The Geoglyphs of Teohuanaco

Although this appears to be an amazing discovery, I can't help but be a little bit sceptical... There seems to be no on-the-ground verification of these lines and shapes, and for them not to be discovered until this year seems strange to me.

"This satellite image (above) is a portion of the Andean foothills surrounding Lake Titicaca in Bolivia, South America. It is a small sample of a vast network of patterns that surround the lake and extend for more than one hundred miles south into the Bolivian desert. The patterns display geometric repetition and intelligent design. There are interlocking rectangular cells and mounds, perfectly straight lines and tree like arrays that are uncharacteristic with natural erosion. These cover every topographical feature of the high plateau surrounding the lake, over flood plains, hills, cliffs and mountains. Although these geoglyphs are remarkable in their obvious strangeness, what is more astounding is that they have remained in obscurity until now."

I'd love to see these in person, talk to the locals... Until then, I'll consider that there's either an easy answer, or they'll be harder to crack than the Nazca Lines.
