This looks more like a geological picture for teaching about boulders or glazier erosion.
I have never thought of climbing the Snowdonia mountain in Wales, but on that rainy day in 1985, I did.
It was early Spring when we made our way up Snowdonia. Rain fell as we were laboring our way up the wet, narrow and steep mountain tracks.
After climbing halfway, my shoes were soaked with water and my feet were cold. Parts of the skin on my feet started to peel off.
The bad weather meant that I did not have many good pictures.
This photo brings back memories of an almost forgotten hiking.
