How long and wide is the Hindu Kush mountain system?

The Hindu Kush is a major mountain system in Central Asia. When defined broadly, the system extends approximately 500 miles (800 km) in length and reaches a width of up to 150 miles (240 km).1

Determining the precise boundaries of the range is complex due to its topography. While the eastern limit is often identified near the Karambar Pass, the western limit is less certain as the mountains gradually lose elevation and fan out into minor ranges toward the border of Iran.2
