Height of Land
Height of land, a region of high ground that may act as a watershed. Heights of land were important in the historic fur trade for their influence on the determination of routes and portages, and they have affected many transportation routes since then. Heights of land were important to native people in demarcating territoriality, as they were later to European colonists. A political boundary, like the boundary between Labrador and Québec, may correspond to a height of land.
