2014.
In the desolate high desert of the American Southwest,
mysterious ruins stand as a testament
to a great civilization that once flourished here.
The ancient Pueblo peoples,
or Anasazi.
With a population estimated at well over 100,000,
the Anasazi settled nearly 50,000 square miles
of the Four Corners region of Arizona,
Colorado, Utah, and New Mexico.
The highly sophisticated culture
built hundreds of miles of ancient roads,
many converging from all directions to Chaco Canyon.
A ceremonial site,
believed to be one of their most important.
[man]
somehow came onto the engineering principles
to be able to build multistory buildings
such as Pueblo Bonito behind me here.
[dramatic music playing]
They developed the culture here that integrated
the alignments of the buildings
with celestial objects and events
such as the rising of the Pleiades.
The Anasazi were a very successful civilization
up until about the 12th century
when something very strange happened.
There's a great deal of argument
as to what that event may have been.
[ominous music playing]
[narrator]
sometime around 1130 A.D.
all construction ceased at Chaco.
The buildings were sealed.
And the roofs of the ceremonial structures,
called kivas, were burned.
It's fair to say that there were groups that did
move and migrate to other areas.
Those then became the Pueblos and the Hopis.
What is confusing is what happened
to the central part of the civilization.
The ones that were the astronomers
that built the observatories,
where did they go?
It appears as though they simply disappeared.
[narrator]
like author David Childress,
propose that there is, in fact,
more to the disappearance of the Anasazi elders
than a simple migration.
And they claim clues can be found
throughout the ancient site.
On this cliff behind me here at Chaco Canyon,
we have about a dozen unusual spirals
carved into the cliff.
Archaeologists believe that they represent the sun.
But some of these spirals are very unusual.
One even has little spirals coming off of it.
So you have to ask yourself,
are these spirals, in fact, representations
of some kind of portal,
some door to another dimension?
Both the Hopi and the Zuni Indians
say they came from the stars.
[gentle, mystical music playing]
That their knowledge came from the star people,
the star ancestors.
And the Hopi say
portals are marked with the spiral petroglyph.
Portals to a different dimension,
portals to another world.
There are some that believe that may represent the portals
by which the Anasazi and other Southwestern cultures
crossed from this world into their point of origin.
I think there's a possibility that there is a connection
between the alignments of certain celestial events
and the opening and closings of these portals.
The Anasazi is actually not a name they gave themselves.
It was a name that was given to them by the Navajo.
[woman]
"stranger from afar" or "strange enemy."
Something that was separate, apart.
It is possible that the Anasazi
are in another dimension, another timeline,
another planet.
All of these various disappearances
of people over time.
Whether it is the Mayans, whether it is the Anasazi,
you can look through history
and you can begin to see these rhythms.
Advanced intelligences that are behind all of this
are using the planet like a laboratory.
