[2] The name comes from perceived resemblance of the vertical rock formations created by erosion to the tubes of organs used in Portuguese churches at the time.
[3] The Dedo de Deus (God's Finger) and Escalavrado, at 1,692 metres (5,551 ft) and 1,490 metres (4,890 ft) and the nearby peaks with steep rock walls are dramatic features that can be seen on a clear day from Rio de Janeiro, which is 50 kilometres (31 mi) distant.
[1] A north west fracture is exposed at the plateau's rock surfaces, which defines the direction of the ridges and valleys along the escarpment.
[5] In November 1981 a period of intense rain triggered hundreds of shallow landslides and flows of debris that blocked the BR-116 highway and killed about 20 people.
[1] The ridge containing the God's Finger and other towers is unusual in being sustained by a thick dike of Cambrian granite that is more resistant to erosion than the surrounding Neoproterozoic orthogneisses.
