Rupshu is a high elevation plateau valley and an eponymous community development block in southeast Ladakh, India. It is between the Startsapuk Tso and Tso Moriri, and west of Mahe.
The Salt Valley and the Puga Valley to its north are also part of the bigger Rupshu area. The Chumar area disputed by India-China in south-eastern Ladakh lies in Rupshu block, south of the Tso Moriri lake, on the bank of the Parang River (or Pare Chu), close to Ladakh's border with Tibet.
The Zanskar Range is a mountain range in the union territory of Ladakh that separates the Zanskar valley from Indus valley at Leh. The range lies between and runs parallel to the Great Himalayas to the southwest and the Ladakh Range to the northeast. Geologically, the Zanskar Range is part of the Tethys Himalaya. There are a number of peaks higher than 6,500 m (21,300 ft). Its eastern part is known as Rupshu.
Kargil district is a district in Indian-administered Ladakh in the disputed Kashmir-region, which is administered as a union territory of Ladakh. It is named after the city of Kargil, where the district headquarters lies. The district is bounded by the Indian-administered union territory of Jammu and Kashmir to the west, the Pakistani-administered administrative territory of Gilgit–Baltistan to the north, Ladakh's Leh district to the east, and the Indian state of Himachal Pradesh to the south. Encompassing the historical regions known as Purig, the district lies to the northeast of the Great Himalayas and encompasses part of the Zanskar Range. Its population inhabits the river valleys of Suru, Wakha Rong (not to be confused with the Rong Valley in Leh district), and Sod Valley.
Kargil district was originally created in 1979, when Ladakh was part of the state of Jammu and Kashmir. In 2003, Kargil was granted a Ladakh Autonomous Hill Development Council (LAHDC). In 2019, Ladakh became a union territory, with Kargil and Leh being its joint capitals. In 2024, the Drass and Zanskar districts were separated out from Kargil district.
