Koh-e Baba

thumb|290px|Topographic map of northeastern Afghanistan with Koh-i-Baba on the left The Baba Mountain range ( Bâbâ Ǧar; Kōh-i Bābā; or Kūh-e Bābā; Kōh or Kūh meaning ′mountain′, Bābā meaning ′father′) is the western extension of the Hindu Kush, and the origin of Afghanistan's Kabul, Arghandab, Helmand, Farah, Hari, Murghab, Balkh, and Kunduz rivers. The mountain range is crowned by Foladi peak (or Shah Fuladi) rising 5048 m (some old maps and dictionaries: 5143 m) above sea level, and is located south of Bamyan.

The Koh-e Firoz plateau merges farther to the west by gentle gradients into the Paropamise, and which may be traced across the Hari River to Mashad. To the southwest of the culminating peaks, long spurs divide the upper tributaries of the Helmand River, and separate its basin from that of the Farah River. These spurs retain a considerable altitude, marked by peaks exceeding . They sweep in a broad band of roughly parallel ranges to the southwest, preserving their general direction till they abut on the Great Registan desert to the west of Kandahar, where they terminate in a series of detached and broken anticlinals whose sides are swept by a sea of encroaching sand. The long, straight, level-backed ridges which divide the Argandab, the Tarnak and Arghastan valleys, flank the route from Kandahar to Ghazni. The high jagged peaks above the Hajigak Pass, blue-black and shining, shimmer in the sunlight for they contain an estimated reserve of 2 billion tons of iron ore; Asia's richest deposit. The very steep descent from the Hajigak Pass () with its numerous hairpin bends leads to the sparkling Kalu River, known locally as the Sauzao or Green Waters. It is bordered by poplars and several charming villages.
