Into the Icebox

Finding ice baubles along the shore of the Ashuelot River last week made me wonder if the ice was growing at the deep railroad cut called the “icebox” up in Westmoreland, so last Saturday I decided to go and have a look. There was ice on the man-made canyon walls but it was too early for the ice climbers who named the place to be here.

Broken ice at the base of the ice falls told me that the icicles had formed and melted a few times. It takes a good cold period to get them going but once they start growing in earnest, they can reach the size of tree trunks in just a few weeks.

The groundwater that seeps through the fractures in the stone never stops. Winter or summer, it still flows. The reason the ice grows so well is because, the walls are shaded in this part of the canyon. The canyon rim is 50 feet high in some places, so sunshine might kiss the canyon floor for an hour each day. That’s also why you find no plants growing here.

In this photo from a few years ago you can see the scale of the place and you can also see that the ice climbers don’t wait long to start climbing. These are very focused, intent people and I don’t like to bother them when they’re up there.

In places water pours from the walls in streams but in most places it just seeps slowly, drip by drip.

Never was moss so green as it was on this day.

As you can imagine it is cold here, usually made colder by the breeze that blows through, so the 28 degrees F. I started with was probably more like 18 or 20 when I finally turned south to find some sunshine.

The railroad engineers had a lot of stone to get rid of once the canyon had been blasted through the hillside and one of the ways they got rid of it was to build massive retaining walls along sections of railbed. For the most part they’re still in perfect shape after 150 years.

The southern canyon’s walls aren’t quite so high so more sunshine pours in, and that means more plants grow here on the southern end. At this time of year it seems kind of empty but in summer the growth here is lush, with every vertical and horizontal surface covered by growing things, and it always reminds me of the Shangri-La that James Hilton described in Lost Horizon.

Last summer I discovered ostrich ferns (Matteuccia struthiopteris) growing here and here was the evidence; their feather like fertile fronds, covered with spore capsules. There will most likely be more of them here in the future. They’re a beautiful fern so I hope so.

There are lots of blackberries growing here as well and most still had leaves to show off.

But just because the sun shines brighter here in the southern canyon, that doesn’t mean that ice doesn’t grow here. The cold wins out over the weak winter sunshine and these walls are often trapped under ice that is feet thick until spring.

To give you a sense of what I’m talking about, here is the southern canyon in March of 2015. The ice columns, stained various colors by minerals in the groundwater, were thicker than tree trunks. It’s a good idea to wear warm clothes if you come here in winter.

Until and unless the drainage channels freeze over the ice, no matter how big it might get, is cutoff by the flowing water.

You can see how easily the groundwater can flow through the cracks and fissures in the stone. That’s what makes this place so special. I’ve been in other deep cuts but none have had ice like I find here. Everything has come together perfectly to create a land of water, stone and ice.

Here was new mineral staining that I hadn’t seen before. If an ice column grows in this spot, it will most likely be orange.

An evergreen fern grows in a grotto, set back from the face of the wall and each year icicles, like prison bars, surround it until spring.

But I’m getting a bit ahead of nature, because in other places the ice was rotten. 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. Instead of a sharp ringing crack when it is struck it produces more of 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. Compare the ice in this shot with that in the previous shot and the difference will be obvious.

There was puddle ice to see. Do you see the fish?

In one spot on the wall of the southern canyon a green alga called Trentepohlia aurea grows. Though it is considered green algae the same pigment that colors carrots orange makes green algae orange. It’s is very hairy, but with the drainage channels filled with water I couldn’t get close enough to show you.

Reptilian great scented liverworts (Conocephalum conicum) also grow on the southern canyon walls. This beautiful liverwort gets its common name from its fresh, clean scent. It will only grow near water that is very clean and it grows here just above the drainage ditches. Groundwater constantly splashes them and keeps them wet in warm months. In winter they are often encased in ice, and they will stay that way until spring. It doesn’t seem to hurt them any because there are thousands of them growing here.

The saddest thing I saw on this day was how the trail had flooded over half the length of the southern end. Nobody has maintained the drainage channels enough to keep them fully open and with all the rain we had over last summer they failed and flooded the trail. Snowmobile clubs try to keep up but there is only so much they can do with hand tools. To fix this properly now you’d have to bring in truck loads of gravel and heavy equipment to restore the drainage channels to the condition they once were in. It won’t be easy or cheap but I hope someone will do it because it would be a shame to lose this one-of-a-kind place. There is simply nothing else like it in this area.

All of the water in the drainage channels becomes a stream that runs off into the woods under that old bridge, and I was shocked to see how much soil had washed away from its banks. What was once a little surface stream is now about two feet below the surface.

I don’t know what this old bridge was used for but there was a lot of stone to be moved out of the canyons and I’m guessing that it was wheeled across this bridge and dumped in the woods. The railroad did that a lot and you can find piles of blasted stone all over this area. If I could find a way out there I’d go and see, but nobody is crossing this bridge unless they’re a tightrope walker.

And then there was the old lineman’s shack which, with its ridge beam broken, can no longer support its own weight. It now tilts at about 30 degrees, and if we have any mentionable amount of snow this winter I think it will surely come down.

It looks to me like the heavy slate roof is actually pulling what’s left of the building apart. It’s a shame that something so well built has to give itself up in this way but with absolutely no maintenance over a century or more, it has put up a good fight.

Though the old shack is beyond repair I hope the townspeople will somehow vote to find the funds to repair the damage to the trail itself one day. Other parts of the rail trails that surround Keene have had extensive work done to them, but they’re closer to town so more people use them. Meanwhile I’ll continue enjoying the place for as long as I’m able. I hope you enjoy seeing it as well. It’s a rare and special place that should be appreciated more than it is.

It’s amazing how quickly nature consumes human places after we turn our backs on them. Life is a hungry thing. ~Scott Westerfeld
