Across the street from Foodland on the North Shore of Oahu, buried beneath 10 feet of sand, lies a slab of lava rock that bears a glimpse into the lives of the ancient Hawaiians. And occasionally, under the right conditions, that volcanic hunk of rock will provide a fleeting history lesson.
Petroglyphs are a form of ancient art or storytelling made by carvings in rock. In Hawaii, the natives used the islands’ abundant lava rock as their canvas. And thanks to El Niño, and this winter’s particularly heavy swell activity, the rarely seen rock formations have been revealed on multiple occasions. Most recently, the swell that fueled the Quiksilver in Memory of Eddie Aikau event at Waimea Bay removed 10 feet of sand up the road at Keiki Beach, which unearthed a petroglyph.

Thanks for posting the link. I must have missed that thread when you posted it. I knew there were those types on the islands but this was the first I heard of the beach ones in lava.

What's most interesting is that carbon dating takes these back 850-1900AD..

I thought this was pretty interesting. I never knew these existed and am pleasantly surprised to read about them. I thought I'd pop in and post a link for those here who like these types of finds.
Pretty cool
I was thinking the same thing. Rosinitiate, could you explain how the glyphs in your Linked Thread were dated. Dating seems to be difficult at best so any technique is interesting.

They weren't carbon dated. You can't carbon date lava. They're dated by style.

Among the most significant new findings—information that was not scientifically proven in 1991—is the age of the rock carvings found along the Ala Loa Trail (more commonly known as the King’s Trail) at Waikoloa. Using Carbon 14 dating, Professors Ron Dorn and Nicole Cerveny of Arizona State University’s Geology Department have determined the oldest petroglyph in the Waikoloa field was created in 840 AD and the most recent in 1900, according to Kwaiatkowski.
“I believe petroglyph-making remained active and wide-spread in the islands just prior to the arrival of Captain Cook. For some unknown reason, after the arrival of Cook and all those other guys (early explorers), it died off relatively quickly,” he says.
What we do know, he said, through both scientific carbon dating and distinctive carving styles, is the progression of more and more sophisticated art forms, the earliest being linear stick-man drawings, which then moved to a brief period of block-like, wide-bodied forms. Both of these styles, Kwaiatkowski says, are found used by ancient cultures worldwide. The most recent pre-contact drawings use triangular forms unique to the Hawaiian k‘i‘i pōhaku.

It says both Carbon 14 dating and stylization. Maybe the dated debris wood, etc, not really sure. Maybe worth you looking into?
