Tried to build this yesterday but it collapsed 8 times which is why I ended up making the snow sculpture. Went back today and the river level had dropped a lot . Yesterday it was in full spate so the choice of rocks was very limited which made it very difficult to build. Today many more rocks were available and it was slightly easier to construct. The rounded river stones were much harder to work with than the gritstone slabs the other ciarn is made of and it meant I couldn't give it much shape. But I have learnt a lot about working with misshapen rounded stones and the next one I build will hopefully have more curves.
