HU2676 : Black Skerry of Houlma Sound
taken 6 years ago, near to Hillswick, Mainland, Shetland Islands, Scotland
Black Skerry of Houlma Sound
On an anticlockwise circuit of the Ness of Hillswick, visiting the Drongs, passing between the Isle of Westerhouse and Black Skerry brings the first exposure to the swell from the southwest and less inclination to let go of the paddle to take photographs! This one was taken whilst the Isle of Westerhouse (on the left) was still providing some shelter. Although the wind had dropped from the force six and above we'd had at the start of the trip, the open ocean still provided enough swell for us to keep a bit of distance from cliffs, stacks and, most especially, reefs.
The rocks of the island and skerry are, like the Ness of Hillswick itself, dark metamorphic rocks of the Queyfirth Group (Neoproterozoic in age and perhaps correlated with the Dalradian of mainland Scotland). By contrast the cliffs seen on the right at No Ness, are the very red, and much younger volcanic rocks of Middle Devonian age, part of the Esha Ness Volcanic Formation
