Madrid (Spanish pronunciation: [maˈðɾið]) is a city and municipality in the Western Savanna Province, part of the department of Cundinamarca, Colombia. The city is located 21 kilometres (13 mi) from the capital Bogotá. The city's main and biggest industry is the growing of flowers, especially roses which are mostly exported to the United States and Japan. Madrid borders Bojacá, El Rosal, Facatativá, Funza, Mosquera, Sibaté, Soacha, Subachoque, Tabio and Tenjo.

Mosquera is a municipality of Colombia in the Western Savanna Province, part of the department of Cundinamarca. Mosquera is close to the capital Bogotá and is part of its metropolitan area. The urban centre of Mosquera is situated at an altitude of 2,516 metres (8,255 ft) on the Bogotá savanna. The municipality borders the localities Bosa and Fontibón of Bogotá in the east, Soacha in the south, Madrid and Funza in the north and Bojacá in the west.

The Sabana Formation (Spanish: Formación Sabana, Q1sa, QTs) 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. The uppermost sediments of the Sabana Formation were deposited during the Last Glacial Maximum, a time when the first humans populated the Bogotá savanna. These hunter-gatherers used the bones of the still extant Pleistocene megafauna as Notiomastodon platensis, Cuvieronius hyodon and Equus neogeus, of which fossils have been found in the Sabana Formation. Knowledge about the formation has been provided by geologists Alberto Guerrero, Thomas van der Hammen and others.

Funza (Spanish pronunciation: [ˈfunsa]) is a municipality and town of Colombia in the Western Savanna Province, of the department of Cundinamarca. Funza is situated on the Bogotá savanna, the southwestern part of the Altiplano Cundiboyacense with the urban centre at an altitude of 2,548 metres (8,360 ft). In Funza the La Florida wetland, part of the wetlands of Bogotá, a remnant of the Pleistocene Lake Humboldt, still exists. The town is part of the Metropolitan Area of Bogotá and borders Madrid and Tenjo in the north, Mosquera in the south, Madrid in the west and Cota and the locality Engativá of the capital Bogotá in the east. The eastern boundary is formed by the Bogotá River. Funza is the site of the former main settlement Bacatá of the Muisca Confederation. Modern Funza was founded by Gonzalo Jiménez de Quesada during the Spanish conquest of the Muisca on April 20, 1537.

Bacatá (Chibcha: Muyquytá or Muequetá) is the name given to the main settlement of the Muisca Confederation on the Bogotá savanna. It mostly refers to an area, rather than an individual village, although the name is also found in texts referring to the modern settlement of Funza, in the centre of the savanna. Bacatá was the main seat of the zipa, the ruler of the Bogotá savanna and adjacent areas. The name of the Colombian capital, Bogotá, is derived from Bacatá, but founded as Santafe de Bogotá in the western foothills of the Eastern Hills in a different location than the original settlement Bacatá, west of the Bogotá River, eventually named after Bacatá as well. The word is a combination of the Chibcha words bac, ca and tá, and means "(enclosure) outside the farmfields", referring to the rich agricultural lands of the Sabana Formation on the Bogotá savanna. Bacatá was submitted to the Spanish Empire by the conquistadors led by Gonzalo Jiménez de Quesada on April 20, 1537. Santafe de Bogotá, the capital of the New Kingdom of Granada, was formally founded on August 6, 1538. The last zipa of an independent Bacatá was Tisquesusa, who died after being stabbed by a Spanish soldier. His brother, Sagipa, succeeded him and served as last zipa under Spanish rule. The name Bacatá is maintained in the highest skyscraper of Colombia, BD Bacatá, and in the important fossil find in the Bogotá Formation; Etayoa bacatensis.

Bojacá is a municipality and town of the Western Savanna Province, Colombia in the department of Cundinamarca. The urban centre is situated at an altitude of 2,598 metres (8,524 ft) on the Bogotá savanna at 40 kilometres (25 mi) from the capital Bogotá. The municipality borders Zipacón, Madrid and Facatativá in the north, Madrid and Mosquera in the east, Soacha and San Antonio del Tequendama in the south and Tena, La Mesa and Zipacón in the west.

The Tunjuelo or Tunjuelito River is a river on the Bogotá savanna and a left tributary of the Bogotá River. The river, with a length of 73 kilometres (45 mi) originates in the Sumapaz Páramo and flows northward through the Usme Synclinal to enter the Colombian capital Bogotá. There, the river is mostly canalised flowing westward into the Bogotá River. It is one of the three main rivers of the city, together with the Fucha and Juan Amarillo Rivers.

Aguazuque is a pre-Columbian archaeological site located in the western part of the municipality Soacha, close to the municipalities Mosquera and San Antonio del Tequendama in Cundinamarca, Colombia. It exists of evidences of human settlement of hunter-gatherers and in the ultimate phase primitive farmers. The site is situated on the Bogotá savanna, the relatively flat highland of the Altiplano Cundiboyacense close to the present-day course of the Bogotá River at an altitude of 2,600 metres (8,500 ft) above sea level. Aguazuque is just north of another Andean preceramic archaeological site; the rock shelter Tequendama and a few kilometres south of Lake Herrera. The artefacts found mostly belong to the preceramic period, and have been dated to 5025 to 2725 BP (3000 to 700 BCE). Thus, the younger finds also pertain to the later ceramic Herrera Period. There were some difficulties in dating of the uppermost layer due to modern agricultural activity in the area; the sediments of the shallower parts were disturbed. At Aguazuque multiple palaeoanthropological finds have been made; stone and bone tools, remains of fireplaces and a multitude of pre-Columbian foods, primitive circular housing, various burial sites of individual and group interments and in the youngest dated layers, evidences of ceramics. The site represents a transition from a hunter-gatherer culture towards the earliest evidence of agriculture. A phase of settlement is attested where the people moved away from the caves and rock shelters and started inhabiting open area grounds. Investigation of Aguazuque has been conducted since 1986, mainly by archaeologist Gonzalo Correal Urrego who published the results of his studies in the book Aguazuque - evidencias de cazadores, recolectores y plantadores en la altiplanicie de la Cordillera Oriental in 1990.

La Isla is a small wetland, part of the wetlands of Bogotá. It is located next to the Tunjuelo River in the locality Bosa, Bogotá, Colombia. The Bogotá River passes 800 metres (2,600 ft) south of the wetland with an area of 7.7 hectares (19 acres).

The Cacho Formation (Spanish: Formación Cacho, E1C, Tpc, Tec) is a geological formation of the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes. The predominantly sandstone formation with thin intercalated beds of shales dates to the Paleogene period; Middle to Late Paleocene epochs, and has a maximum thickness of 400 metres (1,300 ft).

Meandro del Say is a wetland, part of the wetlands of Bogotá. It spans the locality Fontibón of Bogotá and the eastern part of Mosquera, Cundinamarca.

Meandro de Say is situated in the Fucha River basin.
