 So this is an
anomaly you located.
DAVE BLANKENSHIP: Yeah.
Yeah.
I found it when we're
looking for a deer
back here with [INAUDIBLE].
 Really?
NARRATOR: After obtaining
what is reported
to be a centuries-old map
of Oak Island, Rick, Marty,
and their team are eager
to investigate what
Dave Blankenship
has just described
as a strange depression in
the ground near his property.
 I want to show you guys
that we're in the general area
of the supposed hatch.
Here, let me show you in
the back of the Yukon.
I can project it onto the
French map that Zena gave us.
 OK.
Let's look.
JACK BEGLEY: The
approach I took was
to try to fit the old
French map that Zena gave
us with new satellite imagery.
And so I blew up the old French
map, and it's really close.
And I want to show you guys,
you know, how close it is
and how much it lines up.
 Let's see how bad it's off.
At least the top end of it is--
follows the coastline
the same, parallel.
Look at the top of that.
It follows it perfectly.
It's just offset.
 Yeah.
And we don't know how
much-- that was 1300-- how
much has eroded off the island.
 This is probably as good as
I'm going to get it for now.
DAVE BLANKENSHIP: Jack, yeah.
JACK BEGLEY: The thing is
it is in this general area
right here.
Right underneath it
is where your driveway
meets the main road,
and this little thing
down here is your house.
But right about here
is our search area.
I don't think we
have a very good
description of what
the hatch is even
supposed to look like, right?
 Well, we don't.
But that's where it ties in--
David found an anomaly--
 Yeah, a hole over here.
 --right about
where it should be.
JACK BEGLEY: This hatch lands
kind of where David said--
DAVE BLANKENSHIP: --the hole is.
JACK BEGLEY: Yeah.
 It's close enough.
Let's go look at it.
 Let's go.
 All right, well--
well, make sure I'm going
the right direction.
Where should I go in at, David?
DAVE BLANKENSHIP: Go
in here by the pole.
 Right here?
 Yep.
 Give him a wide berth.
 Yeah, with that thing,
you got that right.
 OK, I think it's clear enough.
We can get through here.
This.
 Yeah, I think this is it here.
Wow.
 Holy smokes.
NARRATOR: Could
the Oak Island team
have just found the
mysterious hatch
that was indicated on Zena
Halpern's 14th century map?
If so, what will it reveal, a
back door into the money pit
or perhaps a gateway
that leads directly
to an incredible treasure?
 That's the oddest thing
on this side of the island.
