In 1981 the first Polish expedition, based on topographic maps of low accuracy, considered that the Colca Canyon reached a depth of 3250m. This information was used for many years.
But in 2005, an expedition led by Polish researcher Andrew Pietowski performed several measurements using modern high-precision devices, including a "Global Positioning System” (GPS), obtaining accurate data on the height of this natural wonder.
And it was on the 24th of August, 2005, in the city of Arequipa, during a press conference, that they revealed that in the territory of Canco of the district of Huambo the profundity of the Colca Canyon reached 4160m on the north side and 3600 m on the south side.

This makes the Colca Canyon the deepest Canyon of America and approximately more than twice as deep as the Grand Canyon.
