Another mystery solved

 I have posted pictures of the strange 'beach' at Castlepoint a few time on the other blog with  the following pictures. Apparently, there are similar coastlines near Wellington, too.



I searched many times trying to find out what it was made of but no success until now! It's called 'Miocene sandstone' on one page.

Here are some links if you are interested in how they are formed.

The one title that resonated with me is 'mudstone' - I grew up with Greywacke, (or paparock) and that also is a mudstone, so the beach was haunting me as being 'sort of' familiar.
Those are stunning photos - thank you for sharing

That's a most unusual rock formation. Not good for bathers trying to reach the water.
