Dinosaur Wall, Cal Orko, Sucre, Bolivia

The fascinating 70-degree rockface is a rather new discovery, found by Bolivian workers, in 1994. It stretches 1.5 kilometers in length and it’s 150 meters tall. Compared to other dinosaur track sites, on any other continent, Cal Orko is by far the biggest and most important.
Unfortunately, Cal Orko is in constant danger of crumbling and Bolivian authorities spend $30 million every year, to keep it in place. With all their efforts, part of the Dinosaur Wall has crumbled at the beginning of February, and with it about 300 footprints have been lost.
