Moray is an archeological site in the Sacred Valley of Peru that looks something like a crop circle.  From the top ring to the bottom ring there is a temperature difference of roughly 15 degrees Celsius.  It is speculated that the Incans used the site to experiment with different types of agriculture at different elevations.  For example, potatoes would be planted at a higher ring because they only grow at a higher elevation while corn grows at the lowest (with fava beans somewhere in the middle).  Our own experiment was to see how quickly we could descend to the bottom of the circles, navigating a complex series of steps protruding from the ancient stones.  Click below and enjoy our journey with us — in glorious stop motion.
