Certain rock outcrops in the Precambrian of Anglesey are highly enigmatic, notwithstanding their great interest. This rock is what remains of a quarry in a serpentinised gabbro exposure - the interest arising from the idea that magnesium-rich rocks originating as ophiolite, or ocean-floor basalts, have been emplaced during the subduction of the Iapetus Ocean and subsequent continental collision. This view is not held by everybody who has worked on the local geology. A footpath runs along this track, which gives access to a number of houses towards the coast.
