rock, wind and water

Algorta Sandstones: This sediment rocks are tertiary yellow sandstones and very

beautiful due to their capricious shapes. The so-called "tafoni" are spherical cavities

surrounded by a ferruginous crust. These cavities are due water and wind erosion over

the iron oxide nodules present in concentric layers in these rocks. Other shapes found

here are the 'beehives' which result from wind erosion.

good shot

The shifting light and shadows as it interacts with the pitted, rough surface is excellent. A very good natural abstract.
