Why do mountain passes often become travel routes?
HistoryMountains
Quick Answer
Passes are the lowest gaps across a mountain barrier, so they reduce climbing and energy use. People and trade routes naturally concentrate there.
The Full Story
A mountain pass is a lower point through a range, usually shaped by erosion, glaciers, or tectonic structure. Because it offers the easiest crossing, it becomes a natural corridor for roads, railways, migration, and trade. Famous examples include the Khyber Pass between Afghanistan and Pakistan and the Brenner Pass in the Alps. Throughout history, control of passes has been strategically important because they connect otherwise separated regions.
