Mapimí, Durango
Mapimí () is a city and municipal seat of the Mapimí Municipality in the Mexican state of Durango. As of 2015, the town of Mapimí had a population of 5,623. The Ojuela Mine, about southeast of Mapimí, is a famous locality for mineral specimens, especially adamite. History When the Spanish first arrived in the Mapimí area in the late 16th century, nomadic and semi-nomadic Native Americans such as the Tepehuan, Tobosos, and Cocoyones were the inhabitants.Griffen, William B. (1969), ''Culture Change and Shifting Populations in Central Northern Mexico,'' Tucson: University of Arizona Press, pp 75-76. Mapimi was founded on July 25, 1598 by Agustin de Espinoza, a Jesuit priest, and Captain Antón de Zapata, a soldier. The settlement was named Santiago de Mapimí. The name derives from the Cocoyones who called the area "Mapeme," meaning "high mountain." As with most early settlements in Northern Mexico, the abundant minerals in the area were the attraction for settlers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endorheic Basin
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔνδον ''éndon'' 'with ...

Populated Places In Durango
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with in ...

Radio Silence
In telecommunications, radio silence or Emissions Control (EMCON) is a status in which all fixed or mobile radio stations in an area are asked to stop transmitting for safety or security reasons. The term "radio station" may include anything capable of transmitting a radio signal. A single ship, aircraft, spacecraft, or group of them may also maintain radio silence. Amateur radio Wilderness Protocol The Wilderness Protocol recommends that those stations able to do so should monitor the primary (and secondary, if possible) frequency every three hours starting at 7 AM, local time, for 5 minutes starting at the top of every hour, or even continuously. The Wilderness Protocol is now included in both the ARRL ARES Field Resources Manual and the ARES Emergency Resources Manual. Per the manual, the protocol is: The Wilderness protocol (see page 101, August 1995 QST) calls for hams in the wilderness to announce their presence on, and to monitor, the national calling frequencies for ...

Recuerdo Del Puente De Ojuela - Gold Mine - 1892 - Near Torreon, Mexico 008-800X600
''Memory, the Heart'', a 1937 painting by Frida Kahlo, depicts the pain and anguish Kahlo experienced during and after an affair between her husband, artist Diego Rivera, and her sister, Cristina Kahlo. The painting is sometimes known by the title ''Recuerdo'' (''Memory''). The oil-on-metal work measures 40 x 28 cm, and is held in the collection of Michel Petitjean in Paris, France. Description Kahlo portrays herself standing on a beach by the water's edge, one foot on the sand and one in the sea, looking towards the viewer with an expressionless face covered in tears. A metal rod goes through a large empty space in her chest. The rod has an image of Cupid at each end, shown as if riding a seesaw. Frida's heart is represented by a large bleeding mutilated organ lying outside her body. The blood from the heart seeps into the sand and flows into the sea. Two dresses, one a schoolgirl dress, the other her traditional Tehuantepec-style costume, hang near Frida; not empty, the ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mapimí Biosphere Reserve
The Mapimí Biosphere Reserve ( es, Reserva de la Biósfera de Mapimí) (established 1977) is a UNESCO Biosphere Reserve located in the state of Durango in northern Mexico. It is one of three biosphere reserves representing the Chihuahuan Desert (along with Big Bend Biosphere Reserve and National Park in western Texas and Jornada Biosphere Reserve in New Mexico). The reserve is situated between the Neotropical and Nearctic biogeographic realms, in the Bolsón de Mapimí above sea level. It contains three core areas in the ''Sierra de la Campana'', the ''Laguna de las Palomas'', a salt lagoon, and a desert habitat called ''Dunas de la Soledad''. It comprises fragile warm desert and semi-desert ecosystems and rich, highly adapted but vulnerable plant systems, mainly xerophytic matorral scrub, and animal species such as the puma (''Puma concolor''), mule deer (''Odocoileus hemionus''), sandhill crane (''Grus canadensis'') and the kit fox or ''zorrita del desiert'' (''Vulpes mac ...

Mapimí Silent Zone
The Mapimí Silent Zone ( es, La Zona del Silencio) is the popular name for a desert patch near the Bolsón de Mapimí in Durango, Mexico, overlapping the Mapimí Biosphere Reserve. It is the subject of an urban legend that claims it is an area where radio signals and any type of communications cannot be received. History and legends The area was once an ancient seabed in the Tethys Ocean, which left marine fossils and large salt deposits which are mined today. In July 1970, an Athena RTV test rocket launched from the Green River Launch Complex in Utah towards the White Sands Missile Range in New Mexico lost control and fell in the Mapimí Desert region. When the rocket went off course, it was carrying two small containers of cobalt 57, an isotope used in " salted bombs" to intentionally contaminate large areas of land. As part of the cleanup effort, hundreds of tons of soil were removed from the impact site. As a result of the US Air Force recovery operation, a number of ...

Ojuela Bridge
The Ojuela Bridge or the Mapimi Bridge (Puente de Ojuela, Spanish name) is a suspension bridge located in Mapimí, in the Mexican state of Durango, at the site of the Ojuela Goldmine. The Ojuela Bridge was designed by Wilhelm Hildenbrand McCullough, David "Brave Companions - Portraits in History", p.122 and built by the firm of John A. Roebling John Augustus Roebling (born Johann August Röbling; June 12, 1806 – July 22, 1869) was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as ... Sons Company, New York. Completed in 1898 the bridge was restored as a tourist attraction in 1991. It has a main span of 271.5 metres and the distance between the pylons is 315.5 metres. Currently this bridge is only used for pedestrians. Two plaques were posted on the bridge to commemorate 100 years since its setting it up.

Endorheic Lake
An endorheic lake (also called a sink lake or terminal lake) is a collection of water within an endorheic basin, or sink, with no evident outlet. Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation. These lakes can be used as indicators of anthropogenic change, such as irrigation or climate change, in the areas surrounding them. Lakes with subsurface drainage are considered cryptorheic. Components of endorheic lakes The two main ways that endorheic lakes accumulate water are through river flow into the lake (discharge) and precipitation falling into the lake. The collected water of the lake, instead of discharging, can only be lost due to either evapotranspiration or percolation (water sinking underground, e.g., to become groundwater in an aquifer). Because of this lack of an outlet, endorheic lakes are mostly salt water rather than fresh water. The salinity in the lake gradually builds up through years as wate ...
