This is a view of the magnificent rock formations found in Mousetrap Zawn close to South Stack on the North coast of Anglesey.
These rocks are some of the oldest on the world dating from pre-cambrian times some 600 million years ago and form part of the 'Monian Supergroup'. They consist of alternating beds of sandstones and shales with the red rocks showing a higher concentration of iron.
At some point these beds would have been level. However, with millions of years of movement and pressure they have crumpled, contorted twisted and pushed around to now lie at various angles around the bay. In places where the softer rock has weathered away large ledges and hollows have been created, perfect for building nests on and not bad for belays either!
