Geoglyphs in the Amazon
"Geoglyphs" are shapes or designs made in the earth by digging and mounding that have no obvious structural purpose; the most famous example is the Nazca lines. A road crew working in the Amazon recently encountered several, some of which are pictured above. Everywhere people look in the Amazon they find more evidence of civilizations that disappeared 400 years ago.
