After 3 straight hours of the Rugrats this morning, I was desperate for something different. I told Willow we were going to watch one of my shows (i.e., documentaries) and she protested. I looked through all the documentaries I had stored up on the DVR, and for one reason (Samurai swords? Too gory.) or another (Caligula... oh, let's wait about 15 years before she needs to know any of that) I discarded them. Then, I found one that was interesting enough for me and palatable for her and it was about the Nasca geoglyphs in southern Peru ( http://www.unmuseum.org/nazca.htm )
Day 4: The Nasca lines were not gouged or carved into the earth. They were created by simply moving the volcanic rock on top of the yellow clay off to the sides.
Archeological teams have proven that even some of the larger geoglyphs could be created in 48 hours even with the tools available to the Nasca people. And it is interesting why the lines have lasted so long - the heat of the day warms the clay and creates a heated barrier against the wind - so the stones don't mess up the lines.
