Giant columns of more than 40 m. height geometric shape of a singular beauty, unique in the world, better known as PRISM basaltic O BASALTO PRISMATICO derived from igneous rock outcrop. The origin of these formations, dates back to rapid cooling of lava during a spill million years ago, which was poured at the bottom of the canyon. Each column is between 80 cm. in diameter and several meters high accommodated vertically, five or six sides, clearly defined joints between them, highlighting the color from gray to black of these geometric monuments. A geological quirk that gives us an impressive show of geophysics magic of nature, such that look like they were carved with engineering support of Man it off festooned and nuanced torrents of water that form whimsical waterfalls that create a slight breeze, which turn sunlight with a countless microarcoiris becoming magical stay at this place. Baron Alexander Von Humboldt was so impressed by such beauty, that he pencils in 1803 and now exhibited in a museum in London.
