Siahan Range

The Siahan Range is a mountain range in the central part of Balochistan Province of southwestern Pakistan. The Siahan Range is primarily made up of limestone and sandstone and was formed when the north western Indian Plate collided with the Eurasian Plate.

The total length of the Siahan Range from Shireza to the western frontier is about 176 miles (283 km). The highest point of the range is on the east and is Razak (6758 ft): other peaks are Mughal Pabb (5979 ft) and Choto-e-Jik (5874 ft); westward the range decreases in height to about 5000 ft.

The Siahan Range, from the term applied to the western extremity of the range, is the name which may be given to the long ridge which separate Kharan from the valley of the Rakshan River and eventually fades westward into the hills of Iranian Balochistan.

The range has never been thoroughly explored. It consists of two ridges:

It is from this range that the name for the whole mass has been taken. It forms the main ridge at the western extremity of the mass, but at the eastern end, a more southerly range predominates.

The eastern end of the range is variously known merely as Band, or as the Kharan-rakshan Lath, while on the west and north of Panjgur it is known as the Koh-e-Sabz. The Koh-e-Sabz is only well defined to the west of the Korkian Pass, from which place it gradually rises to a height of nearly 5400 ft before it is crossed by the defile known as the Tank-e-Grawag. On the other hand, the Kharan- Rakshan Lath descends gradually toward Jang-ja-e-gajiun in Panjgur, and forms the hilly country between the latter place and the Koh-e-Sabz. It follows, therefore, that a traveler to the Kharan plain on the north, from the part of the Rakshan basin which lies to the east of the Korkian Pass, must cross two main ridges, while immediately north of Panjgur he must traverse three, viz. the hilly country consisting of the extremity of the eastern main range and lying between Panjgur and the Koh-e-sabz; the Koh-e-Sabz and the Siahan or Siahan Koh proper.

The northern ridge between Washuk and the valley of Palantak torrent is known as the Cher Dem in the Washuk Niabat of the Kharan District. Its height is about 5000 ft. at its western end a well known peak Hetai, which lies to the west of the Tank-e-zurrati through which the Mashkel River breaks northward to the Hamun Mashkel.
