1.   Geological features ground out by ancient glaciers are seen overlaid by the scars of recent wind erosion.

2.   Hedgerows and trees help to reduce the effect of wind erosion.

3.   Somewhat softened by wind erosion, the surface none the less looked more like the lunar highlands than like anything on Earth.

4.   The process of soil loss through wind erosion accelerates during droughts, and Southern Africa is currently experiencing the worst this century.

5.   In the desert, rock formations shaped like a traditional building would be torn down, over time, by wind erosion at the base.

6.   Planetary scientists believe it is most likely the product of wind erosion.

7.   The trail ends at Wind Cave, a shallow overhang etched from wind erosion.

8.   Viking scientists, however, maintain that these features are natural geological formations, sculpted by wind erosion and rendered dramatic to the cameras by shadowing.
