Found something in Goggle map in Gulf of CA

Steve, my question is how did they get it so straight and how long a rope did they need to get it that dead on. Those lines goes on for a mile or more?

Why aren't they anywhere else around the area or even further away on other parts of the sea bed?

I'm going to need about tree fiddy

I'd swim out there with a snorkel and googles and take a look.

Assuming you're talking about the Nazca lines.

How Were the Lines Made?

Fortunately one thing that most scientists can agree upon is how the lines were made. At first the enormity and preciseness of the lines seems to point to a remarkable feat of engineering. Many of the drawings must also be viewed arially to see them in their entirety, and thus it was thought that it would have required an airborn observer to aid the artists in creating the precise figures and proportions we see today. However, according to Dr. Persis B. Clarkson, an archaeologist and geoglyph expert at the University of Winnipeg “ It was not a difficult technology.all you need is the will.” It would have just taken careful and diligent attention to sight the lines. To prove this, a group of 10 Earthwatch volunteers helped an astronomer and anthropologist, Anthony Aveni, in a study of the Nazca lines. In just and hour and a half, without a printed plan, they created a straight line winding into a spiral 35 meters long and one meter wide. Splitting into groups, each one performed a different task, and the result was, according to Aveni, a figure as accurate as any Nazca drawing measured with a surveyor’s instrument. It is fairly conclusive that it was not necessary for the Nazca to have possessed great mathematical or engineering skills to create the figures or lines in the desert. It was possible simply by people working together with their eyes and hands. So there is one of the mysteries cleared up.

There will always be the naysayers, and the alien theorist’s, but it is fair to point out other possible means of these lines creation. Because of the drawings being so large, and as previously mentioned, only fully viewable from the air, it was suspected that perhaps the Nazca were capable of flight. Pottery found in the area depicted images that could have been kites, or baloons. At the end of many of the lines were found wide circular pits containing charred rocks that could have been a launching site for a hot air baloon. A big if, but one some felt was worth testing. Bill Spohrer, an American living in Peru, and Jim Woodman, a member of the International Explorers Society, recreated a baloon using materials they thought would have been available to the Nazcans. Using only the heat generated from the ‘burn pit’ to lift off, the balloon flew a total of 14 minutes, on three different tries. Although a fascinating possibility, there is no evidence that the Nazcan’s actually could have or did fly. It still remains much more likely that they lines were created only from those on the ground.
