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 Mollendo
Mollendo is a town bordering the Pacific Ocean in southern Peru. It is located in the Arequipa Region and is the capital of both the Islay Province and the Mollendo District. Mollendo was the main port in the Peruvian southern coast until Matarani was developed about 50 years ago; the port of Mollendo only serves fishermen for the local economy currently and all the commercial shipping is done through Matarani 12 kilometers north; the old port is in ruins. From about 1830 to 1880 it was important in the Guano trade.
The railroad used to run a passenger train daily, but a good highway connects Mollendo to the Panamerican Highway now and the train now only runs the summer express that goes down from Arequipa on Saturday and returns on Sunday; the beach is the main attraction, even though it is visited by the Humboldt Current that brings cold water from Antarctica.In the summer months, which run from January to March, the population more than doubles as people from the largest city in the region Arequipa use Mollendo and its beaches as a vacation spot, especially on weekends. Mollendo exports wool and has industries producing cement, textiles, canned fish, and cheese. It is also a popular beach resort. The Auxiliary Ship BAP Mollendo (ATC-131) of the Peruvian Navy is named after the town.
About 1300, the legendary Inca Mayta Cápac, puts the regions of Arequipa and Moquegua under the control of the Inca empire. Sixty three years later, and according to Garcilaso de la Vega, the Inca Cápac Yupanqui, following traditional customs of the Inca Empire, selected four generals from his major staff and entrusted them the command of approximately twenty thousand soldiers (or Tuqui Titos) for the coast region conquest project.
Cápac Yupanqui's son, Sinchi Rocca, conquered all of Arequipa and Moquegua coast area. From this event and ahead, Tambo is a main protagonist into the region history, due their geographical position and serving as weapons and food supply depot. Inca Yáhuar Huácac, successor of Inca Cápac Yupanqui, established his supply depots and headquarters in this valley, to march into Atacama (north Chilean region) direction to expand the territory of the Inca Empire.
During the War of the Pacific Mollendo was invaded by Chilean forces under the command of Colonel Orozimbo Barbosa. The main idea of this army (transported by the Chilean Navy) was to wreak havoc on Southern Peru, so as to force the process of negotiations for peace between Peru and Chile. The invasion forces consisted of the 3rd Chilean Line Infantry Regiment, The Chilean Marines, One brigade of Chilean Sappers, and 30 Horse Cavalry. The defenses of Mollendo consisted of two small forts with no cannon ( which were days earlier transported to Arequipa) defended by 100 soldiers. The first to disembark were the Chilean Marines, who took the town without a struggle. The rest (Main Body) of the expedition landed on or near Islay, without opposition. On March 9, 1880, the Main Body of the expedition entered Mollendo. Colonel Barbosa with 500 soldiers left Mollendo towards Mejia in search of the defenders, leaving the 3rd Chilean Line Infantry in charge of the town, looting of homes quickly began. Colonel Barbosa arrived in Mejia, destroying the locomotives and railtracks to prevent reinforcements arriving from Arequipa via rail. Colonel Barbosa surprised the defenders at Ensenada, taking 20 prisoners. Upon his return to Mollendo, he learned of the sacking of the town, punishing some members of his command. This resulted in some desertions.
