@ Sergey kirikov Version corrals or traps for livestock does not pass in any way. First number-tens of thousands of structures (rather complex, because many prepared base). Costs are not comparable with the benefit. Secondly. It is lifeless. Not as many animals, there is no food or water. No people who would all this built. Most geoglyphs form does not allow you to use them as traps, plus their height 0.5-1 metre. Detain anyone they cannot. The age of the geoglyphs-several thousand years, and they were built when the Sugar has already been desert. Many of the geoglyphs are clearly meaningful form-image, such as UFOs.
