The Irish landscape was formed primarily by glaciers. The area around Monaghan is drumlin country. Low bumps in the landscape more often than not with small lakes between them. It's a strange place to drive through because you can never make out what's ahead of you for more than a few hundred meters. It's also very old. The little hills are deposits left as the huge glaciers rolled across South Ulster during the Ice Age. You never really get a sense of this until you walk these odd little roads.
At the end of September I travelled with a friend down one of them as the engorged early Autumn was trying to figure out why it was still Summer. We heard a knocking sound in the forest to our right. Then we heard it again but this time far away and to the left and immediately right and then left in the distance. There was a short pause and it started again. Louder and much more disturbing it, was directly in front of us then right, softer to the left, and into the distance again. Then it stopped. It felt like the prelude to something. We left quickly.
I had considered climbing the fence and walking into the trees but it really didn't feel like a good idea. Two months later neither of us have the slightest idea what it was. Woodpeckers? The knocking wasn't a call and answer. It was seamlessly followed by the next set no matter how far away they were from each other. The ground settling? It was damp but the regularity and precision was shall we say, unnatural.
I've enclosed a few photos taken at almost the same time as the knocking we experienced. Maybe it was a natural phenomenon. Looking into the trees on that strangely ripe and almost madly fertile afternoon, I remembered that there were monsters here once.
