Contortion Spur
# Contortion Spur

Contortion Spur (80°25′S 160°9′E﻿ / ﻿80.417°S 160.150°E﻿ / -80.417; 160.150) is the largest and easternmost of three spurs which descend northwards from Mount Madison near the mouth of Byrd Glacier in Antarctica. The spur exposes a spectacular syncline of white marble and black schist. It was geologically mapped on December 10, 2000, by Edmund Stump of the United States Antarctic Program; he suggested the name because of the skewed form of the spur.
