A museum in Hawaii is opening a treasure-trove of artifacts from the shipwreck of a royal yacht sunk off the coast of Kauai 191 years ago.

Richard Rogers, a Hawaii shipwreck chaser, has been working with scientists from the Smithsonian Institution to dredge up the findings from the ship owned by King Kamehameha II, aka Liholiho, the second king of Hawaii.

Rogers volunteered his time aboard his research vessel, the Pilialoha, over a five year period in four-week intervals from 1995 to 2001 to pull up the treasures.

Rogers says the king's belongings, including gold, silver, Hawaiian poi pounders, gemstones, knives, and other artifacts, were buried in 10 feet of water and 10 feet of sand.
