Posts Tagged ‘Spirogyra Algae’

I hope you’re in a nice warm place while reading this because this post is full of ice like that in the photo above, and you might feel a little chilly by the time you’ve reached the end.

Last Sunday, about a month since my last visit, I decided to visit the deep cut rail trail up in Westmoreland where the “big ice” grows each winter. The walls of the manmade canyon are 50 feet high in places and groundwater running through the stone creates ice columns as big as tree trunks. I wanted to see how much the ice had grown in a month.

It had grown quite a lot; enough to climb, in fact and by chance the Appalachian Mountain Club were training here today. They come here as soon as the ice is safe to train people in ice climbing. On this day the 25 degree temperature and 10 mile per hour wind made this place feel like an icebox, and that’s exactly what the climbers call it.

I was here for ice too; not to climb but to photograph, and I saw plenty.

There was an entire canyon full of it.

Some of the ice is colored various colors, I believe according to the minerals that happen to be in the groundwater.

There are plenty of mineral stains to be seen on the stones where groundwater has seeped out of cracks and it makes sense that mineral rich water would color the ice.

This slab of ice is huge and if it ever lets go of the rock it grows on I hope I’m nowhere near it.

I speak about “rotten ice” a lot when I come here so I thought I’d show you the difference between good, solid ice like that in the above photo and the rotten ice in the following photo. This ice is clear and very hard and will ring sharply if you tap on it. It has very few air bubbles and other impurities trapped inside it.

Rotten ice on the other hand is opaque, weak and full of impurities. 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. When you tap on ice that looks like this you hear a dull thud. The grayish white color and matte finish are a sure sign that you should stay away from it when it’s hanging over your head like it can do here.  

Falling ice is a real danger here; most of these pieces were big enough to have killed someone. This doesn’t usually happen until the weather warms in March though, so I was surprised to see it.

Then there are the falling stones. These fell very recently because they were on the ice of the frozen drainage channel. This always concerns me because I walk in or over the drainage channels to get to the canyon walls. That’s where interesting mosses and liverworts grow. If I had been hit by any one of those stones it would have been all over.

But speaking of the drainage channels, the ice growing on them was beautiful.

The opening photo of this post also shows ice that formed on the drainage channel, just like that in the above shot.

Here was something I’ve never seen; an icicle fell and stabbed through the ice on the drainage channel, and then froze standing up.

Last year’s leaves were trapped under the ice in places.

In other places the drainage channel hadn’t frozen at all. Here the sun was reflected in the water of the channel. I thought the colors were very beautiful. Like molten sunshine.

This spirogyra algae dripping off the stones was something I’ve seen but have never seen here. Spirogyra has common names that include water silk and mermaid’s tresses. It is described as a “filamentous charophyte green algae of the order Zygnematales.” I’ve read that they grow in nutrient rich places. They’re always interesting and I wanted to take a closer look but I didn’t have my rubber boots on so I couldn’t walk through the drainage channel.

Here is some spirogyra algae that I found last year. The strange thing that looks like a vacuum cleaner hose is a chloroplast, and its spiral growth habit is what gives these algae their name. There are more than 400 species of Spirogyra in the world, almost always found in fresh water situations. According to what I’ve read, when used medicinally spirogyra are known as an important source of “natural bioactive compounds for antibiotic, antiviral, antioxidant, anti-inflammatory, and cytotoxic purposes.” As I said; they’re always interesting.

NOTE: A botanist friend has written in to say that chloroplasts are microscopic so the hose like thing is not one of those, but neither one of us can figure out exactly what it is. It’s a very strange thing to be seen under algae, that’s for sure. I wish we had studied algae in the botany classes that I had!

The orange red color in this shot is iron oxide, washed from the soil by groundwater. I thought the colors in this scene were amazing; otherworldly and beautiful. There was much beauty to be seen here on this day and it reminded me why I come here again and again.

As I always do I stopped at what is left of the old lineman’s shack. It was easy to imagine a group of workers huddled around an old potbellied stove in there on a day like this, but it would have had walls and a roof then. It was very well built and simply refuses to fall. They actually used railroad ties for the sills.

Here is a look at the inside of the shack. It’s too bad people feel the need to tear things apart, but it has probably been abandoned for close to 50 years now, since the Boston and Maine Railroad stopped running in the 1970s.

If you aren’t cold yet you must be a real trooper, but I thought I’d end with a warm shot of sunshine and blue sky just in case. With the wind chill the temperature was about 10 degrees F, and I was thankful that my cameras hadn’t stopped working. I was also thankful to be back in a warm car again even though I discovered that wearing a cloth mask is a good way to keep your face warm. Hopefully spring isn’t too far off.

It’s getting cold. Some of you will put on jackets from the last season. Check your pockets. You might  well find a forgotten, unfulfilled wish.

We’ve seen cold, rain, snow and mostly cloudy days lately so last Saturday when it was wall to wall sunshine and 65 degrees, it seemed like a great gift. Since it was near time for wild columbines to bloom I set off along the old rail trail up in Westmoreland to the ledges where they grow. I saw all kinds of beautiful and interesting things there and it was hard to leave.

The first thing I saw was a small patch of coltsfoot (Tussilago farfara.) It’s hard to believe that it’s almost time to say goodbye to this cheery little spring ephemeral but I’m seeing white in almost all the flowers I look at these days, and white is a good sign that they’re setting seed.

Red elderberry (Sambucus racemosa) grows beside the trail and it was all ready to bloom. By now it probably has.

Maple buds were breaking; the first I’ve seen this year. New maple leaves are often bright red as these were.

The velvety buds of striped maple (Acer pensylvanicum) were seen all along the trail. Sometimes they can be pink, orange, or a combination of the two like this one was.

When I looked at the other side of the bud I saw that it was breaking. The next time I come out here I should see leaves.

There is a lot of groundwater very close to the surface in Westmoreland and it runs from the cracks in the stone. That’s one reason such a variety of plants and mosses grow here.

Algae dripped from the cracks in the stone, or maybe they were washed down the face of the stone by the never ending drip of groundwater. I’ve read that they grow in nutrient rich places. They’re always interesting so I wanted to take a closer look.

The algae were spirogyra, with common names that include water silk and mermaid’s tresses. It is described as a “filamentous charophyte green algae of the order Zygnematales.” The strange thing that looks like a vacuum cleaner hose is a chloroplast, and its spiral growth habit is what gives these algae their name. There are more than 400 species of Spirogyra in the world, almost always found in fresh water situations. I see it on wet stone fairly regularly. According to what I’ve read, when used medicinally spirogyra are known as an important source of “natural bioactive compounds for antibiotic, antiviral, antioxidant, anti-inflammatory, and cytotoxic purposes.”

That little black square up ahead is where we’re going, but it won’t be black when we get there.

Our wild cherries should be blooming soon, and the birds will be very happy about the abundance of fruit that will follow.

This is near the area where I saw a huge black bear last year at this time. Since there are high stone ledges and a southern exposure it would stay quite warm here in the winter I would think, and that tells me that it would be a perfect spot for a bear to live. The one I saw here certainly looked like it had been living the high life.

There is even a cave here, way up high in the cliff wall, and it’s plenty big enough for a bear. Thankfully the bear was elsewhere on this day. I carried a can of bear spray but I was very happy that I didn’t have to use it. I’ve been within touching distance of a few wild animals and last year’s encounter is the closest I ever want to be to a bear, but so far they seem to have sensed that I mean them no harm and we’ve gone our separate ways.

This is that black spot we saw in a previous photo and these are the ledges I was interested in visiting. They’re right alongside the trail and all kinds of plants grow here. I believe it’s because the stone is full of lime and the soil is much less acidic than in most other places I visit. Most Southern New Hampshire soil is quite acidic but you do find occasional “sweet spots” like this one.

Jewelweed (Impatiens capensis) seedlings grew at the base of the ledges. I see lots of these in the spring and I’ll see lots of their orange flowers later on.

I come out here to see wild columbines (Aquilegia canadensis) and there are plenty of them growing on the ledges. On this day most had buds but I didn’t see a single flower, so that means another trip out here this weekend. The spring shades of green are always electric here.

Here was a flower bud. Some buds looked to be close to opening but we aren’t getting a lot of sun lately so I wonder if they’ll be fully opened this weekend.

The spring shoots of smooth Solomon’s seal (Polygonatum biflorum) absolutely glowed, and it looked like someone had dipped a paintbrush in pure light and painted them there on the ledges. How beautiful they were. Native Americans and early colonists ate these shoots the way we would eat asparagus and they used the plant’s starchy roots in soups and stews, and dried them to make flour for bread. The Chippewa tribe sprinkled the dry roots on hot stones and inhaled the smoke to cure headaches.

Though herb Robert (Geranium robertianum) blooms from spring through October I didn’t see any flowers on this day, even though there were many plants growing at the base of the ledges. Native Americans used this plant medicinally for healing wounds, herpes and skin eruptions. The plant’s common name comes from a French monk who lived in 1000 AD, and who is said to have cured many people by using it. For that reason it is also called Saint Robert’s Herb.

There’s a nice clump of purple trillium (Trillium erectum) here at the base of the ledges and it had two or three blossoms on it this year. Last year there was only one.

One of the flowers looked a little torn but it was still beautiful.

Something I’ve been searching for for a long time are the small blue spring shoots of blue cohosh (Caulophyllum thalictroides) and this year I found them but I was about a week late and they had grown to about 6 inches high. They had also lost that vivid purplish blue color that they have when they have just come out of the ground. But now I know that next year I need to come a week or so earlier, and I’ll be here.

You can see a little bit of blue on this shoot but I’d bet by this posting the plant has already turned green. The green is kind of a light blueish green. Cohosh means “rough” when translated from Native American Algonquin language, and refers to the knobby root. A tincture of the root was said to start childbirth but science has shown the entire plant to be toxic. It’s shadow over on the right makes me think of an alien creature.

Treasures are hidden away in quiet places. They speak in soft tones and often become silenced as we approach. They don’t beg to be found, but embrace us if we do happen to find them. They are the product of completely ordinary circumstances unfolding in wonderfully extraordinary ways. They are found hidden in the nooks and crannies of our existence; all around us if we quit allowing our attention to be captivated by that which is noisy and listen for that which is quiet and still.
