Spur (topography) in the context of "Tatra Mountains"

The Pennines (/ˈpɛnaɪnz/), also known as the Pennine Chain or Pennine Hills, are an upland range mainly located in Northern England. Sometimes described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the north of the Midlands to Northumberland in North East England. From the Tyne Gap in the north, the range extends south through the North Pennines, Yorkshire Dales, South Pennines, and Peak District to end near the valley of the River Trent. The Border Moors and Cheviot Hills, which lie beyond the Tyne Gap, are included in some definitions of the range.

The range is divided into two by the Aire Gap, a wide pass formed by the valleys of the rivers Aire and Ribble. There are several spurs off the main Pennine range east into Greater Manchester and Lancashire, comprising the Rossendale Fells, West Pennine Moors, and Bowland Fells. The Howgill Fells and Orton Fells in Cumbria are also sometimes considered to be Pennine spurs. The Pennines are an important water catchment area, with numerous reservoirs in the head streams of the river valleys.

A truncated spur is a spur, which is a ridge that descends towards a valley floor or coastline from a higher elevation, that ends in an inverted-V face and was produced by the erosional truncation of the spur by the action of either streams, waves, or glaciers. Truncated spurs can be found within mountain ranges, along the walls of river valleys, or along coastlines.

A faceted spur is also a spur that ends in a triangular face, known as a triangular facet, with a broad base and an apex pointing upward. As typically used in geology, the triangular facet is usually a remnant of a fault plane and it and its associated faceted spur are the result of faulting. The term faceted spur is also applied to inverted-V rock faces formed by stream, wave, or glacial erosion and, thus, as a synonym for truncated spur.
