Punaluu black sand beach, Hawaii 1980

Punaluu Bay on the southeastern Puna coast of the Big Island of Hawaii, has a famous black-sand beach formed when molten lava reached the ocean, cooled rapidly and exploded into tiny black fragments that make up the sand. Once the site of a major traditional Hawaiian settlement, and then a sugar port, Punaluu is now a refuge for green sea turtles and hawksbill turtles and is a popular tourist spot.
