Wind Erosion

Arches National Park Moab, Utah

This one is 291 ft across – the size of a football field – the narrowest part is only 6ft wide

Wave Erosion - The process of uplift, fluctuating sea levels, and wave erosion is etched on the rocks of Cape Flattery, Washington. Benches visible just above the current waterline represent prehistoric sea level. Click image for a larger view.

The steep sides of Doubtful Sound (New Zealand) indicate that it is a flooded glacial valley, formed when the world's sea levels rose following the last ice age.
