Eryri: Snowdonia - Before the Blizzard Hits

Day one: peaks sharp against a pale sky, snow on the upper faces, the ridgeline defined. The view from inside the tent — fabric framing the opening, mountains beyond it, the familiar tent-door framing that is also just what you see when you're lying there looking out. There's a small shelter in the moorland, low and functional, visible against the slope. I shot from it in the wind.

Day two: the fog started at the summits and moved down. The layering-away of the mountains into mist is a process you can watch in real time if you pay attention. One ridge, then the next, then the valley walls softening. The peaks that were sharp the previous morning became approximate shapes, then grey suggestions, then nothing.

I was heading out by the time the snow actually started. But the hour before it — when the fog was down and the light had gone flat and everything was the same grey-white — is the hour this series is about. One frame: Tryfan's flanks disappearing into cloud, the moorland in the foreground still visible, the mountain already half-gone. Another: the valley from low down, the ridgelines layered and receding into mist, no colour distinction between sky and stone.

A mountain stream moving through moorland, the far peaks still carrying some snow. That image is from the first day. You can see the difference between the two days in what the light is doing.

By the time the snow really hit, I was already on the road south.
