I can’t see that they did any damage. They broke the rules, and when they did that, they were laid bare. Serves them right I guess, what were they thinking?
You can’t see the damage in the photo, but there is a LOT of it. I saw a photo imaged to bring out the damage, and it will take countless hours to repair. You could go read about it, but you don’t seem to appreciate preservation of a national treasure of archeology or ancient art itself very much.
Mr. Mercat and I have been there. The desert in Peru is very strange and fragile. It never rains there but it’s always foggy. The few plants live by pulling moisture from the air. The surface in Nazca has been undisturbed except for the lines forever. The lines are simply where the ancients “scarred” the ground. It could not have survived in any other place on earth.
