Like in a dream the rushing water of the Pacific swallows and then releases the lava rocks along the shore. In a photograph, the photographer has a chance to depict this process in multiple ways, showing either the force by freezing the motion of large waves ready to crash on the shore, or the constant transition of the rocking motion in a long exposure where water blurs and provides a semi-transparent blanket for the black lava rocks. And that is just what you can see in this photo from the beautiful Poipu Beach on the south shore of the island of Kaua`i, one of the Hawaiian islands rightfully called the Garden Isle.
Kaua`i is the oldest of the main Hawaiian Islands and fourth largest of the archipelago. The first European known to reach Hawaii was James Cook who landed at Waimea Bay and named the archipelago Sandwich Islands after his patron, the Earl of Sandwich. Later, king Kamehameha I named the islands after his home island of Hawaii (the Big Island).
