We still have a lot to discover in the ocean. New species, new environments, and shipwrecks we once thought were lost forever are being discovered. The most recent discovery is a piece of wood thought to be from a centuries-old shipwreck that may have inspired the plot of the film The Goonies. Here’s what you need to know.

In the 1985 film, directed by Stephen Spielberg, the characters were taken aboard a pirate ship commanded by One-Eyed Willie. Although the story is obviously fiction, the story was inspired by an actual ship that went missing.

“According to a spokesperson for Spielberg’s company Amblin Productions, the movie mogul used the story of San Cristo de Burgos as inspiration for the film, which is set in Astoria, Ore.” Washington Post reports.

Historians have long believed that the Spanish ship San Cristo de Burgos might be somewhere along the Oregon coast after it disappeared in 1693. A promising find is a strong hint that they were on the right track. According CNNarchaeologists are currently processing wood found along the shore, which they believe comes from San Cristo de Burgos.

“No traps, just the antlers,” said Scott Williams, president of the Maritime Archaeological Society. Washington Post. “The caves are incredibly difficult to get to,” he said. “They are located on a beach accessible only at high tide, and it is difficult to get there through landslides and rock fields.”

It is not yet confirmed that the pieces of wood found are from the long-lost ship, but historians hope more clues will be found in the coming months. The next step in the hunt is to plan a dive near where archaeologists believe the wreckage is with technology that will help them access the hard-to-navigate caves.

“We’re hoping one of our divers will come across a Spanish cannon lying on the ocean floor,” Williams said. “That would be quite exciting!”
