More wood.

Post at the bottom.

Did you see that rush of water come in down there?

Na-uh.

No, it's still coming in.

Can you see that?

No.

Walk more over there.

I'll grab your belt buckle.

Oh, yeah.

You can see it squirting up like a geyser.

Here, stand where I am.

Oh, yeah.

Yeah.

It's freaking awesome.

Marty, come look at this.

NARRATOR: After being alerted to the discovery

of a potential flood tunnel in the uplands near Smith's Cove,

possibly the same one identified by recent seismic imaging,

Marty Lagina joins Craig Tester, Jack Begley, Gary Drayton,

and Billy Gerhardt to inspect the site

and continue the investigation.

The water's squirting up from the bottom.

You'll see it in the back corner.

Oh, yeah.

Do we know if it's fresh or salt?

Don't know.

Can't say that we found the flood tunnel itself.

But what I see and hear is a lot of water rushing in.

And it appears to be rushing in from the uphole side, in other

words, from the landward side.

This, to me, is very impressive.

The base is giving a little bit.

Yeah, and you can see a crack up in through here.

Yeah.

NARRATOR: Suddenly--

Oh, wow.

That whole edge is about to go.

Oh, man.

Yeah, let's go.

Yep.

This is all getting kind of dangerous.

Yeah, this is nutso.

That was a big enough piece where

that whole bridge could go.

Yeah.

Yeah, we're getting out of here.

It's not worth it.

NARRATOR: Unfortunately, for the team,

the flood tunnel did what it was designed

to do more than two centuries ago,

frustrate the efforts of would-be treasure hunters

to shut off the flow of water to the booby trapped system

that guards the Money Pit.

It's all caving in now.

He's lost a ton of hole.

He's lost a ton.

Do we need to see anything more there?

I just think it's going to cave in too fast.

I'd say put enough in there to make that stable.

Yeah.

Hold on, mate.

Let's reposition.

NARRATOR: In order to stabilize the area

against further cave-ins, the team

will now need to act quickly in order to backfill the hole.

Unfortunately, this also means that any further digging

in search of the main flood tunnel

will have to wait until the ground has settled.

We take some risks out here, and this is a dangerous place.

It would just be foolhardy to keep digging.

It wouldn't have made any sense.

It was sloughing all the time.

Dead hit.

Suddenly, you got [inaudible] water.

You can put a line on that and towards the Money Pit.

I think we may have to give up on that one.

For now.
