NARRATOR: One day after finding a possible tunnel

in the uplands area of Smith's Cove,

Marty Lagina is eager to show his brother, Rick,

and archaeologist Laird Niven what he believes might

be a breakthrough discovery.

Where is it?

Kind of in line with the wall we found last year and a little

bit askew of the cave-in pit.

It looks like it's well-constructed.

But no record of--

No.

He'll have to take a look.

It's right over there.

Hey, guys. - Hey, Marty.

MARTY LAGINA: How's it going?

Looks good.

We're having a good day.

We've got a big timber across there and a big round timber

coming there.

There's one main beam there, Laird, a big thing.

A notched piece came out of here.

Kind of in there.

GARY DRAYTON: And that notched one came when

we took the last scoop out.

LAIRD NIVEN: Interesting, for sure.

And then, Gary, you said you saw a cross member back here.

GARY DRAYTON: Yeah, and it's a different kind.

It's more like a log, kind of similar

to the U-shaped structure lugs.

NARRATOR: A log?

Similar to the ones used to build

the massive U-shaped structure uncovered at Smith's Cove

last year, and which was scientifically proven to have

been built in 1769, over two decades before the discovery

of the Money Pit?

Those logs and the construction

method could be original.

But why speculate?

I think we need to keep digging.

[electronic beeping]

Let's go.

The timbers are interesting, for sure.

MARTY LAGINA: It is suspicious that there's so

many massive pieces right here.

LAIRD NIVEN: Yeah.

I mean, where did they come from?

MARTY LAGINA: Where'd they come from?

Ho!

CHARLES BARKHOUSE: Billy!

Ho!

Halt!

MARTY LAGINA: You got a big chunk of it.

CHARLES BARKHOUSE: Yeah, you got a chunk

of it right there, Bill.

LAIRD NIVEN: Yeah.

RICK LAGINA: That's a big log.

LAIRD NIVEN: That is.

RICK LAGINA: There you go.

Yeah, that's good.

Just come out.

RICK LAGINA: This thing is gigantic.

MARTY LAGINA: Hey, Billy?

You can get rid of that stuff there.

This stuff here?

MARTY LAGINA: There you go.

Smith's Cove has offered up a whole bunch of stuff

that we didn't expect--

structures all over the place.

We're finding out about all kinds of things

that we didn't know were there.

That's big.

That must be the biggest piece of wood we've seen down here.

MARTY LAGINA: Oh, yeah.

ALEX LAGINA: Other than the U shape.

MARTY LAGINA: And I think this is a notch right here.

There's a lot of data adding up to support

that a flood tunnel really exists, and did

exist, here on Oak Island.

And it's going to be well worth digging in and around

those to see what we can find.

There's no doubt about this.

This is a massive project.

We'll dig that big one up and see what happens.
