Río Pilcomayo National Park : ウィキペディア英語版 | Río Pilcomayo National Park
}} The Río Pilcomayo National Park ((スペイン語:Parque Nacional Río Pilcomayo)) is a national park located in the northeastern part of the Argentine province of Formosa, on the border with Paraguay. Established on September 29, 1951 to protect the natural features (grasslands, marshes, creeks, lakes and forests), typical of the Humid Chaco ecoregion, the park is included in the Ramsar Convention's list of wetlands of international importance.〔 〕 ==Topography== The park occupies a large plain, which was formed when a depression in Paleozoic crystalline rocks was filled with organic and inorganic sediments, thus creating a sedimentary basin.〔 〕 The uppermost sediment levels are of fluvial and aeolian origin. The eastern parts of the park are dominated by silts and clays, creating less permeable soils, while the western parts contain soils that are coarser and more porous. There are fault lines that were generated during formation of the Andes, lying parallel to the Paraguay River. While the park's territory is gently sloping down from west to east, there is very little variety in elevation. The subtle differences become important in times of heavy rains and floods, when the area becomes inundated with pools of water connected by channels forming in the most low lying areas.
