The Preseli Ice Cap might have looked something like this -- this is Drangajokull in NW Iceland. Click to enlarge. This ice cap is very thin and rather inactive today -- in many places you can see the bedrock coming through the ice surface. With climate warming, it's wasting very rapidly, and may be gone within decades. There is one major difference with the Preseli Ice Cap -- this one has had a number of quite substantial outlet glaciers which have been capable of dramatic glacial erosion -- in particular Kaldalon, which runs down towards the bottom left corner of the photo. Ah -- happy days -- I was there in 1960. My first serious encounter with a glacial landscape.
