Short summary

We present a new map of the surface features of the entire Antarctic Ice Sheet. The map was compiled from satellite images. It shows many flow-parallel structures that we call "longitudinal ice-surface structures". Their location mirrors the location of fast-flowing glaciers and ice streams in the ice sheet. Their distribution indicates that the major ice-flow configuration of the ice sheet may have remained largely unchanged for the last few hundred years, and possibly even longer.
