The Ngozumpa glacier, below the sixth highest mountain in the world Cho Oyu in Nepal, at 36 kilometres (22 mi), is the longest glacier in the Himalayas. Ngozumpa Glacier is a large persistent body of ice. It flows slowly due to stresses induced by its weight.
The Nepali Himalayas are warming significantly in recent decades. Ngozumpa glacier is showing signs of shrinking and thinning, producing melt water. Some of this water pools on the surface where an enormous lake is growing. This lake, called Spillway, has the potential to be about 6 kilometres (3.7 mi) long, 1 kilometre (0.62 mi) wide and 100 metres (330 ft) deep. In the future this might be a threat to the Sherpa villages down the valley.
