Do you know the Goeschenen Thal?
There is a semicircle of mountains, the Winterbergen, which closes it in at the head.

We climbed there together for a week, just he and I and no guides.
I remember a rock-ridge there.

It was barred by a pinnacle which stood up from it--'a gendarme,' as they call it.

We had to leave the arete and work out along the face of the pinnacle at right angles to the mountain.
There was a little ledge.

You could look down between your feet quite straight to the glacier, two thousand feet below.
