Cross-bedded Sand Dune

Cross-bedded Sand Dune
When I was taught geology before jumping ship to oceanography in 1981 one of the basic principles was Uniformitarianism, often paraphrased as 'The present is the key to the past'. This was attributed to John Hutton, although I currently view him more as a mouthpiece for a school of thought than a visionary.

This shot shows a sand dune on the North Wirral coast ripped open by a storm to expose exactly the same structures observed in the sandstone of Burton Point formed some 200 Million Years earlier.

Uniformitarianism is how I can make the assertion that the structures seen at Burton were formed in an aeolian environment.

It certainly looks similar so I guess there were winds blowing sand around all those years ago. I really don't know much about geology but it does sound very interesting :)

Thanks Steve. It is a fascinating science, but back in 1981 oceanography delivered a job that geology couldn't match.

Wow, that's great, a temporary model of the sandstone wall. So what must pappen it bakes together permanintly this way? Careful covering and no disruption for a very long time?

Thanks Sonja. There is always a lot of blown sand here so these small dunes continuously come and go. I took the photograph from the concrete sea defence. Sometimes that gets buried blocking the road behind forcing the council to start digging!
