On the flat surface of this strange outcropping, various shallow depressions can be seen, which in reality number 14, as there is an isolated one on the top of the adjoining rock. These depressions are frequently thought to be man made. Some authors even associate them with an ancestral sanctuary. And popular imagination created a legend to explain the enigmatic rock formation, attributing its origin to the charity of a noblewoman who served soup to the poor here. However, there is apparently a more credible natural explanation for the depressions: their origin as magma formed irregulaties in the granite; later, the exposed rock underwent differentiated processes of erosion, being worn away more rapidly in the areas where the depressions are found, a geological process known as chemical weathering.
