Big Island Hawaii Mahana Bay_P1010033
Layers of hardened molten lava and volcanic rock formed the cove surrounding Papakolea Beach at Mahana Bay. We can see where people have attempted to carve letters into the rock. Mahana Bay is located just north of the southernmost tip of the United States, Ka Lae (South Point) on Hawai'i, the Big Island. It is a beach full of green sand. Further south is Kaulana Bay. The beach was made by volcanic phenomena. Instead of the sand turning black it turned green. Big chunks are called olivine. It is also known as peridot, the birthstone for August.
