A water channel to drain and irrigate andenes. Andenes were complicated to build, requiring provisions for drainage and irrigation. The first step in constructing an andén was to lay an underground or bedrock foundation about 1 metre (3.3 ft) deep to lend strength and stability to the retaining wall, which might rise about 2 metres (6.6 ft) above the slope of the ground.
Terraces were built to permit agriculture in the rugged terrain of the Andes. The heartland of the Inca Empire was in the high plateaus and mountains of the Andes of Peru. This area is mostly above 3,000 metres (9,800 ft) in elevation and is characterized by low or seasonal precipitation, low temperatures, and thin soils.
Nested fill terraces: Nested fill terraces are the result of the valley filling with alluvium, the alluvium being incised, and the valley filling again with material but to a lower level than before. The terrace that results for the second filling is a nested terrace because it has been “nested” into the original alluvium and created a terrace.
A terrace in agriculture is a flat surface that has been cut into hills or mountains to provide areas for the cultivation for crops, as a method of more effective farming. Terrace agriculture or cultivation is when these platforms are created successively down the terrain in a pattern that resembles the steps of a staircase.
Located thirteen miles east of Cuzco in the Cuzco Valley, this ensemble of ruins was once an estate for the Inca elite and nobility. The aqueducts of this area are set atop walls that predate the Inca occupation of the area. Scholars believe these walls too have been built by the Wari civilization. After the Inca took control of Tipón in ...
"Indian Reserve" is a historical term for the largely uncolonized land in North America that was claimed by France, ceded to Great Britain through the Treaty of Paris (1763) at the end of the Seven Years' War—also known as the French and Indian War—and set aside for the First Nations in the Royal Proclamation of 1763.
The Southern Andes in Argentina and Chile, south of Llullaillaco, The Central Andes in Peru and Bolivia, and The Northern Andes in Venezuela, Colombia, and Ecuador. At the northern end of the Andes, the separate Sierra Nevada de Santa Marta range is often, but not always, treated as part of the Northern Andes. [3]
The rugged topography of the Central Andes creates the warm, dry valleys that typifies the valles. Generally lying between 1,200 and 3,500 meters above sea level (m.a.s.l.) or 4,000 - 13,000 feet above sea level. Much of the area features steep hillsides and deep canyons, including the world's deepest canyon, the Colca Canyon.
