The eye-catching colour of the castle is from the red sandstone, which is finely laminated and shows inpressive sedimentary structures, but that's where the excitement stops. It's only a sedimentaty rock after all.
It was another beautiful sunny day, by the way, Scotland hasn't been treating us as bad as some people suggested it would. Let's hope it stays that way!
Here's the view of Bass Rock, which is turning into one of our favourites!
This is actually a small island along the shore in Dunbar, but it illustrates nicely why Bass Rock is so white. It is not just the birds themselves, as we though first...
We finished our trip with a visit to Yellowcraig, a beach west of North Berwick just opposite Fidra Island (see 13.09.09 for more background).
Also a great place to find barnacles!
