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.
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.

The Cumberland Gap is one of many passes in the Appalachian Mountains, but one of the few in the continuous Cumberland Mountain ridgeline. [2] It lies within Cumberland Gap National Historical Park and is located on the border of present-day Kentucky and Virginia, approximately 0.25 miles (0.40 km) northeast of the tri-state marker with Tennessee.
Saddle Peak is the sixth-highest peak in the Bridger Range which is a subrange of the Rocky Mountains. [1] The peak is situated nine miles (14 km) north of Bozeman in the Gallatin National Forest. Precipitation runoff from the mountain's slopes drains into tributaries of the East Gallatin River.

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.
