these walls, so there must be some kind of mineral soup going on here.

I should say that I know regular readers of this blog have heard me say these things many times but there are new readers coming on board all the time, so I hope you’ll understand why I keep repeating what I say about this and some of other places I visit. This place especially, seems to fascinate those who haven’t ever seen anything like it. It really is quite amazing even to me, and I’ve seen it countless times.

I like the far southern end of the canyon; the end away from the climbers, because there is never anyone here. I think it might be because the ice receives too much sunshine on this end and it melts and fills the drainage ditches along the sides of the trail. I wouldn’t want to climb down an ice column and suddenly find myself standing in two feet of freezing cold water.

In years past I’ve seen huge ice columns colored reddish orange but this year I only saw those colors in the mineral stained stone. You can see in this photo how the groundwater seeps directly out of fractures in the stone.

I saw plenty of tan ice that had a few orangey streaks, but no orange ice.

There was so much ice in some spots you couldn’t see the stone that it hung from.

This photo shows the drainage ditches, which are frozen over at times and clear of ice at other times.

I saw some waves that had been frozen in place. There are small fish in these drainage ditches but they’re very fast so I’ve never been able to get a shot of them.

The ice over the drainage ditches is often thick enough to stand on, but you want to make sure you have high rubber boots on if you do. I’ve plunged through this ice before and found myself almost up to my knees in the cold, wet ditch.

Wherever the water touches the ice columns they melt, and they tell the story of how the water rises and falls in the ditches. We had a recent day with almost 2 inches of rain and there was plenty of evidence of flooding here.

This is one of two places where the water in the ditches rose so high that it washed parts of the railbed away. This was disheartening to see because the same thing happened last winter and the local snowmobile clubs had to put in a lot of time and effort last summer to fix it. They keep these trails open on their own time with their own tools without pay, and that’s why I always remind people to donate a little to their local snowmobile club, if and when they can.

The rushing water scoured away the finer material on the rail bed and exposed the gravel base. Chances are good that this hasn’t been seen in about 150 years, since the railroad workers put it down. It’s interesting to see that most of this stone isn’t made up of pieces of blasted rock from blasting the canyon through the hillside. These stones are more what I’d expect to see on a river or stream bank. So where did they come from? There must be a very big hole somewhere.

I thought I had chosen a good day to come here because it was sunny and approaching 50 degrees. It was a beautiful spring like day but somehow I never gave a thought to the fact that the ice would be melting because of it. But it was, and in places it was melting fast and falling from the walls. This rotten ice was a sure sign that things were changing due to the warmth. Ice is rotten when air bubbles or dirt particles get in between the ice crystals and weaken the bonds between them. It gives the ice a gray, opaque, “sick” look. When you tap on it you hear more of a thud than a good ringing rap.

This wasn’t good and it convinced me that I’d better get out of here, because an ice column had fallen and reached the center of the trail. I always walk in the center of the trail, thinking that if ice ever fell it would never reach me. So much for that theory.

I put a glove on one of the pieces of fallen ice column to give you an idea of how big they were. They were easily big and heavy enough to crush and kill if they ever fell on someone.

All of this freezing and thawing takes its toll on the ledges and stones fall from these walls too. The water gets into the cracks in the stone and expands when it freezes and shatters the stone, as can be seen in this photo. Stones big enough to crush cars have fallen from the walls in the past. I hope I’m not here when the next one comes down.

As I always have I stop and stand in awe of the old lineman’s shack which, even with one wall and half its roof gone still stands. It’s slowly getting worse though and I doubt it will make it through one more winter. I often wonder if they stored shovels in the shack so they could shovel out this canyon when it snowed. I’ve seen photos of train locomotives with big plows on them but where would they plow the snow in a canyon barely as wide as the train was? I think they must have had to shovel it, at least some of it, and I can’t even imagine what back breaking work that must have been.

After one last peek at the ice climbers my time here was done.

After posting the 2 part blog post just before Christmas about searching a new rail trail to find ledges where huge icicles might grow I realized that many readers might have no idea why I would be looking for such things, so I visited one of my favorite rail trails in Westmoreland. This is a deep cut that was blasted through a hillside in the mid-1800s so the Cheshire Railroad could get to Vermont. Groundwater constantly seeps through fissures in the stone and in winter it freezes into huge ice columns as big as tree trunks.

The size of the ice columns can be quite amazing but sometimes the minerals in the groundwater color them and make them even more amazing. The walls of this man made canyon soar up to 50 feet high in places so the ice columns also get very tall. They must be perfect for climbing because the New Hampshire branch of the Appalachian Mountain Club comes here to hold ice climbing clinics.

As luck would have it they were there climbing the ice on this day. Though I didn’t ask I’m assuming that the climber in this photo was relatively new to climbing, because he was on ice that wasn’t very tall. I met climbers here last year who described this kind of climb as a “baby climb.” Just to get used to it, I would think. I try not to be too intrusive or distracting when I see climbers so I don’t ask to many questions for fear of breaking their concentration.

If you are wondering what became of all that blasted stone, in this case the railroad used it to build mighty retaining walls along the sides of the cut where there was hillside soil that had to be held back.

This view is of the opposite end of the canyon from where the ice climbers climb. Though the ice here is nearly as big as on the other end I’ve never seen them climb here, and it wasn’t until this year that I finally figured out why.

At least I think I know why they don’t climb here. The drainage ditches are full of water on this end of the canyon and there is no water in them where the climbers climb. These ditches are almost knee deep in places and I’d hate to climb down an icicle and find my feet in frigid water. This is the section where most of the interesting plants grow though, so when I need to get close to the walls I put on rubber boots and walk in the ditches. I don’t do it often because of the danger of falling ice and stone, but I’ve done it a few times.

These drainage ditches were designed to carry water out of and away from the rail bed, so the water is always flowing like a stream, and the movement keeps the ice columns from growing any further than the surface of the water. It looks like they have been cut off right at the water’s surface all the way down the ditches.

It’s always cold here in winter and it often gets cold enough to freeze the surface of the drainage ditches, and that’s what happened in a few spots on this day. Where they had frozen over long feathers of hoar frost had grown. Without thinking I hold my breath when I’m taking photos of these beautiful, fragile things because all it takes is the warmth of a stray breath to destroy them.

In some places the hoar frost had grown into sharp looking needles. It’s odd to think of frost growing on ice but it happens quite frequently when conditions are right. Humidity seems to play a large part in it.

I’ve learned much from this man made canyon and one of the chief things among them is how cold can change the appearance of stone. It brings out colors in the stone for instance, that aren’t seen when it’s warmer. Colored stains from over a hundred years of seeping, mineral laden groundwater appear as if by magic when it gets cold.

But do the minerals color the ice? I think they do, because I can’t think of any other thing that would. And the color doesn’t come in just green; I’ve also seen orange, blue, brown, and even black ice here. The blue ice is colored by its own density and clarity and by the way it reflects light, but the other colors must come from some foreign material. Brown ice for example, might simply be colored by soil. Orange ice could be colored by the iron in the stone. There’s a lot of it here.

You can see in places how the mineral laden water colors the snow as well as the ice.

Ice isn’t the only reason I come here. There are many unusual plants here that I don’t see anywhere else, and one of them is the green algae called Trentepohlia aurea. Though it’s called green algae a carotenoid pigment in the alga cells called hematochrome or beta-carotene color them orange. It’s the same pigment found in carrots, but in this instance it hides the green chlorophyll in the algae. I couldn’t get close enough to show it but these algae are very hairy. Though I’ve seen orange ice here it wasn’t where the few colonies of algae grow so I doubt they have anything to do with coloring ice. I keep hoping to see the algae producing spores, but so far I haven’t had any luck. In certain parts of the world algae have produced enough spores to color the rain. If you ever hear of red rain falling chances are it’s because of algae spores.

Another plant that I come here to see is the beautiful, reptilian, great scented liverwort (Conocephalum conicum.) This liverwort gets its common name from its clean, fresh scent. It is the only liverwort with this reptilian appearance, so it’s easy to identify. They grow on these ledges by the thousand, constantly watered by splashing groundwater. They like a lot of water but it has to be absolutely clean and unpolluted, so finding this liverwort is a good indicator of very clean water.

White tipped moss (Hedwigia ciliata) also grew in an area where it was constantly splashed by dripping groundwater, and the tiny water droplets made it even more beautiful. One of the first things you notice here in this icy canyon is the sound of dripping water. It seeps and drips year round, winter and summer, through the entire length of the canyon and the sound can be very pleasing or very annoying, depending on your mood. I’ve met people here who described it both ways. There are those who feel that the sound of water intrudes on the peacefulness of a place I suppose, but to me it is like a musical gift from the earth.

Can Ice be beautiful? Oh yes it can, and these windblown icicles looked every bit as beautiful as Lalique crystal to me. For those who may not know, Rene Lalique was a French glass designer who practiced his art in the Art Noveau period (1890-1910.) He is known today for his opaque, matte finish glass, which can look much like these icicles. He was completion for Louis Comfort Tiffany, so if you received a piece of Lalique crystal for Christmas you are very lucky indeed.

Unfortunately, though the opaque finish on Lalique crystal means good things, on ice it does not; especially if you happen to be an ice climber, because ice that looks like this is rotten and unsafe. Ice becomes rotten when water, air bubbles, and/or dirt get in between the grains of ice and cause it to honeycomb and lose its strength. Instead of a sharp ringing crack when it is struck it produces more of a dull thud. The grayish white color and matte finish are a sure sign of rotten ice, and a good sign that you should stay away from it when it’s hanging over your head.

Each winter I come here and stand in awe of the old lineman’s shack, which still stands against the weight of the snow even though it lacks half its roof, a wall and a half, and most of its floor. It has stood here for well over a century and is the very definition of well built. If it wasn’t for people slowly pulling it apart I have no doubt it would still look just as it did when it was built.

The sun was getting lower and a single ray fell on a green icicle. Though it lit up the icicle it had no heat to melt it, and this reminded me how very cold it was here on this day. This canyon usually runs about 10 degrees cooler than it is on the outside and it was 27 degrees F when I came in, so it was no wonder that my toes were cold. I always have to be careful that I don’t wander too far out of myself and get lost in this winter beauty because frostbite is always close by.

With a last look at some beautiful little frost feathers back out into the world I went, hoping that it would be just a bit warmer there. I’ll have to return in a month or two when the icicles should be as big as trees.

In the winter the world gets sharp. Beautiful things happen. ~Peter Fiore

I hope everyone had a wonderful Christmas. Thanks for coming by.

1-trail

We’ve had some cold nights and a little snow over the last week or so and it seems like winter might be here to stay, so I decided to visit the deep cut rail trail in Westmoreland recently. Once the cold settles down inside this man made canyon it’s reluctant to leave, and spectacular ice formations grow here.

2-ice

The ice is fueled by the groundwater that constantly seeps through the bedrock that the railway workers hacked their way through in the mid-1800s, and ice columns as big as tree trunks are commonplace. I’ve seen huge ice columns here many times but I’ve never seen their birth, so that was the object of today’s hike.

3-ice

Ice was forming almost everywhere on the vertical walls of the canyon. It was very cold this day and even in the bright morning sunshine the ice wasn’t melting. That’s the secret of the why the ice grows to such giant proportions here; the temperature seems to stay about 10 degrees cooler in both winter and summer. On a hot July day the natural air conditioning is very welcome, but in December it can be like walking into a freezer so you had better be dressed for it if you plan on spending much time here.

4-ice

The groundwater seems to follow the natural lay of the stone and seeps between the layers winter and summer. The water doesn’t seem to ever stop seeping so when an icicle forms more and more water flows over it, increasing its length and girth drip by drip. There can be enough ice here in February to cover the stone ledges completely in many areas.

5-ice-climber

Unless you’ve seen them the ice formations are hard to imagine, so I’ve used this photo from last February to better illustrate the size of both the ice and the place. Last winter was mild so the ice shown is tame in comparison to previous winters but still, ice climbers came to train. The New Hampshire branch of the Appalachian Mountain Club holds regular ice climbing clinics here and seeing climbers on the ice is fairly common on weekends. I expect that I’ll see a few this winter.

6-waterfall

There is almost always the sound of water dripping here. Usually it comes from the seeping groundwater but in at least one spot water gushes through a rift in the wall with enough force to be called a stream. I wonder if a stream on the hillside above somehow changed course, because I doubt that the railroad engineers would have left it this way.

7-drainage-ditch

All that water has to go somewhere so the railroad built drainage ditches on either side of the railbed to direct it where they wanted it to go. The ditches have kept the railbed dry for over 150 years but I saw that a rockslide further down the trail had dammed up one side and now water is washing away the railbed. With no railroad to maintain these rail trails it’s now up to private groups like snowmobile clubs to do all the work. They do a great job but it they might not be aware of the washout.

8-rock-fall

This is a shot of where the rocks have fallen across the drainage ditch and dammed it up. What isn’t seen in this photo is how all the water in the ditch has been forced into the railbed, washing it away. The rocks are big and I’m sure are very heavy but I would think that two men with crowbars could at least slide them over enough to let the water through.

9-ledges

There are many mosses, liverworts, and other interesting things growing on these walls that I don’t see anywhere else so I put on rubber boots and walk across the drainage ditches to get close to them. I’ve seen large stones that have fallen into the railbed and in the winter falling ice is always a possibility, so I have to be very aware of what’s going on around me. I always look up before I cross a ditch to get to a section of wall to make sure that I’m not going to be standing under overhanging ledge like that seen in this photo. I’ve never seen one fall but fallen stones litter both sides of the trail all down its length.

10-liverworts

For me this is what makes coming here worth any small amount of risk involved; I can get close to so many plants that I’ve never seen before, like the great scented liverworts (Conocephalum conicum) seen here. They are very particular about where they grow, insisting on just the right amount of light, humidity and temperature and they have found the perfect spot here, where they grow in great numbers. Though they are said to be common I never see them anywhere else.

11-liverwort-close

The great scented liverwort is also called the snakeskin liverwort, and with good reason. I love its reptilian skin and its scent, which is so clean and fresh it always makes me wish it came in a spray bottle when I smell it. Each more or less hexagonal leaf cell has a central pore over the top of an air chamber. On the floor of the air chamber are photosynthetic filaments called chloroplasts, and the pores through its skin let in enough light for the chloroplasts to do their work, which is photosynthesis. It’s quite amazing, as is all of life.

12-liverworts

Though the liverworts might seem fragile they are actually very tough as all of the plants that grow here have to be, because they are often completely encased in ice throughout the winter months. From what I’ve seen it doesn’t seem to bother them.

13-ferns

Any thoughts I had about the delicacy of our evergreen ferns went right out the window when I saw them growing here. They too are often covered in ice through the winter, but still green.

14-moss

Mosses also have to be able to withstand the ice. Curiously, though this one was surrounded by ice it was quite dry, as its twisted leaves show. I think it might be tall tornado moss (Tortella tortuosa) which has leaves that twist and contort when it dries out. It grows in the thin soil that forms on boulders and on rock ledges, and likes limestone.

15-algae

One of the strangest things that grow here  is a green algae called Trentepohlia aurea. Though it is called green algae a carotenoid pigment in the alga cells called hematochrome or beta- carotene, which is the same pigment that gives carrots their orange color, hides the green chlorophyll. It’s very hairy and produces spores which, when produced in high enough concentrations, can even color rain. I was just reading about a blood red rain that fell in parts of Spain in 2014. Many worried that it was a bad omen or extraterrestrial in origin, or a plague worthy of the Bible, but it was actually caused by the algae Haematococcus pluvialis. The same thing happened in Texas in 2013, in Sri Lanka in 2012, and in India in 2001, each seemingly caused by different algae. Yellow, green, and black rain has also been reported. It seems that colored rain can happen just about anywhere on earth when conditions are right. The blue in this photo is the sky reflected in ice.

I’ve never seen colored rain falling in this place but I have seen plenty of colored ice, and I think at least some of the ice colors are caused by minerals in the groundwater, like the iron staining shown on the stone in this photo.  The ice here can be blue, green, red, orange, yellow, brown, and even black.

Another example of mineral staining on the stone, this time in a sandy, orangey brown color.

And this photo from last year shows what the minerals can do to the ice. At least that’s my assumption. Neither I nor readers of this blog have been able to come up with any other theories except in the case of blue ice, which can become blue simply because of its own density.

It takes a while to get used to this kind of cold again and by the time I had reached what’s left of the old lineman’s shack I couldn’t feel my toes any longer, so I thought I’d better do a little less lollygagging and more walking, and I trudged back down the trail at a high rate of speed (for me.)

Watching ice melt might not be very exciting but watching it grow is, so I’ll be coming back here often throughout winter.
