After the cirque's formation by glacial erosion (approx. 3 million years ago), a river channel cut through the base of the valley, creating an Oxbow lake within the cirque, a loop in the river that eroded itself through. An oxbow lake is a U-shaped lake water body formed when a wide Meander from the mainstem of a River is cut off to create a lake The lake later dried up, leaving deposits of silt and peat. Silt is Soil or rock derived Granular material of a Grain size between sand and clay Peat is an accumulation of partially Decayed Vegetation matter. This created what is the only patch of arable land for many, many miles around.
Roads in the area are very poorly maintained and are only suitable for one vehicle to pass on. In order to pass the landform, a dangerous, although exhilerating road which weaves down into the valley and clings to the sheer cliff face on the way back up must be braved. This journey is one of the draws for tourism in the area.
