Cordillera Vilcanota
The Cordillera Vilcanota (Spanish cordillera: "mountain range", Aymara Willkan Uta or Willkanuta: "house of the sun") is a mountain range located in Peru southeast of Cusco, on the boundary between the regions of Cusco and Puno. It extends between 13°39' and 14°29'S and 70°31' and 71°20'W for about 80 km. It includes 469 glaciers. To the east the rivers San Gabán and Azángaro are the natural boundary which separates it from the Carabaya range. The La Raya range near the La Raya pass is sometimes included or listed separately. Toponyms Most of the names in the range originate from Quechua and Aymara. They used to be spelled according to a mainly Spanish-based orthography which is incompatible with the normalized spellings of these languages and Law 29735 which regulates the 'use, preservation, development, recovery, promotion and diffusion of the originary languages of Peru'. According to Article 20 of Decreto Supremo No 004-2016-MC (Supreme Decree) which approves the Regulations to Law 29735, published in the official newspaper El Peruano on July 22, 2016, adequate spellings of the toponyms in the normalized alphabets of the indigenous languages must progressively be proposed with the aim of standardizing the namings used by the IGN.
