A half mile down in the waters of Cabo de San
off the western tip of Cuba's Guanahacabibes
marked by red X is a 20-kilometer
square area of
clean, white sand punctuated by tall, megalithic stones or
first reported in May 2001 by Paulina
Zelitsky, Ocean Engineer, Havana, Cuba.
"They (megalithic stones)
are very unique structures. They really are not easy to
understand and I do not have any easy explanation for them in a
natural geological process."

A year ago in May 2001, I first reported
at Earthfiles.com the startling comments made by ocean engineer,
Paulina Zelitsky in Havana, Cuba about her finding earlier in 2000
"possibly a sunken city built in the pre-classic period and
populated by an advanced civilization similar to the early
Teotihuacan culture of Yucatan. ...Researchers using sonar
equipment have discovered at a depth of about 2,200 feet (700-800
meters) a huge land plateau with clear images of what appears to
be urban development partly covered by sand. From above, the
shapes resemble pyramids, roads and buildings." (See Earthfiles

Since then, I have interviewed Paulina and
her husband, Paul Weinzweig, several times about the evolution of
their research and goal to get a specially built robot down to the
megalithic site which could have lights for videotaping and
drilling equipment to sample from the megalithic stone structures.
(See Earthfiles June

1, 2001, December
15, 2001 and December
28, 2001.) The couple operates the Advanced Digital
Communications known as ADC in Canada and Havana which contracts
to perform deep ocean research.
- Originally, ADC had hoped to have a robot on the
ocean floor by the summer of 2002, but its cost of $2 million has
been an obstacle. So far, the National Geographic Society
continues to express interest in adding its resources and media
production efforts to the exploration, but to date no official
contract has been signed. So, Paulina and Paul have taken on other
assignments to pay bills while periodically sending remote
operated vehicles known as ROVs down to pick up small rocks that
lay on thick sand around the large megalithic stone
- Some of those samples have gone to geologist
Manuel Iturralde-Vinent, Ph.D., who works for Cuba's National
Museum of Natural History in Havana. Since early spring 2002, Dr.
Iturralde-Vinent has studied side-scan sonar images and videotape
from the half-mile-deep site and has concluded that he cannot
assign a completely natural geological explanation for the large,
rectangular-shaped rocks that stand up on a vast, white field of
deep sand spread over 20 square kilometers. However, he is waiting
for the first analyses of rock samples expected around July 19th.
Until then, he is reserving opinion about the composition of the
megalithic structures. However, Paulina Zelitsky describes the
structures are polished granite not indigenous to either Cuba or
- This week I talked with both Paulina Zelitsky
and Dr. Iturralde-Vinent about their current research and theories
about what might have happened off the extreme northwestern Cuba
peninsula known as Guanahacabibes.

Digital Communications, Havana, Cuba:
"Samples that we recovered from the ocean
bottom have justified our structures that we call megalithic
structures. The samples are granite stone, completely polished,
with some incrustations of fossils. Fossils of organic creatures
that normally live on the surface, not on the ocean bottom. This
is very interesting because this is evidence that the whole
surface sank to the depth of 700 meters (2,297 feet, or about a
half mile down).
The area has been seismically active for thousands
of years. And what we find on the ocean bottom are fractures from
which the magma and volcanic ash came out. From these structures we
were able to delineate a configuration of the land that sank because
you can see them clearly. The land that sank is very obvious from
our image of the ocean bottom. And you can see bays, like harbors,
and it's all at the depths of 900 and 700 meters.
Geologically, does Dr. Iturralde-Vinent and
others have any idea what happened volcanically? Was it one large
eruption or series of eruptions?
Series of eruptions and as he is saying, it is
still active. A series of eruptions that created major tectonic
movement to such a degree that land is sinking. For example, Cuba
has sank and re-emerged a couple of times! But that was long ago,
geologically. Now, what happened more recently geologically is that
land sank that joined to Yucatan islands between Yucatan and
Cuba, they sank.
Also, geologically and botanically in terms of
organic life, Yucatan and Cuba the extreme northwestern part
of Cuba which is Peninsula Guanahacabibes (Gwan-uh-cah-BEE-buh) are
completely identical. Completely identical. It's the same limestone
and the same organic life and the same botanic and animal
represented. It's very obvious that land that was joining that is
now on ocean bottom is land that was joining Yucatan and Cuba. But
this land was sinking because of tectonic movement which were
occurring. Of course, earthquakes and volcanoes were accompanying
the tectonic movements. Tectonic movement is not something that
moves softly. It is always accompanied by dramatic volcano and
But we saw on ocean bottom where the bays and
coastal lines of the island that sank. We think there was a series
of islands between Cuba and the Yucatan. There could have been
sinking 15,000 years ago.
One area between the fractures. Not on the
fractures. It is between the fractures was left undisturbed and just
sank flat without fractures. On this area, we can observe those
megalithic structures, or constructions. And they have completely
different and independent delineation from geological faults, from
our geology of the sunken land, or the geology of island Cuba.
Completely independent delineation of their own.
As if they came from some place
We don't know yet. But it obviously didn't come
from Cuba. That's one thing. The stone we recovered from ocean
bottom is very polished granite. All of the peninsula of northwest
part of Cuba, all of this peninsula is limestone, very fractured
limestone. So, geologically, it (megalithic granite structures) is
totally foreign to Cuba. But it's also not known in Yucatan because
Yucatan is also limestone, not granite. Granite is found only in the
center of Mexico.
It covers approximately a beautiful, beautiful,
flat, clean area. Nothing else in this area. And it covers
approximately 20 square kilometers of this area. It's flat,
completely flat. Huge white silicon field. In the middle of all of
that are these megalithic structures surfacing out of it.
What is the scientific consensus so far about
how 20 square kilometers could get down a half mile?
The whole island sank. Probably what we think
happened is that Cuba and Yucatan at one historical time were both
joined. But little by little, this land was fractured into islands
and sank to the ocean bottom. So, the land on which we discovered
megalithic structures sank somewhere between 15,000 and maybe 50,000
years ago, which is quite recent geologically.
What for you is the next most important step you
can take to collect one or more samples directly from the megalithic
I wouldn't be able to do any serious work without a
robot to that is working on ocean floor because I need stability in
order to be able to make an opening in the megalithic structures. We
need to make an opening to enter. National Geographic is interested
in investigating the site with submersibles. So that might be
Do the submersibles have the ability to drill
No. Submersibles don't. They just have the ability
to observe with human eyes.
Or video camera, yeah. But it must be operated by
If you can get the special robot constructed and
down there that costs $2 million, you would be able to photograph
with good light and be able to drill into a megalithic
Oh, yes. I would be able to make opening and enter
inside the structures. What I am the most interested in doing is to
enter inside because if there are some artifacts, they should be
inside the structures and not outside.
Then if National Geographic, or other interested
organization, can get funding together, you might be able to go
forward full time on research and get the robot down to both
photograph and drill into the structures?
Yes, that's right. And discover a completely new
page in our history."
Manuel Iturralde-Vinent, Ph.D., Geologist,
National Museum of Natural History, Havana, Cuba, who presented a
scientific paper about the deep water megalithic structures in March
2002 at an International Geophysical meeting in
Havana: "I do not yet know if the
megalithic structures are granite. I have been working with the data
provided by Paulina for three months and I have been observing the
side-scan sonar images, the video images with some samples recovered
from different places within the area with the megalithic stones are
and also from an area located to the south of this
My impression is first that the structures that are
in the megalithic area at the 600 to 700 meter depths, I cannot
explain these structures by any geological means right now. So, I am
not sure that I can find a geological explanation for the origin of
So I'm clear the structures don't fit into
any natural explanation currently?
Yeah, we think that in natural geological terms, I
cannot give a logical explanation now. So, I am not telling that
they are artificial, but what I say is right now I don't have a good
explanation as to the origin by natural cause of these structures.
They might have an artificial origin. But in this case, we are
opening into a very interesting situation because given the depth of
this structures and if we calculate the timing when these might have
been uplifted, it will take us up to 50,000 years ago. (Meaning,
when the land mass now down a half mile might have been above sea
This is if we follow the rules of the normal
tectonic movement as we have been recording them in the past 100
years in Cuba. But these figures are well known in the world. More
or less, the sea floor can move down as quickly as 16 millimeters a
year. That's one of the very interesting issues that are related to
Meaning that the area is still active
seismically and you are seeing that parts of Cuba are still
Current geological knowledge and data indicates
that the area is still very active and sinking even now. We are not
done with this research. We need to still do more research, collect
more samples, provide more observation to be sure about what we are
talking about. But something is very safe to say now is that we are
not dealing with blocks that have been falling down from the slope.
They (megalithic stones) are very unique structures. They really are
not easy to understand and I do not have any easy explanation for
them in a natural geological process. That's my conclusion now. I
need more time and more data before going forward."
