Previous Year Question

Siachen Glacier is located in the eastern Karakoram Range in Ladakh. It lies in the uppermost or northern part of the Nubra Valley.

Geographical Location

• The Saltoro Range lies to the west of Siachen Glacier, while the main Karakoram region lies to its east.

• The upper part of the glacier begins near Indira Col and it generally flows towards the south-east.

• It is approximately 76 km long and is among the longest glaciers in the world outside the polar regions.

• Meltwater from Siachen Glacier forms the Nubra River. The Nubra River subsequently joins the Shyok River, which ultimately joins the Indus River.

Examination of the Options

• (a) East of Aksai Chin — Incorrect: Aksai Chin lies to the east of Siachen; therefore, Siachen is situated west of Aksai Chin, not east of it.

• (b) East of Leh — Incorrect: Siachen Glacier lies to the north or north-west of Leh, not to its east.

• (c) North of Gilgit — Incorrect: Gilgit lies to the west-north-west of Siachen; Siachen is not situated north of Gilgit.

• (d) North of Nubra Valley — Correct: The glacier lies at the northern head of the Nubra Valley and its meltwater feeds the Nubra River.

Important Fact

Owing to its extreme altitude, sub-zero temperatures and difficult terrain, the Siachen region is one of the world’s most challenging military areas. India secured control over important heights in this region through Operation Meghdoot in 1984.
