Why?!

An early start for Tricia leaving before 9 am to meet up with some others for a swim in the sea. Grey and raining, it must have been a pleasure.
Suddenly at lunch time however, the wind dropped out, the sun came out and off we trotted to a remote corner of South Uist that I've never visited before. 
Right at the end of the track we followed, this anchor was placed on top of a hillock. 
Perhaps a meið to help fishermen into the narrow bay nearby? 
Perhaps a marker of a grave?
Either way an interesting and beautiful spot.
