Penedo do Pé Calvo
Due to their extension and nature, the crags of Monsanto represent a vast set of rocky formations created by various types of erosion in a long, slow weathering process of the granite they are made up of. The long presence of man in these places, living in close contact with these immense rock formations, led to their being used wisely, or in other cases, being given names and meanings as a simple sign of resignation to their presence. There are over two dozen crags and outcroppings with their own place name, as is the case here. We are talking about a gigantic cliff with a cleft, set on a horizontal rocky base with multiple fractures, where the mechanical fracturing is clearly seen, which serve as a good example of physical weathering.
