The Biafo glacier is a 47 km long glacier in the mountains of the Karakoram. Including the tribute glaciers, the total length is 66 km.[1] After the Siachen and Fedtschenko glaciers, the Biafogletscher is the third longest glacier outside the polar region.

Location and characteristics

It is located in Gilgit-Baltistan in Pakistan and, together with the 49 km long Hispar Glacier, with which it is connected via the 5128 m high Hispar-La Pass, forms the longest ice system outside the polar region. The glacier connects the two ancient mountain kingdoms, Nagar in the west with Baltistan in the east.

The Biafogletscher is fed by two glaciers east of Hispar La, the Simgang glacier coming from the east and the Lukpe Lawo flowing in from the north, also known as Snow Lake referred to as.

The Biafogletscher penetrates into the valley of the Braldu, which flows from the Baltoro Glacier in the east to the Indus. The glacier tongue lies at an altitude of about 3150 m.[1]

To the northeast of the Biafogletscher lie the Panmah Muztagh mountains, including the Ogre and the Latok group, to the west of the Sosbun Brakk glacier, east of the namesake of the Spantik-Sosbun Mountains.

Pass crossings

In addition to the Hispar La, there are other pass crossings from the Biafo system to the north and east.

Lukpe Lawo

The (Eastern) Khurdopin Pass is located north of Snow Lake, east of Lukpe Lawo Brakk, and offers a high-alpine transition to the Eastern Khurdoping Glacier, which flows over the Khurdoping Glacier to the Shimshal Valley. This valley drains the north side of the Hispar Muztagh, the Shimshal river flows west to the Hunza valley.

Simgang Glacier (Sim Gang)

The Sim La is located directly to the north of the Ogre and connects the southern arm of the Simgang Glacier with the Choktoi Glacier, which flows away to the southeast.

The Skam La lies in the east of the northern arm of the Simgang Glacier and provides a transition to the Nobande Sobande Glacier, which drains to the southeast. This and the Choktoi Glacier unite to form the Panmah Glacier, which flows further south and whose outlet flows into the Braldu River a few kilometers above the Biafogletscher.

The Lukpe La is located in the north of the northern arm of the Simgang Glacier and connects it with the Braldu Glacier, whose outflow also Braldu is called (not to be confused with the aforementioned Braldu River) flows north and east to the Shaksgam valley. Between Lukpe La and Skam La is the mountain Lukpe Brakk. (Lukpe La and Lukpe Brakk are not to be confused with Lukpe Lawo and Lukpe Lawo Brakk.)

tourism

There are several campsites along the lateral moraine of the Biafo. The first three are looked after by the thousand-year-old village of Askole and have running water. These serve as a starting point for guided trekking tours on the slopes of the high surrounding mountains.
