A 'saddle point' in mathematics derives its name from the fact that the prototypical example in two dimensions is a surface that curves up in one direction, and curves down in a different direction, resembling a riding saddle or a mountain pass between two peaks forming a landform saddle.
Glen – Name for valley commonly used in Ireland, Scotland and the Isle of Man; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Hill – Landform that extends above the surrounding terrain; Hillock, also known as Knoll – Small hill
This is the saddle that gives Blencathra its alternative name, rising beyond the dip to the sixth top, Atkinson Pike. This is the focal point for connecting ridges to Bannerdale Crags and Mungrisdale Common to the north. The ‘saddle’ is bounded by crags to the east, Tarn Crag and Foule Crag being the principal faces.
Idealised mountain pass represented as the green line; the saddle point is in red.. Mountain passes make use of a gap, saddle, col or notch.A topographic saddle is analogous to the mathematical concept of a saddle surface, with a saddle point marking the minimum high point between two valleys and the lowest point along a ridge.

It may be called a col, notch, pass, saddle, water gap, or wind gap. Geomorphologically, a gap is most often carved by water erosion from a freshet, stream or a river. [1] Gaps created by freshets are often, if not normally, devoid of water through much of the year, their streams being dependent upon the meltwaters of a snow pack.
Example on a topographical map, and how it would look in the real world. Typical draw, Little Carpathians. A draw, sometimes known as a re-entrant in orienteering, is a terrain feature formed by two parallel ridges or spurs with low ground in between them. The area of low ground itself is the draw, and it is defined by the spurs surrounding it.
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers. Sometimes a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for ...
