The Contortion Spur (English for contortion spur ) is a rock spur on the Shackleton coast of the Antarctic Ross Dependency . It is the largest and most easterly of the three rock spurs that loom on the northern flank of Mount Madison near the mouth of the Byrd Glacier in the Ross Ice Shelf . A special feature is a hollow made of white marble and black slate .
The American geologist Edmund Stump (* 1946) from Arizona State University explored it on April 10, 2000 as part of the United States Antarctic Program . Stump named the rock spur descriptively after its twisted shape.
