南極高原
The McMurdo Ice Shelf and the Antarctic Plateau are relatively stable. Most crevasses occur in the short steep shear zone between them, where the road climbs along Leverett Glacier from near the southernmost point of Ross Ice Shelf to the Polar Plateau more than above sea level. This section of the road needs maintenance each season. The section caused much more construction work than planned, because the ice sheets are likely to move.
