Arequipa (département)
Arequipa (Ariqipa; Ariqipa) is a department and region in southwestern Peru. It is the sixth largest department in Peru, after Puno, Cuzco, Madre de Dios, Ucayali, and Loreto, its sixth most populous department, and its eleventh least densely populated department. It is bordered by the departments of Ica, Ayacucho, Apurímac and Cusco in the north, the Department of Puno in the east, the Department of Moquegua in the south, and the Pacific Ocean in the west. Its capital, also called Arequipa, is Peru's second-largest city. This department has a rough topography, which is characterised by heavy layers of volcanic lava covering large areas of its inter-Andean sector. It has deep canyons such as the ones formed by the Ocoña and Majes rivers. Plateaus range in height from medium, such as La Joya, and high-altitude ones such the Arrieros Pampa and those located in the zones of Chivay, Huambo and Pichucolla. Volcanic cones, such as Misti, Chachani, Ampato, Mismi, Solimana and Coropuna, emerge above the plateaus and attract snowfall. In contrast with these heights, there are deep canyons, including Majes, Colca, Sihuas and Ocoña, where important aspects of the ecological evolution of this zone can be clearly observed. Along the coast, small plateaus and dunes represent characteristics of the desert of Arequipa, such as the ones located in the Majes, Sihuas and La Joya plains. These are particularly beautiful and developed. From a hydrographic point of view, the rivers draining its territory belong mainly to the Pacific watershed. Some rivers belong to the Amazon hydrographic system. Some of the region's main rivers are: Ocoña, Yauca, Camaná and Quilca. The starting point of the Amazon River is located in the Arequipa region . The Highest Mountains of Arequipa are: Coropuna 6,425 mamsl, Ampato Range. Ampato 6,288 mamsl, Ampato Range. Solimana 6,093 mamsl, Ampato Range. Chachani 6,057 mamsl, Volcanic Range. Hualca Hualca 6,025 mamsl, Ampato Range. Sabancaya 5,976 mamsl, Ampato Range. Misti 5,822 mamsl, Volcanic Range.
