Height of land
The term height of land is used in Canada and the United States to refer to the divide between two river basins. The term "height of land" was frequently used in border descriptions, where borders were set according to the "doctrine of natural boundaries". In glaciated areas it often specifically refers to the low point on a divide where it is possible to portage a canoe from one river system to another.
