Himalayan Glacier Change Index

Himalaya Range Glacier Change Below is a list of individual glaciers in the Himalaya 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 Himalayan Range, stretching from the Karokaram Range in NW India east south east to the border …

Khatling Glacier Retreat, Uttarakhand, India

Khatling Bamak (Glacier) is the headwaters of the Bhilangana River in Uttarakhand, India. The Bhilangana River flows into the Tehri Reservoir(2400 MW), that along with the Bhilangana River’s three small hydropower projects (50 MW), make these glaciers key contributors to regional hydropower. The glacier was formerly joined with the Ratangrian Glacier as indicated by the map, but the two have separated with the Ratangrian Glacier now terminating 1.7 km upvalley …

Middle Lhonak Glacier Retreat, Sikkim, India

“Middle” Lhonak Glacier is an unnamed glacier between North Lhonak and South Lhonak Glacier near the border of the state of Sikkim in India and Nepal, red arrow on first map. I have previously reported on the retreat of South Lhonak Glacier whose retreat has led to a significant proglacial lake expansion and nearby Changsang Glacier. Here we examine landsat and Google Earth imagery from 2000-2013. Like all glaciers in …

Kalabaland Glacier, Retreat, Uttar Pradesh, India

Kalabland Gal (Glacier) in Uttar Pradesh, India drains into the Goriganga River, via Ralam Gad. The glaciers flows southeast from the Peak of Chhiring We, joins the Yankchar Glacier and turns sharply southwest. The combined terminus is referred to as Shunkalpa Gal, but here since Kalabaland is the largest contributing glacier, that name is applied to the terminus as well.

Jaundhar Bamak Glacier tributary retreat, Tons River, Uttarakhand, India

The Tons River is in Uttarakhand India. The watershed is fed by more than 50 glaciers. The largest are Jaundhar Barak and Bandarpunch, the glaciers of Tons valley are notable for a thick mantle of debris cover, due to the terrain characteristics, and the avalanche fed nature of the glaciers (Pankaj et al, 2012). The Tons River Basin has one significant operational hydropower unit, the Mori Hanol Hydro Power Project …
