Posts Tagged ‘box culvert’

John Burroughs said “To find new things, take the path you took yesterday,” and that was to prove very true last Sunday. I followed a rail trail in Swanzey that I’ve followed more times than I can count but saw many things that I’ve never seen here before.

Male American Hazelnut catkins swayed lazily in the slight breeze. They had lengthened to three times their winter length and were still heavy with pollen.

The tiny female flowers were waiting for a good dose of that pollen so they could become the hazelnuts that so many birds and animals eat.

There is a nice little box culvert out here that I always like to stop and see. There was quite a lot of water in the stream it carries safely under the railbed on this day. It’s amazing to think these culverts are still keeping railbeds from washing away 150 years after they were built, and without any real maintenance.

The stream rushes off to the Ashuelot River, which is out there in the distance.

The first thing I saw that I had never seen here were trout lily leaves (Erythronium americanum). I didn’t see any flowers but I found the leaves growing all along the trail, and I couldn’t believe that I hadn’t ever seen them.

You can get a glimpse of the Ashuelot River here and there along the trail. This was where I was to get another surprise. I saw something swimming quickly toward me from those fallen trees you see in this photo. I thought it was ducks but I couldn’t see anything except ripples.

And then up popped a muskrat. At least I’m fairly certain it was a muskrat. Though it never showed me its tail it was much smaller than a beaver and nowhere near as skittish. It saw me up on the embankment but still just sat and fed on what looked like grasses. It probably knew I was far enough away; this photo isn’t very good because my camera was at the limit of its zoom capability. At least you can see the critter, and that matters more to me than a technically perfect shot.

I knew that apple moss (Bartramia pomiformis) grew here and I was able to find it. Its reproduction begins in the late fall and immature spore capsules (sporophytes) appear by late winter. When the warm rains of spring arrive the straight, toothpick like sporophytes swell at their tips and form tiny globes that always look like pearls to me, but someone thought they looked like apples and the name stuck.

Beech buds (Fagus grandifolia) are beginning to lose their straightness and that means the beautiful new spring leaves will be appearing before long. Beech bud break begins when the normally straight buds start to curl, as in the above photo. The curling is caused by the cells on the sunny side of the bud growing faster than those on the shaded side. This creates a tension that curls the bud and eventually causes the bud scales to pull apart so the new leaves can emerge. The buds literally “break” and at the bud’s location on the tree branch an entire year’s new leaves and stems will often grow from a single bud.

New maple leaves were everywhere but every one I saw was green. That was unusual because young maple leaves are often red for a while.  

Raspberry plants were also showing their new leaves but blackberry buds had barely broken.

I saw native cherries in all stages of growth. Cherries usually leaf out and blossom quite early.

Some of the willows along the trail had thrown in the towel and were finished for this year.

This is what the flower buds of a shadbush (Amelanchier canadensis) look like. After shadbushes come the cherries, closely followed by the crab apples and apples, and then the peaches and plums. Shadbushes bloom earlier than the other shrubs and trees but are often still in bloom when the others bloom. The flowers appear before the leaves, unlike apples and some native cherries. Small, reddish purple to purple, apple shaped fruits follow in June. The fruit is a berry similar in size to a blueberry and has from 5-10 seeds. They taste best when they are more purple than red. Shadbush flowers are pretty but their fragrance isn’t very appealing. I can’t remember ever seeing them bloom along this trail but there they were.

Forsythia has escaped someone’s garden and was blooming happily beside the trail. Another surprise.

Trailing arbutus (Epigaea repens) is also called mayflower because that’s often when its small white to pink, very fragrant flowers appear, but here they were blooming beside the trail. This is another plant I can’t remember ever seeing out here before. Trailing arbutus was once collected into near oblivion but these days it can be found at many nurseries so there is no longer any reason to dig it up. Since it’s very fussy unless it’s given the right amount of light, water, nutrients and soil type it won’t grow except where it chooses to anyway. The reason it was collected so much was because its small pink to white, very fragrant flowers were used in nosegays.

I reached the trestle and found that someone, most likely a snowmobile club, had overlaid the flooring, which was starting to rot out. This was a another welcome surprise because that little square that juts out to the right was a hole right through the boards. It’s quite a drop down to the river.

This trestle is the last one I know of with its tell tales still in place. These are pencil size pieces of soft wire that hang down low enough to hit the head of anyone standing on top of a freight car. They would warn the person, or “tell the tale” of an upcoming trestle. I can walk from the trestle to this one in under a minute, so whoever was on top of the train wouldn’t have had much time to duck before they’d hit the trestle, and that would have been too bad. Tell tales used to hang on each end of every trestle in the area, but this is the last one I know of.

The river has come up some since the recent snowfall and a few rain showers. I was surprised I didn’t see any kayakers. They like to paddle the river in spring when the water is high because in that way they can float over all the submerged fallen trees.

It still has to gain more run off before it reaches its average height, by the looks. We’re still in a drought according to the weather people.

I was surprised to find a small colony of bloodroot plants (Sanguinaria canadensis) as I was leaving. This is another plant I’ve never seen growing here, so this day was packed full of surprises.

Bloodroot flowers don’t usually open on cloudy days and I couldn’t tell if this one was opening or closing, but I was happy to get at least a glimpse of its beautiful inside. These flowers aren’t with us long.

On Easter Sunday I thought, since it was such a beautiful day, that I’d head up to Westmoreland to see if I could find some of the beautiful blue spring shoots of the blue cohosh plant that grows here. I found them last year but I was about two weeks late because they had already started turning green.

Right off I saw a red elderberry (Sambucus racemosa) with flower buds. This was a surprise since the others I’ve seen haven’t even broken bud yet. Had I been earlier the finger like leaves would have been deep purple. The purple flower buds will quickly turn green before blooming into a head of small, white flowers, and if pollinated they will become bright red berries.

I saw lots of railroad artifacts here on this day, including this old signal base.

I was shocked to find the buds of striped maples (Acer pensylvanicum) showing. I think this is the earliest I’ve seen this happen. As the buds grow they will become beautifully colored in pink and orange.

There are lots of beech trees up here but the buds didn’t show any sign of swelling or lengthening. They will become one of the most beautiful things found in a spring forest when the buds break and the leaves start to show. It won’t be long!

Last year’s beech leaves have turned white and become thinner than paper, and the wind easily strips them from the branches at this stage. There are lots of theories about why beech leaves keep their leaves all winter, including to discourage deer from eating their buds, but nobody really knows for sure.

This pile of old railroad ties brought back memories. I grew up just a few yards from railroad tracks and seeing all the rails and ties torn up after the trains stopped running hit me almost like a death in the family would have. For many years I didn’t go near a rail trail but then, after some gentle prodding by an old friend, I started walking them. I’ve been glad ever since that they are here to enjoy; they’re much easier to hike than the tracks were.

I saw a tie plate lying beside the trail.

Someone had found an old rail anchor and placed it on a stone. Rail anchors were used, as you would guess, to keep the rails from moving. Eight were used on each 39 foot length of track but their numbers were increased as the grade steepened. Four of them in original as found condition will cost you $36.00 online.

There are a few old box culverts out here, still doing their job of keeping streams from washing the railbed away. This stream had dried up but I think it only runs in heavy rains or when the snow melts.

I was a little apprehensive when I reached this point because this is very near where I met up with the biggest bear I ever want to meet in the woods. That happened a couple of years ago on just about this date but on this day the bear had apparently gone over the mountain.

In case you missed it the first time, here is the bear I saw that day. It was big and it just stared, and that was a bit unnerving. Thankfully it let me leave and didn’t follow. I doubt that I’ll ever forget it.

Grapevines were hanging on to any branch they could grab. This is how they climb trees to get into the crown where there is more sunshine.

I was getting close to where the cohosh grows when I stopped to take this shot. There was bright sunshine when I started out but high thin clouds had made the light flat and strange by this time.

Finally I reached the ledges, cut through the hillside by the railroad, and the mosses glowed.

Marks from the old steam drills can be seen here and there. These holes would have been filled with black powder. You basically lit the fuse and ran, and then you cleaned up all the blasted rock.

I was surprised to find icicles on the ledges but it had been a cold night. They were falling fast after a the sun reached them though, so I had to make sure there were none above me when I got close to the ledges. You can just see a wild columbine to the left of the icicle, and that’s why I wanted to get close to the ledges.

I’m beginning to wonder if they aren’t evergreen. I used Google lens on this plant to see if it could identify it and it came back with Aquilegia canadensis, which of course is correct.

Unfortunately it couldn’t identify this moss that you see covering the ledges because it is so tiny I couldn’t get a shot of it with my phone. I’m still looking through my moss books for it. It forms huge mats here on the stones.

I tried Google lens on this fern and it came back with evergreen woodfern (Dryopteris intermedia), which I think is correct.

Its stalk (stipe) was very scaly and I was surprised that I had never noticed this. I’ve seen scales on lady ferns but there are actually three ferns with scales; spinulose ferns also have them. I haven’t seen any fern fiddleheads yet.

I never did find the blue cohosh but trying to remember where a one inch tall shoot once was in such a large area can be difficult, even though I recognized the stone and log it had been growing near. I’m sure I’ll see the plant with its leaves when I come back to see the wild columbines blooming in early May. Purple trillium, Jack in the pulpit, herb Robert, and many other plants also grow here.

Baby tooth moss (Plagiomnium cuspidatum) lit up a bit of ledge. I can’t think of another moss with so many spore capsules. They start off straight up and pointed like toothpicks and then begin to swell and turn downward. I have it growing in my yard and it’s cheering to see how it glows in the afternoon sunshine.

Cushion moss (Leucobryum glaucum) reminded me of little Miss Muffet’s tuffet. This moss can appear silvery, white, bluish green or grayish green but it always forms a thick cushion and stands out from the mosses that might surround it. It likes plenty of water and shade and grows on rotting logs or on stone when there is enough soil. It is probably the easiest of all the mosses to identify.

How soft and sweet the breeze was, and how warm the sun. I could easily imagine it being an early summer day but anyone who has grown up in New Hampshire knows what a changeable month April can be, and he knows what might seem a soft caress one day could quite likely seem a hard slap the next. Best not to be daydreaming about the coming summer I reminded myself, there was plenty to love about this day.

Last Sunday was a beautiful day for a change, with bright sunshine and relatively warm temperatures for November, so I thought I’d hike a rail trail I know of up in Westmoreland. This is the one I travel in May when I want to see the wild columbines in bloom, but I don’t know if I’ve ever come out here in the fall. That’s a shame; I’ve missed a lot of beauty.

I was a little dismayed but not surprised to see water on the trail. We’ve had a deluge of rain over the past few months and there is water everywhere. Usually though, you don’t find it on rail trails because the railroad built drainage ditches along the sides of the rail bed. They never would have put up with seeing this much water here. It’s possible the drainage ditches have failed because of fallen debris in them, but I don’t know for sure.

The forest that the rail trail goes through is mostly hardwoods like beech, oak and maple with few evergreens.

It’s hard to tell from this photo but these ledges are way up on the top of the hillside we saw in that previous shot. With all that stone warmed by the sun it looks like a great place for animals to den up.

Speaking of animals, this is a known bear area. I’m not sure if these marks were done by a bear but they were as big as my hand and they were on several trees.

The glimpses of sunlit beeches were enough to make me just stop and admire them for a while. Beeches are such beautiful trees, from bud break in spring until their leaves finally fall the following spring, they are year round friends.

There is an unusual box culvert out here that had a lot of water running through it due to heavy rain the previous day. I’ve been out here many times but this is the first time I’ve seen this much water here; usually there isn’t any. The box culvert is unusual because its joints are mortared. Almost every other one I’ve seen was laid up dry with no mortar.  The mortar could have been used in a repair years after it was built though, which is what I suspect. You don’t find much mortar in railroad stonework.

I saw some nicely colored turkey tail fungi (Trametes versicolor) decorating a log. There were hundreds of them. I think my favorites are the ones with blue or purple colors in them.

Of course there were stone walls; there are always stone walls in New Hampshire. Property owners almost always built them along railroads to mark the place where their land ended and railroad right of ways began. The walls here are unusual because they were built largely of railroad cast off stone that had been blasted out of the ledges. If the railroad didn’t use it to build with they often simply dumped it in large piles throughout the woods and landowners picked from them. You can tell by the way there is hardly a round corner to be found in a wall.  The stones have square and angular corners and flat faces, though the section in this photo does have more rounded fieldstones than most of the wall did.

If you look closely you can see the hand of man in the stones. These finger size grooves were made by hand with a star drill or possibly a steam drill. You drilled your holes and then tapped small tools called feathers and wedges into them. The pressure exerted by the wedges would break the stone, leaving a flat face with finger shaped grooves. It was a huge amount of work but once the stone was cut the stone masons used it to build culverts, bridges, tunnels, walls and anything else they needed to get the tracks down and moving forward.

And they’re still building walls out here. They recently logged this land and the loggers built a road to where they had to be. The stones are used as a retaining wall to hold the road up and they’re big. They also have that “new” clean look that tells you they haven’t been there long.

We’re almost there. What looks like a dark tunnel up ahead isn’t a tunnel and it isn’t that dark, and that’s where we’re going.

I saw quite a few maple seedlings still hanging on to their colorful leaves.

I think the seedlings were red maples (Acer rubrum) and I think that because larger maples showed target canker which, if I understand what I’ve read correctly, only attacks red maples. It is caused by a fungus which kills the tree’s healthy bark and the patterns of platy bark seen in this photo are the tree’s response to the fungus. It grows new bark each year in the circular patterns seen here to contain the fungus. Usually the fungus will not kill the tree.

More signs of the railroad; a tie plate with a bent spike still in it was beside the trail. You can find a lot of railroad artifacts by walking rail trails.

And here we are at the ledges where the columbines grow, looking back the way we just came. The stone here is very dark but I have a feeling these ledges have limestone in them because of the lime loving plants that live here.

There isn’t much soil on the stones but there is enough to grow columbines (Aquilegia canadensis) and in some cases even trees. I was wishing I could have seen some of the beautiful red and yellow flowers but I’ll have to wait until next May for that.

I did see some asters scattered along the trail, and though I don’t know their name they were a welcome sight. Any flower is welcome in November.

I wasn’t expecting to find columbines blooming out here but I was hoping to find blue cohosh berries (Caulophyllum thalictroides) and there they were. I found this plant when I came out here in May to get photos of the columbines and a chance to see the beautiful blue “berries” is what brought me back on this day. The berries are actually brown seeds with a fleshy blue coating that protects them, and the seeds are what are considered the plant’s true fruit, so the plant is a bit unusual. Now that I’ve seen the foliage, flowers and fruit I need to come here in the spring, in April I’d guess, to see the beautiful dark blue spring shoots. They look like tiny blue hands reaching out of the soil.

Blue cohosh fruit is actually darkly colored like a blueberry and like a blueberry the “bloom” made up of waxy white crystals that cover the berries reflect the light in a way that makes them appear lighter colored. Some describe them as “blueberries dipped in confectioner’s sugar.” This plant is very rare in this area so I’m hoping these fruits will grow new plants, but deer love eating the plant so the odds are against it. I should mention that, though Native Americans used the roots of the plant medicinally and herbalists still use it today, science says that it has “poisonous properties” and the “berries” can make you quite sick.

Here is a photo of a blue cohosh flower that I took on May 12th of this year, so it’s an early bloomer. Each of the yellow green striped sepals of the flower contains a nectar gland to attract insects.  6 yellow stamens form a ring around the center ovary and the true petals are the shiny green parts that ring the center between the sepals and the stamens. The word cohosh is believed to be Native Algonquin name used for several different plants with different color fruit so in this case the blue refers to the fruit color, even though all parts of the plant including the leaves and stems have a bluish cast to them in the spring.

The trail went on, north to Walpole before crossing into Vermont, but I did not. I turned around, happy that I had now seen such a rare plant in three stages of growth. This is only the second time I’ve seen it and the first time all I saw were the blue fruits, so the hike was well worth the effort. I’m really anxious to see the dark blue shoots in spring, and that probably means that winter will pass slowly. But then I suppose that it always does.

If the sight of the blue skies fills you with joy, if a blade of grass springing up in the fields has power to move you, if the simple things in nature have a message you understand, rejoice, for your soul is alive. ~Eleanora Duse

1. Rail Trail

I’ve decided that what I like most about rail trails is the same thing I liked about them when the trains were running. Back when I was a boy everything was a mystery and new discoveries waited around every bend. I find that little has changed in that regard on these old paths through the forest. I’ve been walking and biking the rail trails in the area over the past few weeks and this year I decided to look for a little history as well as interesting plants. I found plenty of both.

2. Box Culvert

If you’re on a rail trail and see a stream flowing under it, there’s a good chance that it is flowing through a culvert-possibly a very old culvert. The one in the photo is a box culvert, made up of two side walls, top or lintel stones, and a stone floor. In the mid-1800s railroad stone masons cut these stones from ledges or boulders found in the woods near the rail line. There were certain rules that they had to follow. One regarded the thickness of the lintel stones and by how many inches they had to overlap the side walls, and even how much soil would be packed on top of them. These lintel stones were at least a foot thick and supported the weight of locomotives twice a day for over a century.

3. Trestle

Though I grew up hearing everyone call this type of span a trestle, according to Wikipedia this is a Warren-type through-truss bridge. This type of bridge was made of wood, wrought iron, cast iron, or steel. We have several that cross and re-cross the Ashuelot River but trees and shrubs along the river banks are making them harder to see each year. Last year I could see the river from this spot, but not now.

4. Signal Box

This appears to be an old switch box of the kind that would alert the engineer that the through track had been switched to a side spur. Whatever it was, it was powered by electricity. The rectangular base was bolted to a concrete pad and the warning indicators would have been at the top of the pole, but that part had been broken off.

 5. Forget Me Not Colony

One of the largest stands of forget me nots (Myosotis scorpioides) I’ve ever seen is beside a rail trail. You never know what plants you might find along these trails, and I’ve seen some amazing things.

6. Forget Me Nots

Forget me nots are such pretty little things and here they grow happily, way out in the middle of nowhere.

7. Box Culvert

This is another, bigger box culvert. According to a website I found called Historic Stone Highway Culverts in New Hampshire the difference between a bridge and a culvert is the length of the span. (Width of the opening) Anything less than 10 feet is a culvert, and more than that is a bridge. Most culverts are covered by earth fill but the one in the photo surprisingly had very little fill over it. The amount of fill over a culvert plays a huge role in how much weight it can carry.

8. New Culvert

This is an example of a new culvert, recently installed. Will it last for centuries like the box culverts have?

9. Rattlesnake Weed

Rattlesnake weed (Hieracium venosum), one of the rarest plants that I’ve ever found, grows beside a rail trail. I was very happy to see that it is going to bloom this year. Its flowers look like those of yellow hawkweed and, though they aren’t very spectacular, flowers mean seeds and seeds mean more plants.

 10. Arch Street

Sometimes these old rail trails still cross over roads.

11. Tunnel

Way up at the top of that embankment through a break in the trees is where I was when I took the previous photo. Many of these old granite tunnels have been taken down, but this one still stands. My question is, how did the railroad build it? Did they dig a hole through the hillside and then line it with granite block, or did they build the tunnel and then fill in with soil over the top of it? I’m guessing the latter, but can anyone imagine the amount of soil they had to move? It’s staggering to think of it.

The plants growing in the gaps in the face stones are pushing them away from the arch stones (voussoirs) and they really should be removed.

 12. Early Azalea

In my last post I wrote about finding a native early azalea (Rhododendron prinophyllum) out in the woods, and just as I was taking photos for this post I found another growing beside a rail trail.

13. Early Azalea 2

The fragrance of this azalea is really magnificent and it was my nose as much as my eyes that led me to it.

 14. Arched Culvert

What most impresses me about the railroad is how, even out in the woods, the stone masons displayed their extraordinary craftsmanship. They knew when they built this arched culvert that few if any people would ever see it, but they created a thing of beauty anyway. Each one of those stones was split, faced and fitted by hand, using little more than hammers and chisels. That they have stood and stood well since the mid-1800s is a testament to their mastery of the art of stone masonry. Having built with stone myself I am left in awe of their skill and knowledge. Stone arch culverts are rare in comparison to the box culvert, representing only ten percent of the total culverts in New Hampshire.

In part two of this post we’ll see abandoned mills, old railroad depots, rock slime, rusting boxcars and of course, more flowers.

Sometimes you don’t choose the path, it chooses you. ~Anonymous
