Posts Tagged ‘Stilted Trees’

New year’s day dawned sunny but cool, with a promise of warmer temperature later in the day. Since rain had washed all the snow away I though it might be a good opportunity for a winter climb, so I chose Hewe’s Hill in Swanzey. At about 11:00 am the trail across the field was still white with frost and hard to miss.

In the shade the previous night’s frost still clung to the plants.

And there was ice. I had my micro spikes with me but I hadn’t yet put them on because I had a feeling things might be different in the forest.

Some kind soul had built a boardwalk of halved logs over a wet spot. This wet area wasn’t here when I first came here but it seems to have grown over the years. I wonder if foot traffic had something to do with that.

Pretty brocade moss (Hypnum imponens) decorated many logs near the wet area. I often have trouble finding this moss when I do a moss post but apparently that’s only because I’ve been looking in the wrong places.

As I suspected the forest was clear of ice and snow. The snow on the trail had been washed away by rain before people could walk on it and pack it into ice, so we were back to bare ground.

I’ve always thought that the weight of snow was what flattened evergreen Christmas ferns (Polystichum acrostichoides) down to the ground but according to an interesting article in Northern Woodlands Magazine science has found that  some cells in their lower stems die, forming a ‘hinge’ which allows the fern fronds to sprawl on the ground. What they gain by doing so is the warmer ground surface, which may keep them up to 18 degrees warmer than if they remained standing upright.

If you look at the leaflets on a Christmas fern you’ll see that each one looks like a Christmas stocking, each with a “toe.” This and their leathery look and feel make them very easy to identify. The name “Christmas fern” is thought to come from the early settler’s habit of using its fronds as Christmas decorations. Native Americans used them to treat chest ailments like pneumonia and to relieve flu symptoms.

Concentric boulder lichen (Porpidia crustulata) gets its name from the way its black apothecia grow in concentric (or nearly so) rings around their center. The gray body of the lichen forms a crust on stone and that makes it a crustose lichen. They grow in sun or shade and don’t ever seem to change color. This lichen is relatively rare here and I only see them once in a blue moon but here they were; four or five of them grew on a boulder I’ve walked by a hundred times.  As I’ve said before; I’m as amazed by what I miss as what I see.

There are lots of bent trees in this forest and I’d guess they got that way by having other trees fall on them when they were young.

The soil was crunching when I walked on it in places and I knew what that meant…

…Ice needles. Ice needles form when hydrostatic pressure forces 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. I’ve read that each hair thin needle is hexagonal in shape, and that needles have been found that were 16 inches long. The needles in these photos, frozen together into ribbons, were about 3-4 inches long I’d guess. 

There were lots of ice needles along the trail but many had been stepped on, probably by people who heard the crunching but never saw them.

A young tree root grew over a stone and lashed it down.

I stopped to admire the grain patterns on a hollow log. Wood like this is very beautiful in my opinion and I’m seeing more of it everywhere I go.

I saw several stilted trees on this day. Stilted trees grow from seeds that fall on a rotted log or stump and grow their roots around the stump or log. Once whatever it grew on rots away what is left is a tree that looks like it’s standing on stilts. Or about to run away.

And before I knew it there was Tippin Rock, the 40 ton glacial erratic that rocks like a baby cradle if you push in the right spot. Every time I think about all the things that had to happen for this boulder to be here on the summit my mind gets boggled. How thick can a glacier be, I always wonder.

Tippin Rock has a crack but I don’t think it goes all the way through. If it is rocked much more it might though. I’ve seen photos from the early 1900s of people standing by it so I’m guessing it has been rocked for quite a long time.

This was not a day for views, and that was okay. I had forgotten that the sun points right at you up here at this time of day. What looks like brush in the foreground in this shot is actually the uppermost branches of a mature oak tree.

Instead of looking out into the sun I looked down. As always I was fascinated at being so high above the tree tops, and I wasn’t surprised to find that my fear of heights was still healthy and strong.

Of course I had to say hello to my friends the toadskin lichens. Water dripped down the stones and fell on some of them and that meant they were their “normal” pea green color. They will not die without moisture but what you see here is what I think of as their happy state.

Many of them were dry and ash gray. Lichens are very patient beings and they will stay in this state waiting for rain for as long as it takes.

This one was drying out and was partly gray, and if you compare it to the one we saw two photos ago you can see how the shine has gone out of it. The tiny black dots are this lichen’s spore producing apothecia. Toadskin lichens attach to the rock at a single point that looks sort of like a belly button, and this makes them umbilicate lichens. It was once thought that they were a combination of fungus and algae, but science has learned that they are actually composite beings made up of several different organisms.

I hiked over to the ledges and marveled at the silence of the day. Not a bird call, not a breeze, not a chipmunk, no falling ice or water, nothing. But then while I was taking this photo I heard behind me and down below in the forest the loud crash of a tree falling. This was only the second time I’ve heard a tree fall without seeing it, but it’s a sound you can’t mistake for anything else. It always reminds me of the question “if a tree falls in the forest and there’s nobody there to hear it, will it still make a sound?”

I looked down again thinking I might see that fallen tree, and wished I hadn’t. That’s quite a drop.

After the butterflies had flown from my stomach I headed back down the hill and found a lady and her dog who were lost. She walked a lot faster than I do and had passed me a couple times at different spots, and was now coming back up the main trail looking for the side trail that would lead her out of the woods. I pointed her in the right direction and told her which tree and stumps to watch for. I didn’t see her again so I assume she made it home safely. I’ve been lost in the woods just once and I can say  that I’d rather have just about anything else happen, so I think I know how she felt.

If you wish your children to think deep thoughts, to know the holiest emotions, take them to the woods and hills, and give them the freedom of the meadows; the hills purify those who walk upon them.  ~Richard Jefferies
