Huascarán (Spanish pronunciation: [waskaˈɾan]) or Nevado Huascarán is a mountain in the Peruvian province of Yungay (Ancash Departament), situated in the Cordillera Blanca range of the western Andes. The highest southern summit of Huascarán (Huascarán Sur) is the highest point in Peru, northern part of Andes (north of Lake Titicaca) and in all of the Earth's Tropics. Huascarán is the fourth highest mountain in the Western Hemisphere after Aconcagua, Ojos del Salado, and Monte Pissis. The mountain was named after Huáscar, a 16th-century Inca emperor who was the Sapa Inca of the Inca empire.The mountain has two distinct summits, the higher being the south one (Huascarán Sur) with an elevation of 6,768 metres (22,205 ft). The north summit (Huascarán Norte) has an elevation of 6,654 metres (21,831 ft). Both summits are separated by a saddle (called 'Garganta'). The core of Huascarán, like much of the Cordillera Blanca, consists of Cenozoic era granite.Huascarán gives its name to Huascarán National Park which surrounds it, and is a popular location for trekking and mountaineering. The Huascarán summit is one of the points on the Earth's surface farthest from the Earth's center, closely behind the farthest point, Chimborazo in Ecuador.The summit of Huascarán is the place on Earth with the smallest gravitational force.
