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.
This can be calculated for a given peak in the following manner: for every path connecting the peak to higher terrain, find the lowest point on the path; the key col (or highest saddle, or linking col, or link) is defined as the highest of these points, along all connecting paths; the prominence is the difference between the elevation of the ...
Saddle – Land connecting two high points; Salt marsh – Coastal ecosystem between land and open saltwater that is regularly flooded; Salt pan – Flat expanse of ground covered with salt and other minerals (salt flat) Sand boil, also known as sand volcano – Cone formed by the ejection of sand on a surface from a central point
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.
