How do the eastern Pamirs differ from the western Pamirs in landforms?

The Pamirs are divided into eastern and western areas that are distinguished by their contrasting landforms.1

Eastern Pamirs

In the eastern Pamirs, a medium-mountain relief predominates on a high raised foundation. While the absolute heights of the peaks are significant, the relative heights of the mountains above their foundation are generally modest, typically not exceeding 3,300 to 5,900 feet (1,000 to 1,800 metres). The landscape is characterized by:1
* Rounded mountain contours.1
* Wide, flat-bottomed valleys and troughs situated at high elevations (12,100 to 13,800 feet).1
* Valleys and slopes covered by layers of loose material.1
* Quietly running, meandering rivers or dry channels.1

Western Pamirs

The western Pamirs feature a high-mountain, sharply disjointed relief. This area is defined by:1
* An alternation between low ranges and alpine ridges capped by snow and glaciers.1
* Deep, narrow ravines containing high-velocity rivers.1
* Valleys and depressions filled with outwash debris, making human settlement largely restricted to alluvial fans near tributary rivers.1
