Spur (topography)

In topography a spur is a lateral ridge or tongue of land that descends from a hill, mountain or the main crest of a ridge. It can also be understood as a smaller hill or mountain range that projects sideways from a larger one. A spur often separates the lower ends of two neighbouring features, and the low ground lying between two spurs is called a draw or re-entrant. Named examples include Abbott Spur, which divides the lower ends of Rutgers Glacier and Allison Glacier on the west side of the Royal Society Range in Victoria Land, Antarctica; Boott Spur, a subpeak of Mount Washington; Kaweah Peaks Ridge, a spur of the Great Western Divide in California's Sierra Nevada; Kelley Spur on the south side of Dufek Massif in the Pensacola Mountains; Geneva Spur on Mount Everest; and the Sperrin Mountains in Northern Ireland. The Wikipedia article is short, so this entry rests on its definition and examples.
