Lumding Glacier, Nepal terminates in Lumding Tsho, a proglacial lake, in Dudh Khosi Valley in the Mount Everest region of Nepal. This lake poses a hazard for a glacier lake outburst flood in the Dudh Khosi valley. The lake expansion results from retreat of the Lumding Glacier. International …

Thulagi Glacier, Nepal Retreat and GLOF Potential

  Thulagi Glacier change in Landsat images from 1991 and 2016.  Red arrow is 1991 terminus, yellow arrow 2016 terminus and purple arrow increasingly exposed bedrock rib amidst icefall. Written With Prajjwal Panday: @prajjwalpanday Thulagi Glacier terminates in a lake referred to both as Thulagi and Dona Lake. ICIMOD (2011) has identified this as a potential threat for a glacier lake outburst flood (GLOF) and has conducted extensive fieldwork there.  Thulagi Lake …

Kanchenjunga Glacier, Nepal Volume Losses

Figure 10-16. Kanchenjunga Glacier (K) from 1991 to 2015, green arrows indicate locations of enhanced supraglacial lakes since 1991. Purple arrow indicates areas of thinning at higher elevations in the region. Location 2 is the main junction area.  Kanchenjunga Glacier is the main glacier draining west from Kanchenjunga Peak, also listed on maps as Kumbukarni. The glacier is similar to Zemu Glacier flowing east from the same mountain into Sikkim, …

West Barun Glacier Retreat Lake Expansion, Nepal

The West Barun Glacier flows southwest from Baruntse Peak at 7100 meters ending at Barun Khola (lake) at 4500 meters. Comparison of images from 1992, 2003 and 2009 indicate the retreat of the glacier and expansion of the lake. In the early 1990’s the lake was observed to be 1100 meters long with an area of 0.66 square kilometers (ICIMOD, 2010). In 2003 the lake was 1500 meters long. In …

Himalaya Glacier Index

Himalaya-Pamir-Hindu Kush-Tien Shan-Quilian-Karakoram Range Glacier Change Below is a list of individual glaciers in the Himalaya and high mountains of Central Asia that illustrate what is happening glacier by glacier. In addition to the individual sample glaciers we tie the individual glaciers to the large scale changes of approximately 10,000 glaciers that have been examined in repeat satellite image inventories. In the high mountains of Central Asia detailed glacier mapping …
