The recently released episode of The Curse of Oak Island season 8 is titled "Old Wharf's Tale" and it sees the team making another discovery that could be tied to the Money Pit. This time, they uncover a massive wharf in the property of Samuel Ball, a landowner in the 18th century.

This most recent discovery in The Curse of Oak Island season 8 further sparked the fellowship's theory that Ball might be involved in burying the treasure on the island. The team invited Stuart Wentzell, a local in Nova Scotia who worked for treasure hunter Dan Blankenship in the 1970s.

Wentzell told the researchers that he came across a huge sharp-edged stone under the water's surface while he's diving off-shore during the 1970s. He believed that it was used as a wharf since it stretched out to the ocean about 100 feet from the property of Samuel Ball.

This prompted the team to do more digging and enlisted diver Tony Sampson to locate the wharf. Also, the discovery raised more questions about Ball, a slave from South Carolina and became a successful cabbage farmer after moving to the Island following the Revolutionary War.

Ball settled on the island and was said to have owned about 100 acres of land. It hasn't been explained how he got his wealth, but it leads to speculations that he took part in burying the Money Pit. Over the past years, archaeologist Laird Niven has been exploring his property.

In last week's episode of The Curse of Oak Island season 8, titled "Be There or T-Square," the team found what seems to be a secret trap door in the foundations of Ball's house. They also found other intriguing items in his property, suggesting he's a member or had a connection to the British Navy.

This was further fuelled when Alex Lagina found a button for a Royal Navy jacket, which has a gold lining indicating that it may have belonged to an officer. Meanwhile, going back to the discovery of the wharf, Sampson found evidence of two wharves.

The first one is simple and small, with the team calling it as "fisherman's wharf." The second wharf, however, is huge and estimated to be around 75 to 100 feet. In the next episode, titled "Silver Lining," the team will further investigate whether their discoveries are all connected to the Money Pit.
