Karachukar Valleyor Chalachigu Valley (Chinese: 卡拉其古河谷) is a valley in Taxkorgan Tajik Autonomous County, Xinjiang, China.It contains the basin of the Karachukar River, a tributary of the Tashkurgan River,and is regarded as part of Taghdumbash Pamir.The valley borders Afghanistan (Wakhan Corridor or Little Pamir) to the west and northwest, Tajikistan to the north, and Pakistan (Gojal or upper Hunza) to the south. The name of the valley is from Kyrgyz, meaning "black cave".

The valley is part of the Taxkorgan Nature Reserve. The protected Marco Polo sheep is only found in the wild around this area. The region is often referred to by the Chinese as the Chinese portion of the Wakhan Corridor. There is an ethnic Kyrgyz village called Bayik (Chinese: 排依克村 or Chinese: 阿特加依里村).

Tegermansu Pass or Tigarman Su Pass (Kotal-e Tegermansu, Chinese: 托克满苏山口) is a closed mountain pass on the border between Afghanistan and China in Wakhan Corridor, in the Hindu Kush — Pamir mountain range. It is located between the Tegermansu Valley on the eastern end of the Little Pamir and Chalachigu Valley in Xinjiang, China. Historically, it was one of the three routes between China and Wakhan.

On Chinese side, there is a Chinese border post in the valley below. There have been proposals and plans by Kashgar regional government to open this pass as a port of entry for economic purposes since the 1990s. However, this has yet to happen.

The central Afghan highlands, or the Afghan Highlands (Dari/Persian: افغانستان کوهستانی; Pashto: غرنی افغانستان), is a geographic region of Afghanistan. Stretching from the Sabzak Pass near Herat in the west to the Little Pamir in the northeast, it includes the main Hindu Kush range and forms a western extension of the Himalayas. It is a highland area of more than 1,500 m (4,900 ft) above sea level, mostly situated between 2,000 and 3,000 m (6,500 and 9,800 ft), with some peaks rising above 6,400 m (21,000 ft). Usually, the valley bottoms in the area are used for cereal and horticultural production, and the mountains and high plateaus are used as pasture in summer for grazing sheep, goats, cattle, and camels. Its total area is about 414,000 km (160,000 sq mi).

The region contains about 225,000 km (87,000 sq mi) of summer pasture, which is used by both settled communities and nomadic pastoralists like the Kuchis. Major pastures in the region include the Nawur pasture in northern Ghazni Province (whose area is about 600 km at elevation of up to 3,350 m), and the Shewa pasture and the Little Pamir in eastern Badakhshan Province. The Little Pamir pasture, whose elevation is above 4,000 m (13,000 ft), is used by the Afghan Kyrgyz to raise livestock.
