Based on the world record nomination from Asia Records Institute (ASRI) and Decision No. WK/USA.INDIA/850/2022/No.306, World Records Union (WorldKings) officially recognizes Khumbu Glacier as World’s highest glacier on May 21st, 2022.
The Khumbu Glacier is located in the Khumbu region of northeastern Nepal between Mount Everest and the Lhotse-Nuptse ridge.
The Khumbu Glacier is followed for the final part of the trail to one of the Everest Base Camps. The start of the glacier is in the Western Cwm near Everest. The glacier has a large icefall, the Khumbu Icefall, at the west end of the lower Western Cwm. This icefall is the first major obstacle—and among the more dangerous—on the standard south col route to the Everest summit. It is also the largest glacier of Nepal.
Khumbu Glacier is typical of many Himalayan glaciers in having a snout almost totally covered by debris. This is derived mainly from rock avalanches, but some reaches the surface from the bed, possibly by thrusting, in zones of compressive flow, such as below the Khumbu Icefall. The debris has the effect of slowing down ablation, increasingly so towards the snout. This has the effect of lowering the surface gradient, and promoting the development of supraglacial ponds. When these coalesce, large unstable moraine-dammed lakes may form, posing a serious hazard to communities’ down-valley.
