Named by early mountaineering guides because of its extraordinary colour. Glaciers once covered this area and as the ice retreats, their meltwaters pick up a variety of sedimentary materials and carry it downstream to depressions surrounded by glacial debris, creating glacier-water lakes like this. The green or turqoise colour is from the finely ground-up rock flour suspended in the water: the scattering effect which the suspended particles has on the light, combined with the reflection of blue sky, gives the water its remarkable blue-green colour.
