Lake Suesca is a natural water body situated on the Altiplano Cundiboyacense, belonging to the municipalities of Suesca and Cucunubá in the department of Cundinamarca, Colombia. The basin has a semi-elliptical shape that extends on a north–south axis, with roughly 6 kilometres (3.7 mi) length and 2 kilometres (1.2 mi) width. [1] The average depth is 8 metres (26 ft). It is located in the Eastern Ranges, on the anticlinal of Nemocón, in the northeast of the department, at an altitude of 2,800 metres (9,200 ft). [2]

Description

Geology and soils

Geologically, the lake is of Pleistocene origin and is linked to the formation of the Eastern Ranges, which had a strong uprising activity during the Pliocene. Because of its location there is a wide distribution of sedimentary rocks, and the Guadalupe Group, Guaduas, Bogotá and Cacho formations are present in the area. The basin is crossed along its axis by the Suesca Fault, uplifting sandstone. [2] [3] [4]

The soils of the basin are classified as alfisols, where erosion areas are classified as "bad soils". Generally these correspond to cold and dry climates, with corrugated relief and highly evolved soils, where the presence of erosion is common, and most horizons have enrichment with clay. These soils were formed during the Pliocene and Quaternary, containing deposits of volcanic ash from the Cordillera Central, which weathered into clays, currently present in the lower strata. [4]

Vegetation and climate

The original vegetation was composed of encenillo and "corono" forests, accompanied by more xerophytic Andean communities, which correspond to the Low montane dry forest (bs-MB) according to the Holdridge life zones. The actual land cover is dominated by exotic species, mostly Acacia decurrens , with few remnants of native vegetation in the north and south of the basin. [3] [4]

From a climatic point of view, the region has a bimodal rainfall regime, with an annual average of 647 mm, average temperatures of 14 °C, 70% relative humidity and evaporation of 1331 mm/year. The winds are a determinant factor for the vegetation and climate, as they are mainly influenced by Sabana de Bogotá, Magdalena River Valley and the Orinoco Plains, which converge in the area to generate specific characteristics from the point of view of moisture and the feasibility of rainfall. [3]

The region is under the jurisdiction of the Corporación Autonoma Regional de Cundinamarca (CAR) (environmental authority) and its central axis (north–south) serves as the boundary between the municipalities of Cucunubá and Suesca.

Muisca sacred lake

As with various other lakes on the Altiplano, Tota, Siecha, Guatavita and Iguaque, the Muisca who were the original inhabitants of the area before the Spanish conquest of the Muisca, performed religious rituals at Lake Suesca. [5]

Environmental issues

The basin has suffered severe deforestation and erosion, which together have negatively affected the lake ecosystem, which added to the impact of climate change have led to a significant reduction of the water surface. Plans for sustainable development are made in recent years. [6]

Since 1970, a soil remediation process with Acacia decurrens , Pinus patula and Eucalyptus globulus was started, but due to the lack of management, the problems related with water scarcity due to the reduction of runoff and water contained in the soil increased. Nowadays the entire basin is located within a forest reserve that has little management by the authorities.

By oral tradition, it is known that the lake had a great variety of species, such as "Guapucha" (Grundulus bogotensis ) and "Capitan de la Sabana" ( Eremophilus mutisii ), now locally extinct due to the desiccation of the water body and the introduction of carp and trout, which also disappeared by the same effect of El Niño in 1998. [7]

The lake is an important stop-over for many migratory birds, but few counting exercises have been made in the area.

Muisca architecture

This article describes the architecture of the Muisca. The Muisca, inhabiting the central highlands of the Colombian Andes, were one of the four great civilizations of the Americas. Unlike the three civilizations in present-day Mexico and Peru, they did not construct grand architecture of solid materials. While specialising in agriculture and gold-working, cloths and ceramics, their architecture was rather modest and made of non-permanent materials as wood and clay.

The Andean lake, at an average altitude of 2,540 metres (8,330 ft), was considered sacred in the religion of the Muisca who inhabited the area before the Spanish conquest of the Muisca in the 1530s.

Spanish conquest of the Muisca Part of the Spanish conquest of Colombia

The Spanish conquest of the Muisca took place from 1537 to 1540. The Muisca were the inhabitants of the central Andean highlands of Colombia before the arrival of the Spanish conquistadors. They were organised in a loose confederation of different rulers; the zipa of Bacatá, with his headquarters in Funza, the zaque of Boyacá, with his headquarters in Hunza, the iraca of the sacred City of the Sun Sugamuxi, the Tundama of Tundama, and several independent caciques. The leaders of the Confederation at the time of conquest were zipa Tisquesusa, zaque Quemuenchatocha, iraca Sugamuxi and Tundama in the northernmost portion of their territories. The Muisca were organised in small communities of circular enclosures, with a central square where the bohío of the cacique was located. They were called "Salt People" because of their extraction of salt in various locations throughout their territories, mainly in Zipaquirá, Nemocón, and Tausa. For the main part self-sufficient in their well-organised economy, the Muisca traded with the European conquistadors valuable products as gold, tumbaga, and emeralds with their neighbouring indigenous groups. In the Tenza Valley, to the east of the Altiplano Cundiboyacense where the majority of the Muisca lived, they extracted emeralds in Chivor and Somondoco. The economy of the Muisca was rooted in their agriculture with main products maize, yuca, potatoes, and various other cultivations elaborated on elevated fields. Agriculture had started around 3000 BCE on the Altiplano, following the preceramic Herrera Period and a long epoch of hunter-gatherers since the late Pleistocene. The earliest archaeological evidence of inhabitation in Colombia, and one of the oldest in South America, has been found in El Abra, dating to around 12,500 years BP.

Muisca art

This article describes the art produced by the Muisca. The Muisca established one of the four grand civilisations of the pre-Columbian Americas on the Altiplano Cundiboyacense in present-day central Colombia. Their various forms of art have been described in detail and include pottery, textiles, body art, hieroglyphs and rock art. While their architecture was modest compared to the Inca, Aztec and Maya civilisations, the Muisca are best known for their skilled goldworking. The Museo del Oro in the Colombian capital Bogotá houses the biggest collection of golden objects in the world, from various Colombian cultures including the Muisca.

Checua

Checua is a preceramic open area archaeological site in Nemocón, Cundinamarca, Colombia. The site is located 7 kilometres (4.3 mi) north of the town centre. At Checua, thousands of stone and bone tools, stone flakes and human remains have been found, indicating human occupation from around 8500 to 3000 years BP.

Eastern Hills (Bogotá)

The Eastern Hills are a chain of hills forming the eastern natural boundary of the Colombian capital Bogotá. They are part of the Altiplano Cundiboyacense, the high plateau of the Eastern Ranges of the Colombian Andes. The Eastern Hills are bordered by the Chingaza National Natural Park to the east, the Bogotá savanna to the west and north, and the Sumapaz Páramo to the south. The north-northeast to south-southwest trending mountain chain is 52 kilometres (32 mi) long and its width varies from 0.4 to 8 kilometres. The highest hilltops rise to 3,600 metres (11,800 ft) over the western flatlands at 2,600 metres (8,500 ft). The Torca River at the border with Chía in the north, the boquerón Chipaque to the south and the valley of the Teusacá River to the east are the hydrographic limits of the Eastern Hills.

Suárez River

The Suárez River, originally Saravita, is a river in the Eastern Ranges of the Colombian Andes. The river originates in Lake Fúquene on the border of Cundinamarca and Boyacá and its mouth is the confluence with the Chicamocha River, forming the Sogamoso River in Santander. It is part of the Magdalena Basin flowing towards the Caribbean Sea.

Sabana Formation Geological formation in the Colombian Andes

The Sabana Formation is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The formation consists mainly of shales with at the edges of the Bogotá savanna lignites and sandstones. The Sabana Formation dates to the Quaternary period; Middle to Late Pleistocene epoch, and has a maximum thickness of 320 metres (1,050 ft), varying greatly across the savanna. It is the uppermost formation of the lacustrine and fluvio-glacial sediments of paleolake Humboldt, that existed at the edge of the Eastern Hills until the latest Pleistocene.
