Spur (topography)

A spur is a subsidiary summit of a hill or mountain. By definition, spurs have low topographic prominence, as they are lower than their parent summit and are closely connected to them on the same ridgeline. Examples of spurs include:

• Abbott Spur, which separates the lower ends of Rutgers Glacier and Allison Glacier on the west side of the Royal Society Range in Victoria Land, Antarctica
• Boott Spur near Mount Washington
• Kelley Spur, 2 nautical miles (3.7 km) east of Spear Spur on the south side of Dufek Massif in the Pensacola Mountains, Antarctica
• the South Summit of Mount Everest
• Skye Peak at Killington Ski Resort
