Shifting sands on Hawaii's Waianae coast have revealed petroglyphs that some experts believe date back hundreds of years.

Petroglyphs are carvings in stone. These etchings have been made in sandstone. The state's Department of Land and Natural Resources and the US Army are working to record and preserve the recent findings.

Scientists are intrigued by the design of the petroglyphs. Typically, carvings are about a foot tall, but the ones discovered in Hawaii are between 4 and 5 feet tall.

A Texas couple stumbled upon the engravings in July while walking along the beach to watch the sunset.

Scientists are urging people to not come too close. Even scrapping sand off the petroglyphs can damage the carvings.
