Fifteen Million Years of One Idea

July 7, 2026

Back into the gorge at Bellano properly this time. Fifty metres of limestone carved into folds by one stream, walkways bolted to the wall, and the best drawing lesson on the lake.

I gave the gorge one photograph last time and then spent the rest of the post talking about a painter. That was the wrong way round, and I have been annoyed about it since.

Deep inside a narrow limestone gorge, the rock carved into smooth folds and hollows in grey, gold and purple, with a thin channel of pale water running far below — Nobody carved that. One stream did, very slowly, without a plan.

Look at what water does when you give it long enough. Every one of those folds is a decision the stream made and then unmade a thousand times. Smooth where it ran hard, undercut where it swirled, a shelf left standing where the rock happened to be a bit tougher that year.

Fifteen million years, apparently, the Pioverna and a glacier working on limestone and dolomite. Fifty metres deep at the deepest. And the whole of it is a single idea repeated until it became a sculpture.

I keep saying I want to draw movement. Standing in there I realised I have been going about it backwards. This is movement, and it is not moving at all. The rock is a recording of the water. If you want to draw a river you could do a lot worse than draw what it has already done to the thing it runs over.

Eleven seconds. The white bit never repeats and never stops making the same shape. Open full size

Here it is doing the live version. White water dropping through the slot, blue green where it pools, and the rock throwing it left and right all the way down.

Watch it for a bit and you notice the water never makes the same shape twice, but it always makes the same KIND of shape, in the same places. That is the thing. There is a fixed pattern underneath and endless variation on top of it. Which is exactly what a good line does, and exactly what I cannot get when I am trying too hard.

A narrow steel walkway with railings bolted to the sheer wall of the gorge, crossing over the dark slot with the stream far below and ferns growing out of the rock — The whole visit is done on a shelf bolted to the wall. Do not look at your feet.

And you see all of it from this. A steel walkway pinned to the cliff, hanging over the drop, going in and out of the dark. People have been coming here to gawp since the seventeen hundreds, so somebody has been building paths into this crack for a very long time.

It was not always for the view. They put this water to work, ironworking off the Valsassina mines back in the fifteen and sixteen hundreds, and by 1870 there was a cotton mill sitting right beside the gorge. A thing that spectacular, and for three hundred years the main question was how many wheels it could turn.

The mouth of the gorge opening out, with a rust red steel footbridge spanning the rock walls, trees crowding both sides and a calm pale green pool below — Out the far end, where it all goes quiet again.

Then the walls open, a red bridge goes across, and the whole furious thing turns into a flat green pool with trees leaning over it. Thirty metres and it has completely changed its mind.

Same water. Just nothing left in the way.
