To go out onto the moor and hills is to adventure through a legacy of monumental forces which are hard to grasp in terms of human time scale and equally hard to visualise. Mountains are thrust up and carved down by the power of water in both its liquid and frozen states; forests grow, then die as climates change over millennia. One landscape gives way to another, time after time, in a fractal world where a whole continent is mirrored in a tiny detail and the micro reflects the mega. Contemplating the trail left by glaciation and climate change over aeons is a fascinating and tantalising challenge to the imagination. Dùiltean is my response to that challenge.
