File talk:Geodes in unusual rock formation.jpg

These are not geodes. The resistant pinkish s-shaped object in this photo is a dismembered fold (e.g. http://users.monash.edu.au/~weinberg/Pages/KI_10_SedStruct/KI_SedStruct.htm), a coherent layer that has been broken up by deformation. Geodes would be much more nearly spherical.
