Ngozumpa glacier

Ngozumpa glacier is a 36km long glacier in the Khumbu region of Nepal. It is the longest glacier of Nepal situated at an altitude of above 4700m near Gokyo Lake. It has been draining from the Cho Oyu, the 6th highest peak of the world.

In recent years, the glacier is showing the sign of shrinking, thinning and retreating, producing melting water. Some of the water is seen to pool on the surface and at the terminus of the glacier, a large moraine-dammed lake is formed. This lake is called Spillway Lake. This lake is guessed to be 6km long, 1km wide and 100m deep and it is still expanding year by year. In the near future, the Sherpa villages down the valley are in a great threat to be swept away by this Ngozumpa Glacier.
