Season 10 of The Curse of Oak Island continues to show new discoveries and theories.

This week on Oak Island they showed the latest developments in the Garden Shaft. They also shared the plan that they had to drill probes of 12 to 20 feet length out of the shaft into the surrounding area to see what they could find. They are now close to the bottom of the original Garden Shaft. The rehabilitation is now at 67 feet of the original 80 foot depth.

They also talked about the start of excavation in what is known as the Quadrilateral. The Quadrilateral is where there is an area of stacked boulders. They started the excavation and of course Gary was metal detecting the spoils. They found some burnt sticks that were similar to ones found under the Stone Road so were talking about possible connections between the two areas.

They also found some blue clay similar to what was found deep in the Money  Pit and were wondering if they were trying to waterproof something?

Of course, one thing to remember is that the dig season is already over. They have taken the time to determine how to present things each week to build suspense and keep viewers tuned in.

Were the boulders and the clay protecting something below? The boulders would stop people from getting below the Quadrilateral, and the clay would help waterproof what was hidden.

They held a video conference with a researcher from Portugal and talked about some of the items that have been found. They also talked about the possibility of treasures being brought to Oak Island from Portugal. In the late 16th century, there was a treasure that disappeared, and it is a possibility that it was brought to Oak Island by the Order of Christ who were associated with the treasure.

They also discussed the old rock wall near the old well. The construction technique was Portuguese and was not used by other countries in Europe.

In the Quadrilateral the clay and boulders are not naturally found in the area they were placed. These would have to have been brought into the area and arranged with a large amount of effort. What were they hiding?

They found a piece of metal in the wall of the excavation of the quadrilateral. It looked like a hand forged staple. Carmen Legge took a look at the staple and said that it would have held guide ropes instead of being used to fasten something and that the staple could’ve come from the Medieval period. An analysis of the metal composition showed that it was old enough to be from that time.

Back in the Garden Shaft, the probe drilling continued with limited results.

They had a meeting with the team and announced that the carbon 14 results of the charcoal that was previously found in the old rock wall had come back. The date came in from the late 15th century to early 17th century which would have been pre-searcher and at the time of the disappearance of treasure from Portugal.

In the preview of the next episode they showed the results of a survey from the swamp that showed a large metallic anomaly. They then showed the start of an excavation in the swamp. They also showed some excitement with the probe drilling in the Garden Shaft.

This episode was titled A Quadrilateral Move and the next episode is titled Ramping Up. Perhaps that next episode will show some exciting results.

How will they ramp up the investigation?
