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.

This journey is one of the draws for tourism in the area.A geographic coordinate system enables every location on the Earth to be specified in three coordinates using mainly a spherical coordinate system.
