Thanks Earl and Chris, I probable walked this bay 1000 times since childhood and never seen a piece like this. Lots of beach glass and potter though.
The town on the ocean side was destroyed by the 1946 and 1961 tsunami's and they decided never to rebuild that part of town again.
Thanks Matthew! sorry I missed your reply earlier. I'm not sure if early Hawaiians used wood bowls. Most of their containers were made from gourds. They used wood for poi boards, war instruments, ceremonial figures, surf boards and canoes. Some bowls were made out of stone as well.
Yeah Surf, its a pretty good piece I'm sure. Look at the size of dukes board! damn thing probable ways a 80 lbs![]
