The mountain range is crowned by Foladi peak (or Shah Fuladi) rising 5048 m (some old maps and dictionaries:[3] 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.

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 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 (3,700 m (12,100 ft)) with its numerous hairpin bends leads to the sparkling Kalu River, known locally as the Sauzao or Green Waters.
