Geoglyphs

Thinking of BIG reminded me of Aussie artist Andrew Rogers, who has been engaged in the largest contemporary land art project in the world: Rhythms of Life. With the help of over 6,700 people, he's built a chain of 47 massive stone sculptures - he calls them geoglyphs - in 13 countries across seven continents. This is one of his smaller efforts Ancient Language in the Atacama Desert, Chile (2004) a mere 262ft long and nearly 10ft high. Looks like a dead dragon to me. If you're trekking through the Atacama Desert, keep an eye open for it. But be warned; that is the driest desert in the world.
