I’m a bottom crawler. I live on the bottom of the sea. Ach, well, I don’t live in the sea but on land that used to be sea some thousands of years ago. You see, we all are still living in an ice age. The Querternary glaciation, that started about 2,58 million years ago, is still on. We’re just living in a interglacial period, the time between glacial periods when the continental glaciers are at their maximum. So, ice age was not something that happened a long time ago.
The last glacial maximum ended about 11 000 years ago and that’s how long the Finnish landscape has been free of the contenental ice sheet even 3 to 4 kilometres thick. And that is the reason why I am living on an ancient sea floor. All that ice pushed the Earth’s crust down creating a kind of a dent on the crust. When the ice slowly melted away and the ice sheet retreated back towards the north pole, water filled that dent creating a sea. Once free of the weight of the ice, the crust begun to rebound. Post-glacial rebound it is called. That means that every year the land here rises from the sea a little and the actual landmass of the country increases. It’s not much, approx. 5 mm per year, but give it enough time and it will change the face of the earth around here.
So where I now live it used to be sea about 3000 years ago and you can still see it in the landscape. It’s pretty open and level up here. There are small ridges left over by the retreating ice but between them it is rather flat. If you know what to look for, you can see where the ancient beaches have been, and here and there you can see how the now gone see has arranged the sand that once was at the bottom of it into wave like dunes.
I love the openness. The sky is vast, almost limitless. Clouds are the main feature of the landscape and since we are still pretty close to the sea (a bit over 20 km) we get a great variety of clouds here. There are types that you see only during summer and those that herald snow in the late autumn. Even the slightest change in the cloud coverage changes the light, and suddenly you have a completely different mood over the landscape.
The two sketches were made of the roughly same view along our daily dog walk. Nothing much in landscape changed in between except for the sky. The white things in the picture below are huge round hay bales wrapped in white plastic to preserve them for winter feeding. We call them dinosaur eggs – not quite lovingly.
