Episode #105: "Kush"
Written By: Damian Kindler
Directed By: Martin Wood
Returning with an abnormal captured in the Himalayas, Magnus (AMANDA TAPPING) and Will (ROBIN DUNNE) are stranded from civilization and aid after their plane goes down in a desolate mountain range. While anxiously waiting for a rescue team, the surviving passengers begin to fall victim to vicious and deadly attacks throughout the night. It becomes chillingly apparent that surviving the cold is the least of their worries and no one, not even Magnus and Will, is above suspicion.
And here are some excerpts from the Wikipedia entry about the Hindu Kush mountain range:
The Hindu Kush is a mountain range located between Afghanistan and Pakistan. The name Hindu Kush derives from the Arabic word meaning "Mountains of India." It is the westernmost extension of the Pamir Mountains, the Karakoram Range, and is a sub-range of the Himalayas. It is also calculated to be the geographic center of population of the world.
The name Hindu Kush is usually applied to the whole of the range separating the basins of the Kabul, and Helmand rivers from that of the Amu Darya (or ancient Oxus), or more specifically, to that part of the range to the northwest of Kabul.
In some of the Iranian languages that are still spoken in the region many peaks, mountains, and related places in the region have "Kosh" or "Kush" in their names. In the Persian language of the Sassanian period, Hindu referred to the inhabitants of the area around and beyond the Indus River, or Hind - the people who were followers of Hinduism. The name is also said to be a corruption of Hindu Koh, from the (modern) Persian word Kuh, meaning mountain. James Rennell, writing in 1793, referred to the range as the "Hindoo-Kho or Hindoo-Kush".
The mountains of the Hindu Kush system diminish in height as they stretch westward: toward the middle, near Kabul, they extend from 4,500 to 6,000 meters; in the west, they attain heights of 3,500 to 4,000 meters. The average altitude of the Hindu Kush is 4,500 meters. The Hindu Kush system stretches about 966 kilometres laterally, and its median north-south measurement is about 240 kilometres. Only about 600 kilometres of the Hindu Kush system is called the Hindu Kush mountains. The rest of the system consists of numerous smaller mountain ranges.
The Eastern Hindu Kush range, also known as the High Hindu Kush range, is mostly located in northern Pakistan and the Nuristan and Badakhshan provinces of Afghanistan. The Chitral District of Pakistan is home to Tirich Mir, Noshaq, and Istoro Nal, the highest peaks in the Hindu Kush. The range also extends into Ghizar, Yasin Valley, and Ishkoman in Pakistan's Northern Areas.
