Information about the city Cerro de Pasco
Cerro de Pasco (population 70,000) is a city in central Peru, located at the top of the Andean mountains. It is the capital of the Pasco region, and an important mining center. At 4,330 metres (14,210 ft) elevation, it is one of the highest cities in the world, and the highest or the second highest city with over 50,000 inhabitants, with elevation reaching up to 4,380 m in the Yanacancha area. It is connected by road and by rail to the capital Lima, as far as 300 km.
Cerro de Pasco became one of the world's richest silver producing areas after silver was discovered there in 1630.[2] It is still an active mining center. The Spanish mined the rich Cerro de Pasco silver-bearing oxide ore deposits since colonial times. Sulfide minerals are more common in the Atacocha district however.
Francisco Uville arranged for steam engines made by Richard Trevithick of Cornwall, England, to be installed in Cerro de Pasco in 1816 to pump water from the mines and allow lower levels to be reached. However, fighting in the Peruvian War of Independence brought production to a halt from 1820 to 1825. Three major mines in the area include the Machcan, Atacocha, and Milpo. SIlver ore occurs in hydrothermal veins or as sulfides and clay minerals replacing the Jurassic Pucara limestone. Porphyry dacite stocks are found intruded near the Atacocha and Milpo mines along the Atacocha Fault. Compania Minera Atacocha started operations at the Atacocha Mine in 1936. Ore minerals include galena and sphalerite.
At 4,330 metres (14,210 ft) above sea level, Cerro de Pasco has an (E) Alpine Climate (the average temperature of the warmest month is lower than 10 °C (50 °F)), the city is one of the largest in the world with this classification. Temperatures are too cold to allow for tree growth in and around the city giving the countryside its barren appearance. Cerro de Pasco has humid summers, dry winters and chilly to cold temperatures throughout the year. Snowfall occurs annually.
Information about the city La Libertad
La Libertad is a region in northwestern Peru. Formerly it was known as the Department of La Libertad (Departamento de La Libertad). It is bordered by the Lambayeque, Cajamarca and Amazonas regions on the north, the San Martín Region on the east, the Ancash and Huánuco regions on the south and the Pacific Ocean on the west. Its capital is Trujillo, which is the nation's third biggest city. The region's main port is Salaverry, one of Peru's largest ports. The name of the region is Spanish for "freedom" or "liberty"; it was named in honor of the Intendencia of Trujillo's proclaiming independence from Spain in 1820 and fighting for that.
During the viceroyalty of Peru, the La Libertad region, together with the present-day regions of Lambayeque, Piura and Tumbes regions in Peru, and Guayaquil and El Oro Province in Ecuador, were all within the jurisdiction of the Intendencía de Trujillo. These were included in the domain of the city of Trujillo; together they comprised the Departamento de Trujillo of the viceroyalty.
After the Intendencía joined the emancipation cause and was the first to gain independence from Spain, in 1825 the Congress of the Peruvian republic changed the name to Departmento de la Libertad. Since the late 20th century, Peru has decentralized its government. All former Departments in Peru are now called Regions; their governors are elected, and they have more independent authority in decisionmaking.
La Libertad is the only Peruvian region that includes all three natural regions of the nation: coast, Sierra (highlands), and selva (rainforest).
Trujillo, the capital, has a strategic location, near where the Andes come closest to the coast. Seen from Trujillo, the Andes appears as a row of low-elevation hills. The Andean Plateau increases altitude sharply to the east, in the provinces of Otuzco and Santiago de Chuco. These two provinces comprise the Pacific hydrographic watershed, which give rise to the Moche and Virú rivers, to the south, and Chicama River to the north. Pacasmayo Province, located more to the north, is along the coast. To the east, Sánchez Carrión Province waterways drain into the Amazon River and thus belong to the Atlantic Ocean watershed.
