HINDU COOSH, or Kori, a range of mountains, physically discriminated from the Himalayas by the vast depression which forms the upper part of the valley of the Indus. They form the N.W. boundary of the province of Caubul, separating it from Balk and Buduckshan. The range of mountains so denominated extends in a westerly direction from Long. 78° as far as the snowy peak of Hindu Coosh, nearly N. of Caubul. These mountains are covered with snow the greater part of the year, and void of verdure at the summit, but are well wooded at the base. They form the Indian Caucasus range of the ancients.
