Posts Tagged ‘Falling Ice’

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.

Nature is never static. It is always changing. Everything is in a constant state of flux. Nothing endures. Everything is in the process of either coming into being or expiring.
