Lake Junín

                Lake Junín (Lago Junín, Chinchaycocha) is the largest lake entirely within Peru. Even though Lake Titicaca has a much larger area, its eastern half is located on Bolivian territory. It is located at approximately 4,082 metres (13,392 ft) above sea level, and it had a surface of 529.88 square kilometres (204.59 sq mi).
                Most of the lake is located in the Junín Province of the Junín Region, its northwestern tip belongs to the Pasco Province, which is in the Pasco Region. The primary outflows are Upamayo and Mantaro River. Lake Junín has two endemic birds: The critically endangered Junín Flightless Grebe (Podiceps taczanowskii) and the endangered Junín Rail (Laterallus tuerosi).

Amazon river

             Amazon river (Amazonas) is the second longest river in the world (6,400 km (4,000 mi)) and by far the largest by waterflow with an average discharge greater than the next seven largest rivers combined (not including Madeira and Rio Negro, which are tributaries of the Amazon).
             The Amazon, which has the largest drainage basin in the world, about 7,050,000 square kilometres (2,720,000 sq mi), accounts for approximately one-fifth of the world's total river flow. The width of the Amazon varies between 1.6 and 10 kilometres (1.0 and 6.2 mi) at low stage, but expands during the wet season to 48 kilometres (30 mi) or more. The river enters the Atlantic Ocean in a broad estuary about 240 kilometres (150 mi) wide. The mouth of the main stem is 80 kilometres (50 mi).
             The Amazon has over 1,100 tributaries, 17 of which are over 1,500 kilometres (930 mi) long. Some of the more notable ones are: Madeira, Purus, Yapura, Tocantins, Araguaia, Juruá, Rio Negro, Tapajós, Xingu, Ucayali River, Guaporé, Içá (Putumayo), Marañón, Teles Pires. It is crossing the following cities: Iquitos (Peru), Leticia (Colombia), Manaus (Brazil), Santarém and Belém do Pará (Brazil), Macapa (Brazil).

Titicaca lake

            Lake Titicaca is a lake in the Andes on the border of Peru and Bolivia. It had a surface of 8,372 km² (3,232 sq mi). By volume of water, it is also the largest lake in South America. It is often called the highest navigable lake in the world, although this refers to navigation by "large" boats, generally considered to mean commercial craft. Five major river systems feed into Lake Titicaca. In order of their relative flow volumes these are Ramis, Coata, Ilave, Huancané, and Suchez.

        The lake had more than 40 islands, the biggest beeing Uros, Amantani, Taquile, Isla del Sol, Isla de la Luna, and Suriqui.

Huascaran Mountain

            Huascarán or Nevado Huascarán is a mountain in the Peruvian province of Yungay, situated in the Cordillera Blanca range of the Western Andes. The highest southern summit of Huascarán (Huascarán Sur) is the highest point in Peru, and all the Earth's Tropics. 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. Huascarán is the fourth highest mountain in the Western Hemisphere after Aconcagua, Ojos del Salado, and Monte Pissis. It has an elevation of 6,768 metres (22,205 ft).The core of Nevada Huascarán, like much of the Cordillera Blanca, are Tertiary granites.
             On 31 May 1970, the Ancash earthquake caused a substantial part of the north side of the mountain to collapse. The avalanche mass, an estimated 80 million cubic feet of ice, mud and rock was about half a mile wide and a mile long. It advanced about 11 miles (18 km) at an average speed of 280 to 335 km per hour burying the towns of Yungay and Ranrahirca under ice and rock, killing more than 20,000 people.
