English: Unnamed Sea Stack Off Breigeo Head, Papa Stour (Big Isle of the Priests). At less than 20 metres high this little stack is not as impressive as it's compatriots such as a little down the coast HU1461, but facing out onto the North Atlantic the situation is wild and imposing.

As with most sea stacks, this has probably formed and survived through being constituted from rock that is more solid and stable than that washed out from around them. In many cases this results in providing ideal rock climbing routes in spectacular locations. In this case, the rock visible in this image is of a good solid nature but as can be seen more clearly in 798611 it is overhanging and in addition lacks much in the way of cracks in which to place rock climbing protection. Taken together these would make this an extremely difficult climb even if top roped. The side of the stack facing away to the right of the image is also overhanging, albeit to a lesser extent, but the rock is somewhat green and slimy making it an unattractive ascent route.

Gaining access to the stack also presents some problems. The water foaming around the stack prevents easy access by boat and even on a comparatively calm day such as that pictured here would make swimming to the stack a highly dangerous exercise. The first visit to the top of the stack recorded by climbers is shown in the image 798611. For this, the only viable route to the stack was by Tyrolean traverse.
