Colca Canyon
In May 1981, the Polish Canoandes rafting expedition, led by Andrzej Pietowski, made the first descent of the river below Cabanaconde and proclaimed the possibility of its being the world's deepest canyon. It was so recognized by the Guinness Book of Records in 1984, and a National Geographic article in January 1993 repeated the claim. A joint Polish-Peruvian "Cañon del Colca 2005" expedition verified the altitudes of the river and the surrounding heights via GPS.
