Do you watch what is beneath your feet when you walk on a road?
You better start doing the same because what happened in Nazca Desert in Southen Peru was an example of the same negligence. These lines were beneath the feet of the archeologists, but they still weren’t able to locate it until the early 1900’s because you won’t be able to spot them until you’re just above them. There have been many explanations for the same, but there is no concrete explanation for the same.
