Bow Fiddle Rock is a natural sea arch near Portknockie on the north-eastern coast of Scotland. It is so called because it resembles the tip of a fiddle bow. It is composed of Quartzite, a metamorphic rock which was originally quartz sandstone. This rock is part of the Cullen Quartzite formation which is seen along the coast between Buckie and Cullen. The formation is some 2,400m thick and dates from the Neoproterozoic Era, 1,000 to 541 million years ago.
