We had a good long coast path walk which included this large arch stack at Mouthmill. It's a great location for geologists to drool over goniatite fossils, anticline structures and the upper carboniferous crackington rock formation (a 1970's prog. 'rock' group.) The tide and light weren't especially helpful so I had to clamber carefully over boulders and stone to try and get this wispy cloud to line up.
Extra 1: Can't see the trees for the wood. 
Extra 2: Well, it is Friday after all.
