Foothills

Foothills are geographically defined as gradual increase in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills to the adjacent topographically higher mountains, hills, and uplands.

Description

Foothills primarily border mountains, especially those which are reached through low ridges that increase in size closer and closer to the mountain,^[1] but can also border uplands and higher hills.^[2]
