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 Yurimaguas
Yurimaguas is a thriving port town in the Loreto Region of the northeastern Peruvian Amazon. Historically associated with Maynas (Pais de los Maynas), the culturally diverse town is affectionately known as the "Pearl of the Huallaga" (Perla del Huallaga). Yurimaguas is located at the confluence of the majestic Huallaga and Paranapura Rivers in the steamy rainforests of northeastern Peru. It is the capital of both Alto Amazonas Province and Yurimaguas District, and had a population estimated at about 64,000 inhabitants (2002).
With a long and illustrious history, Yurimaguas is a tourist destination, especially during the August 15 annual Catholic festival of the Assumption. Long dominated by the presence of the Church, the town is home to the Apostolic Vicariate of Yurimaguas, Loreto Region. Visited in 1855 by the famed botanist Richard Spruce[1], Yurimaguas remains an important commercial center for subsistence and market oriented farmers or ribereños (who cultivate sugar cane, bananas, cotton, tobacco, manioc and other comestible produce) and fishermen.
Yurimaguas is notable for being the last urban center in Loreto connected by highway with the rest of Peru: a recently paved road links Yurimaguas with Tarapoto and Moyobamba, located in the tropical Andes (high-jungle), or as it is known in the vernacular, the montaña. While the Moisés Benzaquen Rengifo Airport was first established in Yurimaguas in 1937, it is now barely functioning (the collapse of the Peruvian airline Aero Continente left only two airlines serving the airport). For the majority of the populace, transit is dominated by river travel. In the ports of Yurimaguas trade is in tropical forest produce, particularly hardwoods, petroleum, contraband, and goods (licit and otherwise) from the Andean highlands or Pacific Coast sent down-river to Iquitos and beyond (the Port Authority of Yurimaguas, ENAPU is in charge of the International Puerto de Yurimaguas, Peru). Yurimaguas boasts a magnificent Cathedral built by the Passionist Order, and modeled after the Cathedral in Burgos, Spain.
