Contortion Spur

Contortion Spur

Contortion Spur (80°25′S 160°9′E / 80.417°S 160.15°E / -80.417; 160.15) is the largest and easternmost of three spurs which descend north from Mount Madison near the mouth of Byrd Glacier. The spur exposes a spectacular syncline of white marble and black schist. It was geologically mapped on December 10, 2000, by Edmund Stump of United States Antarctic Program (USAP); he suggested the name because of the skewed form of the spur.
