One last photo from the recent January thaw when the temperature reached 67 degrees in Concord, our State Capital. It isn’t unheard of but it is quite rare for it to be that warm in January. This photo is from when the thaw had ended and it had started getting colder again. A mist rose from the warm soil and flowed over the landscape like water.

In places what little snow fell after the thaw had been sculpted by the wind. Wind can do strange things to snow. I’ve seen drifts up over my head and curls like ocean waves.

The wind also made ripples on a puddle and then they froze into ice. I’ve seen some amazing things in puddle ice.

I don’t know what it is about grass and snow but the combination pleases me, and I always enjoy seeing them together.

It hasn’t been truly cold this winter but it has gotten down into the single digits at night, and that’s cold enough to turn pine sap blue. I see it in varying shades of blue just about everywhere I go.

When the snow starts to melt it often melts in layers and as the top layers melt away what were mice and vole runs under the snow are exposed. These small animals are active all winter long but are rarely seen. It didn’t look like this one knew exactly where it wanted to go.

Wild turkey tracks are very easy to identify because of their large size. I happened upon a spot where many of them had gathered but since I didn’t see a trail of tracks either into or away from the place I have to assume that they flew in and out of it. Maybe they wanted to catch up on what was happening in the forest, I don’t know.

Sunshine transformed an icicle into a prism for a few moments as I watched.

Snow melts in strange ways. This photo shows how it has melted into a round mound. I’m not sure how or why it would do this. Was it colder in that small, 10 inch spot than the surrounding soil?

I saw a tiny speck move in a cobweb in a building at work so I took my macro camera off my belt and inched it closer and closer until I got the shot of the American house spider you see here. Not surprisingly this tiny, quarter inch spider is called a cobweb spider. The reason it let my camera get so close is because they have poor vision, I’ve read. They can bite but this one didn’t move. I think it was busy eating. They are said to be the most often encountered spider by humans in North America so the next time you see a cobweb this is probably what made it. They can live for a year or more.

Rim lichens are very common in this area but that doesn’t mean they’re any easier to identify. I think this one is a bumpy rim lichen (Lecanora hybocarpa) because of the bumpy rims around the reddish brown fruiting bodies (Apothecia.) They aren’t smooth and round as I’d expect so at first I thought they had simply shriveled from dryness but no, they always look like this. This lichen likes to grow on the bark of hardwood trees in well lighted forests, and that’s exactly where I found this one.

I see lots of drilled holes in stone and many are out in the middle of nowhere, where you wouldn’t expect them to be. Who, I always wonder, would go to all the trouble of drilling a hole in a boulder and then just leave it? An inch and a half diameter hole is not an easy thing to drill in stone.

The smooth sides of this hole tell me it isn’t that old. It might have once been drilled for blasting ledges along the side of a road, but right now it’s filled with pine needles.

If the hole in the stone in the previous photos were from the 1800s it would have a shape like this one, which was made by a star drill. One person would hold the drill bit and another would hit the end of it with a sledge hammer. After each hammer blow the bit was rotated a quarter turn and then struck again. It was a slow process but eventually a hole that could be filled with black powder had been drilled. You filled it with black powder, stuck a fuse in and lit it, and ran as fast as you could go.

Speaking of powder, when I touched this puffball it puffed out a stream of spores that were like talcum. I was careful not to breath any in; there are people out there who seem to think that inhaling certain puffball spores will get them high, but it is never a good thing to do. People who inhale the spores can end up in the hospital due to developing a respiratory disease called Lycoperdonosis. In one severe instance a teenager spent 18 days in a coma, had portions of his lung removed, and suffered severe liver damage.

A thin maze polypore (Daedaleopsis confragosa) wore a cap of snow. This photo doesn’t show much of the maze-like underside of it, but it was there. When fresh the surface is pale gray and turns red when bruised. This fungus causes white rot in trees.

I saw quite a few beautiful blue and purple turkey tail fungi (Trametes versicolor) earlier in the year but now I’m seeing a lot of brown. One of the things I’d like to learn most about nature is what determines this mushroom’s color. It’s like a rainbow, but why? Minerals in the wood would be my first guess but apparently nobody knows for sure.

Among the many things Ötzi the 5000 year old iceman, whose well preserved body was found in the Ötztal Alps in 1991carried were birch polypores (Piptoporus betulinus.) I assumed that he used them to sharpen tools (They are also called razor strops and their ability to hone a steel edge is well known.) but apparently Ötzi carried them for other purposes; scientists have found that Ötzi had several heath issues, among them whipworm, which is an intestinal parasite (Trichuris trichura,) and birch polypores are poisonous to them. The fungus also has antiseptic properties and can be used to heal small wounds, which I’m sure were common 5000 years ago. By the way, polypores always want their spore bearing surface pointed towards the ground, so you can see that these examples grew after this birch had fallen.

I went to visit the skunk cabbages (Symplocarpus foetidus) in their swamp and saw many of the mottled spathes I hoped to see. They weren’t open yet but inside the spathes is the spadix, which carries the flowers. The spadix is a one inch diameter pink or yellow, stalked flower head from which the small flowers emerge. It carries most of the skunk like odor at this point and it is thought by some that it uses the odor to attract flies and other insects that might pollinate it. 

The skunk cabbages grow in a hummocky swamp. When I was a boy I used to jump from hummock to hummock but my hummock jumping days are over, so now I just wear waterproof hiking boots.

How beautiful this life is, and how many wonderful things there are to see. I do hope you’re seeing more than your share of it. It doesn’t take much; the colors in a sunrise, a sculpted patch of snow, the ice on a puddle. All will speak to you if you’re willing to just stop for a moment and look, and listen.

We’re still on the weather roller coaster but it is slowly warming up and the snow is melting, as the melt ring around this pinecone shows. I was happy when I found this because it answered a question that I’ve had for a long time: why do melt rings form around tree trunks? As the pinecone shows it has to be the sun warming it up, and as the pinecone releases that warmth the snow around it melts. Or maybe it’s simply heat radiating from the pinecone during the day when the sun is shining. The dark cone would absorb more sunlight than the white snow would.

Here is a melt ring just getting started around this tree. A study done by Emeritus Professor of Botany Lawrence J. Winship of Hampshire College, where he used an infrared thermometer to measure heat radiated by tree trunks, found that the sunny side of a red oak was 54 degrees F. while the shaded side was just 29 degrees F. And the ground temperature was also 29 degrees, which means it was frozen. This shows that trees really absorb a lot of heat from the sun and it must be that when the heat is radiated back into the surroundings it melts the snow. The professor found that the same was true on fence posts and stumps so the subject being alive had nothing to do with it, even though a living tree should have much more heat absorbing water in it. In my mind, the pinecone in the previous photo answers the question of melt rings.

But I didn’t have long to wonder about melt rings on trees because on Monday March 4th we got about 6 inches of new snow. This shows part of my drive to work that day.

I pass this scene almost every day so I can see if the ice is melting. It was and then it wasn’t. Winter can be very beautiful but the pull of spring fever can be terribly strong. By this time of year almost everybody but is ready for spring and waiting impatiently.

It’s hard these days to follow a trail that hasn’t been broken. It never used to be but things change. I’ve never been a real fan of snowshoes so I used to just trudge through it, even if it was up to my knees, but going any real distance through snow much deeper than your knees is a struggle at any age and in any condition, and these days I avoid it.

But as I said it can be beautiful enough to stop you in your tracks. Every season has its own beauty, as this early morning view of Half Moon Pond in Hancock shows.

No matter what the sun always appears again and it was very beautiful on this eastern hemlock tree, I thought. I think algae colored its trunk and the sun came along and lit it up. You can walk just about anywhere in nature and find beauty like this any day of the week, and if that isn’t a gift I don’t know what is.

It’s amazing how a little sunlight can transform the simple into something beautiful, as it did with these deer tongue grass leaves.

I don’t think I’ve ever shown icicles hanging from the eaves on this blog before, but that might be because they are so common. You see them on just about every structure in winter.

I love the way icicles sparkle with color in the sun like prisms. This shot doesn’t quite catch it but there was a lot more color in them.

One cold morning frost flowers bloomed on the ice of mud puddles. They form when the frost point in the air is reached and water vapor condenses into ice. They are a form of hoarfrost, so delicate that a touch of a finger or a warm breath will destroy them. In my experience it has to be very cold for them to form, but there also has to be plenty of water vapor in the air. That’s why hoarfrost is often found near streams and ponds.

Mount Monadnock is an old friend, there in my earliest memories, and it is always at its most beautiful when snow frosts its peak. I would guess the snow must be at least 5 feet deep near the summit. I was up there with a friend of mine on April 19th one year and it was about chest deep in places. We had to climb over it and kind of swim through it rather than trying to break a trail through it. The air was warm and the snow was melting, and the fog generated by the cold snow and warm air mixing together was so dense you could barely see your hand at the end of an outstretched arm. I don’t think I’ve ever been as wet as I was that day.

Tramp art was done by chipping and whittling a piece of wood with a pocket knife. Often pieces of wood from cigar boxes and orange crates were turned into picture frames and other household items which were sold for meager amounts of money. That’s what this piece of branch reminded me of when I saw it but the hand of man played no part in this art; it was made entirely by engraver beetles and was very beautiful, I thought. I wish I had kept it and brought it home but then if I had the next hiker to come along couldn’t have marveled at its insect carved hieroglyphics as I did.

I’ve taken many photos of frullania liverworts throughout the winter but never posted any of them because it’s a tough plant to get a good shot of. It’s a leafy liverwort but each leaf is smaller than a house fly so it isn’t an easy subject. There are about 800 species of frullania liverworts and many grow as epiphytes on the bark of trees where the humidity is high. Epiphytic plants take nothing from the host plants they grow on; instead they simply perch there like birds. Mosses and lichens are also epiphytes.

The liverwort’s tiny leaves are strung together like beads, and change from green to deep purple in cold weather. Frullania liverworts can cause a rash called woodcutter’s eczema in some people. It’s an annoying, itchy rash but doesn’t cause any real harm, and it disappears in a week or two if you stop handling logs with liverworts on them.

This post started with winter but it will end with spring, and that illustrates how quickly one season can change into another here in the northeast. Sometimes it’s as if someone flipped a switch, and it’s what inspired Mark Twain’s “If you don’t like the weather in New England just wait a few minutes” quote. Here our earliest flowering plant, the skunk cabbage (Symplocarpus foetidus,) has finally shown its mottled yellow and maroon flower spathes.

Some are yellow with maroon spots and some are maroon with yellow spots. It’s good to finally see them no matter what colors they choose to wear. The spathes shown here appear first and multiple flowers grow inside the spathe on a spadix. Soon the spathes will begin to open so insects can enter and pollinate the tiny flowers, and so a photographer or two might get some photos of them.

Sap collecting has begun but you’d hardly know it these days. When I was a boy it seemed like every yard had trees with sap buckets hanging from them in spring but I had to search long and hard to find just a few this year, and I fear family sap gathering a dying art. Nobody knows when or where sap gathering started but most agree that it was learned from Native Americans. They used to cut a V notch into the bark of a tree and then put a wedge at the bottom of the cut. The sap would drip from the wedge into buckets made of bark or woven reeds, or sometimes into wooden bowls. They would then boil it down until it thickened and became syrup.

This Library of Congress photo from the early 1900s shows a Native American woman tapping trees and gathering the sap in what appears to be bark buckets, which it looks like she is making. Birch bark buckets are entirely plausible since they made canoes from the same bark. Sticky pine or spruce sap on the seams made their canoes leak proof. Since it takes about 40 gallons of sap to make one gallon of syrup sap gathering was a lot of work, and it was almost always done by the women of the tribe. There are many legends about how Natives discovered the process but nobody really knows for sure. Red and silver maples as well as sugar maples were tapped. So were hickory, box elder and birch, though in those trees the sap was less sweet.

I’ve read about mallards migrating and some articles say they do and others say they don’t, so I’m not sure if this photo is a true sign of spring but I saw these two dancing on the ice at a local swamp, most likely hoping for it to hurry up and melt like the rest of us. I thought it was a pretty, spring like scene.

1. Abandoned Road

We had another snow storm recently and though we didn’t get that much snow it did have to be plowed. The worst part of this storm was the long stretch of freezing drizzle that came after the snow. It glazed the top of the snow in a thick coating of very slippery ice, so I had my Yaktrax on for this walk up the old abandoned road that follows Beaver Brook in Keene.

2. Icy Snow

This shot will give you an idea of just how icy it was. The crust was thick enough for me to walk on without breaking through, which is unusual. When I was a boy I went sledding in this kind of snow just once. The runners of the sled broke through the crust and it stopped dead, but I didn’t. I flew off the front of the sled into the sharp crusty snow and got a nasty gash on my chin that I didn’t think would ever stop bleeding. I’ve been wary of this kind of snow ever since. It can be tricky to walk on.

3. Cloud Blocked Sun

There was blue sky to be seen but also enough clouds to blot out the sun for most of the time.

4. Snowy Woods

Enough snow came with this second storm to fully cover the forest floor.

5. Beaver Brook

I like seeing the ice formations in winter but Beaver Brook had very little ice on it. After the warmest December ever recorded our January temperatures have also been above average so far, but the month is young. As we found out during the last two winters, it can get awfully cold in a hurry.

6. Fern

Our evergreen ferns look dainty and fragile but they can stand up to some fierce weather. I didn’t look closely but I think that this one was an intermediate wood fern (Dryopteris intermedia) because of the shorter leaflets (Pinnae) at the base of its stem (Stipe) and the scales along the lower part of its stem.

7. Fern

This one grew out of a log as if it was spring. I think it might be another younger intermediate wood fern (Dryopteris intermedia.)

8. Smokey Eye Boulder Lichen

This is the place where I began to pay attention to the beautiful smoky eye boulder lichens (Porpidia albocaerulescens) that grow on the ledges. They taught me that lichens can be pruinose, which means they can have a waxy coating that reflects light much like the whitish bloom on blueberries. These (sometimes) blue disks are called apothecia and are where the lichen’s spores are produced. The wax coating makes them appear blue in the right light and their black border makes them really stand out from the body (Thallus) of the lichen. In certain light the apothecia can also appear more gray than blue.

9. Yellow Crust Fungus on Hemlock

The base of this hemlock (Tsuga canadensis) was covered in a yellow crust fungus. I think it might have been the conifer parchment fungus (Stereum sanguinolentum,) which is also called the bleeding parchment because of the red colored juice they exude when they’re scratched or injured. This example was very thin and dry and probably wouldn’t have reacted if I had scratched it. Conifer parchment fungus can cause brown heart rot, which is a reddish brown discoloration in the wood of conifers.

10. Yellow Birch Bark-2

The thin papery bark on this yellow birch (Betula alleghaniensis) had peeled back to show its lenticels. Lenticels are corky pores that allow gases like oxygen to reach the living cells of the bark. Without enough oxygen, bark can die. Yellow birch likes rich, moist, and cool soils so we don’t see them as often as white birch. In this place it grows well on the shaded side of the road, but there isn’t a single example found on the sunny side.

11. Icicles

Winter has teeth and it will bite the unprepared. I met someone here who wore only sneakers and he said “I don’t know what I was thinking when I put sneakers on to come up here!” He was having a hard time of it and I would imagine that his feet were soaking wet and very cold by the time he made it out of here.

12. Crustose Lichen

Every nature walk seems to come with its own bit of mystery and this one was no different. I’ve never seen this lichen before and don’t know its name. I know that it’s a gray crustose lichen, but that’s about all. I don’t know what the dark outlines signify either but they make it look like some kind of ancient petroglyph.

13. Beaver Brook

While I was following the brook and trying to get a shot of a placid pool I didn’t notice the blue of the sky that the rushing water reflected, nor did I see the yellow sulfur dust lichen (Chrysothrix chlorina) on the stone. I’m not surprised; the camera often sees things that I don’t.

14. Peace Pipe

Someone turned the old drain pipe into a peace pipe. Being able to see this pipe shows how much of the road Beaver Brook has eaten away over the years.

15. Beaver Brook Falls

I made it all the way to Beaver Brook Falls but the path down to the brook was too icy for me, so I took this shot from the road, where the view is marred by brush. The falls were roaring as usual and showed no sign of freezing. I was surprised when I came here last year and saw the falls  frozen into a huge lump of ice. The ice muffled almost all sound and it was the one and only time that I’ve ever heard so little sound in this place. When you expect the roar of rushing water silence can seem amazing.

16. Sunshine

Typically, the sun came out from behind the clouds just as I was leaving, but I don’t mind an occasional cloudy day. Last summer was made up of an almost endless string of sunny, cloudless skies and I learned then what the term “too much of a good thing” really meant.

By walking in a snowy forest you can really forget about this world, and every time you forget about this world you leave this world, and every time you leave this world you gain a very special wisdom that does not exist in this world. ~Mehmet Murat ildan

1. Beech Leaf

I saw a beech leaf with a bright white crust that I can’t identify on it. It was thin enough to seem part of the leaf and I’ve never seen anything like it.

2. Blue Turkey Tails

After two years of seeing hardly any turkey tail fungi (Trametes versicolor) this year I’m seeing them everywhere, and in some beautiful colors too. Over the last two years virtually every one I’ve seen has been in shades of brown but this year blue and purple seem to be the most abundant colors. This bracket fungus gets its common name from the way it resembles a turkey’s tail. According to the American Cancer Society there is some scientific evidence that substances derived from turkey tail fungi may be useful against cancer.

3. Deep Blue Turkey Tails

Some of the turkey tails appearing this year have been wearing a deep beautiful blue that I’ve never seen them wear before. Their fuzzy surface makes them look as if they’ve been cut from blue velvet cloth.

4. Blue and Orange Turkey Tails

These examples in blue, orange, tan, brown and even touches of salmon pink have to be the most colorful and beautiful examples of turkey tails that I’ve seen.  Who can say that there isn’t any color to be seen at this time of year?

5. Polypore Pores

Though a polypore will rarely have gills most, including turkey tails, have pores like those seen in the above photo. These pores form tubes and their sides are covered with a spore forming surface called the hymenium. The tubes protect developing spores and help increase the spore producing surface. The size and shape of pores can vary a lot between species and some are small enough so they can’t be seen with the naked eye. Those shown in the photo were challenging but after several tries I was able to get a passable photo of them.

6. Polypore Pores

Not all polypore pores look alike though. Some appear stretched and elongated and maze like as the examples in this photo show.

7. Polypore

The maze like surface shown in the previous photo belongs to another polypore called the thin maze flat polypore (Daedaleopsis confragosa.) Though its upper surface is zoned like a turkey tail the zones tend to be tan to brown to cream, rather than brightly colored like a turkey tail.  Michael Kuo of Mushroom Expert. com says that this mushroom’s appearance is highly variable, with pores sometimes appearing elongated and sometimes more round. The lower pore bearing surface will also sometimes bruise a reddish color and other times won’t.  Once you get used to seeing and identifying turkey tails though, you’ll never confuse this one for one of them.

8. Velvet Shanks

Velvet shank mushrooms (Flammulina velutipes) are considered a winter mushroom and are very cold hardy. They grow on standing trees and cause white rot and I find them quite often growing on American elm (Ulmus americana) as they were in this photo, sometimes dusted with snow. The orange caps of these mushrooms often shade to brown in the center. The stem is covered in fine downy hairs and that’s where this mushroom’s common name comes from. When the temperature drops below freezing on a winter day it’s a real pleasure to see them.

9. Orange Jelly

This jelly fungus (Dacrymyces palmatus) I found growing on an old hemlock stump was the deepest orange color of any I’ve seen. Jelly fungi can be yellow, orange, white, pink, red, or black and grow on deciduous or evergreen trees. They can absorb up to 60 times their weight in water and when dry are little more than colored scales on wood. I found one recently that had fallen from a tree to the forest floor where it sat on a leaf. I tried to pick it up but it was so slippery that I couldn’t pinch it between my fingers to get a grip on it. It was just like trying to pick up a piece of gelatin, and I quickly gave up the idea of ever holding it in my hand.

10. Zig Zag Scar

A few years ago I found this old hemlock with a zig zag scar and I happened to walk by it again recently. None of us could really explain the scar, which comes right out of the soil and runs about three feet up the trunk. Some thought it might have been caused by lightning and I suppose it’s possible, but lightning strikes usually cause much more damage to a tree than this. I haven’t seen anything similar in Michael Wojtech’s excellent book Bark either.

11. Zig Zag Scars

A while ago I found the two zig zag scars in the center of this photo on another hemlock and I wonder if the scar in the previous photo might not be just a natural occurrence. It’s a mystery.

12. Icicles

If you didn’t see an occasional icicle you wouldn’t guess that it was December here in New Hampshire. The temperatures have soared above the average almost every day through November and now December. As of this writing we’re 8.5 degrees above average for the month and if we keep going like we have we might break the record for warmest December going all the way back to 1881.

13. Ice Needles

I did find some ice needles in a wet, shaded spot on an old dirt road. When the air temperature is below 32 degrees Fahrenheit right at the soil surface and the soil and groundwater remain thawed, hydrostatic pressure can force the groundwater, sometimes super cooled, out of the soil where it freezes instantly into a “needle.” As more water is forced out of the soil the process is repeated over and over, and each needle grows in length because of more water freezing at its base. From what I’ve seen the needles almost always freeze together and form ribbons like those seen in the above photo.

14. Puddle Ice

The paper thin white puddle ice that makes that strange tinkling sound when it’s broken always takes me back to my boyhood. Seeing this ice on puddles after a long winter meant that spring was here and though nights still got cold and icy, the days were warm and muddy. Before long school would let out for the summer and I’d be free to roam the woods and explore the banks of the Ashuelot River once again. My father would have warmed the seat of my pants for me more than once if he’d known all the foolhardy things I used to get up to back then. He was forever telling me to stay away from the river but for me it was like a magnet, and it taught me so much.

15. Geese on the River

Just like the turkey tails we saw previously the Canada geese have returned after a two year absence. This is a favorite spot of theirs on the Ashuelot River but two years ago they just stopped coming for no apparent reason. I wonder if it was just a coincidence that they and the turkey tails disappeared during two of the worst winters we’ve seen in recent memory, or if they somehow knew that those winters would be severe. I think I lean toward them sensing that those winters would be extreme because I doubt that very much in nature happens merely by coincidence. Anyhow, it’s nice to see the geese and the turkey tails back again; they were missed.

16. Riverside

I’m not sure what drives people to stack rocks but I suppose it’s something inside some of us that is almost as old as the rocks themselves. The urge was strong enough to make whoever stacked these rocks go for a walk in what I expect were the frigid waters of the Ashuelot River. Personally I’ve never had the urge to stack rocks but I suppose nature tugs at each of us in different ways. In my opinion they detract from rather than add to the beauty that is found in nature, but I’m sure not everyone feels that way. In this case the river will wash them away in no time at all anyway.
