Ancient Peru pyramid spotted by satellite

New remote-sensing technology reveals huge structure beneath surface

A new remote sensing technology has peeled away layers of mud and rock near Peru's Cahuachi desert to reveal an ancient adobe pyramid, Italian researchers announced on Friday at a satellite imagery conference in Rome.

Nicola Masini and Rosa Lasaponara of Italy's National Research Council (CNR) discovered the pyramid by analyzing images from the satellite Quickbird, which they used to penetrate the Peruvian soil.

The researchers investigated a test area along the river Nazca. Covered by plants and grass, it was about a mile away from Cahuachi's archaeological site, which contains the remains of what is believed to be the world's biggest mud city.

Via Quickbird, Masini and colleagues collected high-resolution infrared and multispectral images. After the researchers optimized the data with special algorithms, the result was a detailed visualization of a pyramid that could not be spotted using conventional imagery.

The discovery doesn't come as a surprise to archaeologists, since some 40 mounds at Cahuachi are believed to contain the remains of important structures.

"We know that many buildings are still buried under Cahuachi's sands, but until now, it was almost impossible to exactly locate them and detect their shape from an aerial view," Masini told Discovery News. "The biggest problem was the very low contrast between adobe, which is sun-dried earth, and the background subsoil."

In this satellite image, the white arrows show the buried pyramid and the black arrows other structures which have yet to be investigated.

I can’t believe no-one has spotted this before. It’s bright blue for heaven’s sake!

A pyramid built down into the ground?

[camle]

must be a couple of hundred feet deep at the bottom, and the bottom lines are as clearly delineated as the sides.

also, doesn’t it look like it is tilted? from high altitude it wouldn’t look so much in profile would it?

something doesn’t seem quite right.

[BGHater]

Earthquakes and vault lines, along with vegetation and other natural conditions might have altered the feature.

well.it is hard to really see elevation from an overhead location,but it probably is a mound like hill,the sat is showing disturbance of soil which contrasts with surface,,,I am not an expert,but I mess around with maps alot.

earthquakes and faultlines, yet the outline of the ‘pyramid’ is perfectly straight? sure.

wanna buy a bridge? the more I think of it the less I like this ‘pyramid’ story.

[Bigh4u2]

This might give us a clue...

"We know that many buildings are still buried under Cahuachi's sands"

let's look at a few things here. the arrows in the pic depict three objects. the smallerst object to the left is too small for me to make out, but the other two appear like pyramids, but at vastly different angles. the fact that the bottom of the pyramids must be dozens, or even hundreds of feet deeper that the tops, yet the image has no corresponding deteriration of quality make me suspicious, as does my earlier comments abotu the lines etc being perfectly straight.

Also one must wonder how long these objects have been buried, how long the process of burial involved, and any difference in weatherins from bottom to top is evident, or should be evident.

finally, the middle and right hand 'pyramid's have two sides visible. note that one each of the two sides is significantly darker than the other. would this be evident in a survey of buried objects, or should both visible sides be the same? It looks more like a shadow.

ping me when they dig it up and prove it, but for now I just don't buy it.

[camle]

how deep are these sands?

[stockpirate]

It’s buried under the mub, as in completly covered up.

LOL~! you left out bigfoot. the lines of trees appear to be at a more or less equal elevation. that mens that if there really are pyramids beneath the sand, there must be a heck iof a dropoff in a very short area, like a cliff or very deep gorge. and we know that at the bottom of any deep gorge there is a river (think grand canyon). if this is true, then both visible pyramids straddle where the river would naturally be.

the roads and trees give us some vague idea of scale, yet there either is no river, or something is amiss in these pics.

Interesting that there appear to be traces of a road/pathway trans-secting the "pyramid" - top corner to bottom corner in the picture.

Probably belongs to some ancient Smurf civilization.
