High-centered polygons in the Sør Rondane Mountains, East Antarctica: Possible effect of ice wedge sublimation

Small high-centered polygons, 3-15m in diameter, dominate moraine fields in an inland cold desert of the Sør Rondane Mountains, Antarctica. They mainly occur on moraine fields at two stages younger than 1Ma. The polygons on the younger moraine (<0.5Ma) generally have an ice wedge surrounded by ic...
