The Sierra de la Ventana (also Sierras de Ventania) is a mountain range in Buenos Aires Province, and one of only two located within the Pampas ecosystem.
Bounded approximately by the Laguna del Monte, Guaminí at its northwestern end and the Atlantic Ocean to its southwest, the Sierra de la Ventana lies on a precambrian base formed around 2.2 billion years ago, and is interspersed with granite, granodiorite, and amphibole deposits.
Characterized by its escarpments, this orography prevented the deposit of significant amounts of loess, and made the area the least propitious for agriculture within the Pampas; sunflower fields are common along the foot of the range. Its soils feature an A-AC-C horizonation, not unlike those found along the Appalachian range. Its climate is somewhat colder and drier than that prevailing in the surrounding Humid Pampas, though the range receives more rainfall than the Semi-arid Pampas located to the west. Sizable extensions of lacebark pines grow along the range, possibly introduced from Asia.[ citation needed ]
Peppered by caves and grottoes, the range is relatively modest in height and extension, and exceeds 1000 m (3280 ft) at only six points. These peaks are:
British naturalist Charles Darwin described his ascent of the Sierra de la Ventana range in the sixth chapter of his work The Voyage of the Beagle. [1] The region's breezes and mild climate made it a tourist attraction beginning in the early part of the 20th century, and its principal early promoter was Ernesto Tornquist, a prominent rancher, banker and developer. The extension of the Buenos Aires Great Southern Railway past the area led to the construction of the Club Hotel de la Ventana, a luxury casino and hotel, and the outpost of Villa Ventana, a resort community developed by the Sociedad de Compañías de Tierras y Hoteles de Sierra de la Ventana. The hotel closed after President Hipólito Yrigoyen's 1918 edict banning gambling, and development of the area's tourism resources remained below their potential in subsequent decades. [2]
Buenos Aires, officially the Buenos Aires Province, is the largest and most populous Argentine province. It takes its name from the city of Buenos Aires, the capital of the country, which used to be part of the province and the province's capital until it was federalized in 1880. Since then, in spite of bearing the same name, the province does not include Buenos Aires proper, though it does include all other parts of the Greater Buenos Aires metropolitan area. The capital of the province is the city of La Plata, founded in 1882.
The Pampas are fertile South American lowlands that cover more than 1,200,000 square kilometres (460,000 sq mi) and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul. The vast plains are a natural region, interrupted only by the low Ventana and Tandil hills, near Bahía Blanca and Tandil (Argentina), with a height of 1,300 m (4,265 ft) and 500 m (1,640 ft), respectively.
Argentina has a vast territory and a variety of climates and microclimates ranging from tundra and polar in the south to the tropical climate in the north, through a vast expanse of temperate climate. Natural wonders include the Aconcagua, the highest mountain in the world outside the Himalayas, the widest river and estuary of the planet, the Iguazú Falls, the Humid Pampas, and the Argentine Sea. Visitors enjoy the culture, customs and Argentine cuisine.
Neuquén is the capital city of the Argentine province of Neuquén and of the Confluencia Department, located in the east of the province. It occupies a strip of land west of the confluence of the Limay and Neuquén rivers which form the Río Negro making it part of the ecoregion of Alto Valle del Río Negro. The city and surrounding area have a population of more than 340,000, making it the largest city in Patagonia. Along with the cities of Plottier and Cipolletti, it is part of the Neuquén – Plottier – Cipolletti conurbation.
The Sierra Morena is one of the main systems of mountain ranges in Spain. It stretches for 450 kilometres from east to west across the south of the Iberian Peninsula, forming the southern border of the Meseta Central plateau and providing the watershed between the valleys of the Guadiana to the north and the west, and the Guadalquivir to the south.
