The Nazca lines look like they are painted on or something. They are not. My understanding is that the plateau is covered with a fine layer of dust because it basically never rains there and for some reason there is no wind I guess. Anyway, the figures were created by indians scraping away the dust in a strategic way. Now walk in with hiking boots and you leave more or less permanent footprints in that same dust.
Exactly. From what I understand the lines are very shallow trenches.
“Anyway, the figures were created by indians scraping away the dust in a strategic way.”
Rocks, not dust, were removed.
