Skip right to 1:30 in the video. That's when they focus on Puma Punku.

This is blowing my mind.

Aliens be playing tetris on our planet.

There are other videos. If that one interested you, you should check out the others. They say the lines of the cuts in some of the stone are so clean, if you trace a line with your finger... you can cut yourself. Something probably impossible with stone and copper tools.

i dont know what to say to this .... o.X

Pretty cool stuff. I think I might have seen this same show on the History channel. It really is mind blowing how they were able to move, cut and build those megalithic structures with that kind of precision. Puma Punku is starting to garner a lot of attention. It's being referred to as more perplexing and impressive than the pyramids.

In another video, they showed how modern man could try and accomplish what they did. For one of their intricate slabs, it'd take 25 cranes just to lift it up. With the amount of cranes needed, they'd be so bunched up together... they wouldn't be able to move it anywhere.

It boggles my mind.

And this was supposedly built when??

500 A.D.

I am so interested in everything like this, im only mad that I most likely will never know how they accomplished it.

I'm doing some digging, and there are estimates as old as 15,000 B.C. Which is barely out of the stone age. There are more conservative estimates of 536 - 600 A.D.

Some historians think the original city was built when the shore was only 600 feet away. Built before the Great Flood of the Old Testament, the city is one of the oldest on the planet -- if not the oldest.

Evidence that Lake Titicaca was once a part of an ocean exists even today in the abundance of oceanic creatures still living in the salty lake, although it is over two miles above current sea level.

Seems like the idea that it was as ancient as some of the older estimates claim is under some pretty heavy fire, but there is evidence it was a sea port, and there hasn't been a shoreline there in ages.

On the rock cliffs near the piers and wharfs of the port area are yellow-white calcareous deposits forming long, straight lines indicating pre-historic water levels. These ancient shorelines are strangely tilted, although they must have once been level. The surrounding area is covered with millions of fossilized sea-shells. It appears, from the tilting of the ancient shoreline striations and the abundant presence of fossilized oceanic flora and fauna, that a tremendous uplift of land has taken place sometime in the ancient past. Geologists estimate that this happened roughly around 100 million years ago; but the data gathered from archeological and astronomical investigations indicate a different story.

Oceanic creatures live to this day in abundance in the salty waters of the lake, indicating that it was once a part of the ocean, although it is now over 2 miles above sea-level. What appears to be the original seashore is strangely tilted, as if a tremendous geological upheaval has taken place.

Could some cataclysmic event, such as tectonic plate movement have thrust an entire chunk of the continent up in one massive quake? That could also explain the way those huge stones are tossed around like firewood in the ruins. Pretty neat stuff. As far as carving the stone...

This approach can also be applied to the precision-fit Inca walls: Apparantly, the ancients knew a technique to dissolve or soften the stone by use of acid plant extracts! Before you start laughing, take a closer look at these images (click the images to see larger, detailed versions in a new window):

Puma Punku complex at Tiahuanaco, Bolivia.

The approx. 1 cm wide groove with inside a set of equidistant holes is one of many features there, who are so hard to explain, that the whole site is virtually hushed up by the archaeological community. Its just a few hundred meters away from the famous site of Tiahuanaco, but almost never mentioned. If not advanced machining in ancient times is the key to the mystery, then the cast stone theory could provide some answers. It would not be difficult to build a mold with a strip and pins in it, which had to be removed after hardening of the stone.

I can't say how credible my sources are, but it is very interesting.

Great post, Pogre. It amazes me that hardly anyone knows about this place. I only just heard of it days ago. Fascinating isn't the right word for the place. It honestly blows my mind.
