These pictures all come from a correspondent who prefers to maintain her anonymity behind the alias Bogtrotter. There's nothing boggy about these pictures, taken on the beaches to the east of Mingary Castle.
This picture, of a type of rock fairly common along one section of beach, comes with the request to know what formed it. While Bogtrotter suggests it may be tree roots, my guess is it's mud cracks, this being a rock of Jurassic age formed in arid conditions in pools along a coastal area which periodically dried out.
Our photographer certainly has an eye for an artistic opportunity provided by an old tree trunk washed up along a pebbly beach.
However, of all today's pictures I am most envious of this one. Co-incidentally, I saw a small group of long-tailed tits today but none of them was prepared to stay still long enough to allow a picture.
