Description: Several doubly terminated Quartz crystals have been found at this locality through the years, only for 2-3 weeks when the tide allows it. A pegmatite runs through the beach and is mostly buried under rocks, but some Quartz crystals are seen every now and then, from 0.5cm to 5cm. (To be confirmed).
