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 Puerto Maldonado
Puerto Maldonado is a city in southeastern Peru in the Amazon rainforest 55 kilometres (34 mi) west of the Bolivian border; located at the confluence of the Tambopata and Madre de Dios rivers, the latter of which joins the Madeira River as a tributary of the Amazon. It is the capital of the Madre de Dios Region.
Nearby are the Manú National Park, Tambopata National Reserve, and Bahuaja-Sonene National Park, which have been established to protect natural resources. These are some of the most pristine primary rain forests in the world. They include several oxbow lakes and clay licks, where hundreds of birds, including macaws, feed on clay.
Puerto Maldonado is in the tropical Amazon Basin. The climate is hot and humid at all times. The average annual temperature is 26 °C (79 °F) with the months of August and September being the hottest. Annual rainfall exceeds 1,000 millimetres (3.3 ft). The wet season is from October to April. The main part of the town is located on a slightly elevated area that does not normally flood in the wet season. Road travel often becomes impossible during this time. A low season occurs between June and August.
The chief industries in Puerto Maldonado are logging, artisanal small-scale gold mining,[8] Brazil nut collecting, boat building and eco-tourism. The area is virtually logged out; only one mill remains. The area was exploited for rubber in the late 19th-century and early 20th-century rubber boom, but South American production was undercut by the industry developed in southeast Asia. Rubber collection has long since ended.
At least 30,000 gold miners are active in the region around Puerto Maldonado.[8] Legislation in the European Union in the 21st century resulted in putting hundreds of Brazil nut collectors out of work, together with the crew of the associated local factory, as it raised tariffs against the product.
Tourism and related boat construction are currently the major sources of income in the economy. There are several tourist eco-lodges around Puerto Maldonado and in the reserves.
