Pedra da Gávea is a mountain in Tijuca Forest, Rio de Janeiro, Brazil. Differential weathering on one side of the rock has created what is described as a stylized human face. Markings on another face of the rock have been described as an inscription. Some individuals, such as Bernardo de Azevedo da Silva Ramos, have advanced the position that the inscription is of Phoenician origin and possibly proof of pre-Columbian contact from Old World cultures. Alternative theories proposed include that the rock was the site of a Viking colony or that it is connected with suspected UFO activity. Geologists and scientists are nearly in agreement that the "inscription" is the result of erosion and that the "face" is a product of pareidolia. No credible evidence has ever been collected that backs up the idea that Pedra da Gávea was discovered by Phoenicians or any other civilization. Furthermore, the consensus of archaeologists and scholars in Brazil is that the mountain should not be viewed as an archaeological site, and hypotheses that regard it as such are fringe theories.
