Pedestal Rocks - pics

Arizona - but in a creek, so not pure aeolian. Note the many small shards perched on top of it - relics of it weathering away in "skins". Note also the obvious bedding in the layers supporting it

The ultimate product of deflation and wind erosion on Earth is often a Gibber Plain, composed of tightly interlocking pebbles and stones with polished surfaces. This is the erosional lag of hard-to remove fragments analagous to the spherule gravels on Mars.

Those with skill and time may find it interesting to backtrack those pictures to their host pages and see more context.
