Meall na Cuilce roches moutonnees, Loch Coruisk, Isle of Skye
The spectacularly rugged Cuillin Ridge towers over the the rounded forms of the roches moutonnees of Meall na Cuilce on the shores of Loch Coruisk, Isle of Skye.
Coruisk (or Coir-Uisk) is one of the most spectacular glaciated basins in Britain. After the Ice Age, as the glaciers retreated, they carved out deep, sharp, V-shaped valleys between knife-edge aretes (ridges) and left behind some spectacular features such as glacial erratic boulders, glacially smoothed and striated rock platforms and textbook roches moutonnees as seen here. Roches moutonnees are formed when glacier ice travels over an outcrop of resistant rock (in the Cuillin, the predominant rock type is Gabbro with Dolerite dykes) smoothing the approaching flank and plucking rock from the retreating flank, leaving a cliff-like, rugged face behind.
