A col in geomorphology is the lowest point on a mountain ridge between two peaks. [1] It may also be called a gap or pass. [1] Particularly rugged and forbidding cols in the terrain are usually referred to as notches. They are generally unsuitable as mountain passes, but are occasionally crossed by mule tracks or climbers' routes.
North of the notch's height of land, the Zealand River flows north to the Ammonoosuc River near the village of Twin Mountain, with the streamflow eventually reaching the Connecticut River and turning south again to ultimately reach Long Island Sound. The notch lies between Whitewall Mountain (3,405 ft./1,038 m.) to the east and Zeacliff (approx ...

A gap is a geological formation that is a low point or opening between hills or mountains or in a ridge or mountain range. 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]
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.
Also island chain. A chain, cluster, or collection of islands in a sea. arête A sharp, narrow mountain ridge, often resulting from the erosive activity of alpine glaciers flowing in adjacent valleys. [2] arroyo. Also wash. A deep gully cut by a stream that flows only part of the year; a dry gulch.
The summit of Crawford Notch in January. Originally called White Mountain Notch, it became known to European settlers when found by Timothy Nash in 1771. [1] The 1772 boundaries of Hart's Grant reflected its shape. [citation needed] It was named for the Crawford family, who were trail-builders and hostelers there in the 19th century.
