Chapada is understood as a type of geological formation similar of a canyon. Basically, it is an elevated region, flat top, called plateau, and whose edge consists of walls caused by sedimentary erosion. Several laminations are perceived trrough the walls, revealing the diverse changes undergone by the region during the transformation of the terrestrial globe. These stratifications tell the history of the region, revealing its various phases like desert, ocean bottom, volcanic eruptions, forests, etc. and even revealing the ancient fauna and flora through fossils.
Brazil has 3 large and distinct chapadas, exuberant in nature and excellent points of ecotourism, which inspired William Marques in his works. Learn a little of each one in the links offered by William Marques. There you can find tips and a gallery of photos taken by the author himself.
