A lost city is an urban settlement that fell into terminal decline and became extensively or completely uninhabited, with the consequence that the site's former significance was no longer known to the wider world. The locations of many lost cities have been forgotten, but some have been rediscovered and studied extensively by scientists. Recently abandoned cities or cities whose location was never in question might be referred to as ruins or ghost towns. Smaller settlements may be referred to as abandoned villages. The search for such lost cities by European explorers and adventurers in Africa, the Americas, and Southeast Asia from the 15th century onwards eventually led to the development of archaeology.
Lidar is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction or it may scan multiple directions, in which case it is known as lidar scanning or 3D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications.
The Amazon rainforest, also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 5,500,000 km2 (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations and 3,344 formally acknowledged indigenous territories.
Mohenjo-daro is an archaeological site in Larkana District, Sindh, Pakistan. Built c. 2500 BCE, it was the largest settlement of the ancient Indus Valley Civilisation, and one of the world's earliest major cities, contemporaneous with the civilizations of ancient Egypt, Mesopotamia, Minoan Crete, and Norte Chico.
In the history of the Americas, the pre-Columbian era, also known as the pre-contact era, spans from the original peopling of the Americas in the Upper Paleolithic to European colonization, which began with Christopher Columbus's voyage of 1492. Usually, the era covers the history of Indigenous cultures until significant influence by Europeans. This may have occurred decades or even centuries after Columbus for certain cultures.
Lothal was one of the southernmost sites of the ancient Indus Valley civilisation, located in the Bhal region of the Indian state of Gujarat. Construction of the city is believed to have begun around 2200 BCE.
Amazonas is a state of Brazil, located in the North Region in the north-western corner of the country. It is the largest Brazilian state by area and the ninth-largest country subdivision in the world. It is the largest country subdivision in South America, being greater than the areas of Chile, Paraguay, and Uruguay combined. Mostly located in the Southern Hemisphere, Amazonas is the third-largest country subdivision in the Southern Hemisphere after the Australian states of Western Australia and Queensland. Located entirely in the Western Hemisphere, it is the fourth-largest country subdivision in the Western Hemisphere after Greenland, Nunavut, and Alaska. If independent, Amazonas could become the sixteenth-largest country in the world, slightly larger than Mongolia. Neighbouring states are Roraima, Pará, Mato Grosso, Rondônia, and Acre. It also borders the nations of Peru, Colombia and Venezuela. This includes the Departments of Amazonas, Vaupés and Guainía in Colombia, as well as the Amazonas state in Venezuela, and the Loreto Region in Peru.
A cradle of civilization is a location and a culture where civilization was developed independent of other civilizations in other locations. The formation of urban settlements (cities) is the primary characteristic of a society that can be characterized as "civilized". Other characteristics of civilization include a sedentary non-nomadic population, monumental architecture, the existence of social classes and inequality, and the creation of a writing system for communication. The transition from simpler societies to the complex society of a civilization is gradual.
Amazonas is a department and region in northern Peru bordered by Ecuador on the north and west, Cajamarca on the west, La Libertad on the south, and Loreto and San Martín on the east. Its capital is the city of Chachapoyas.
The Chachapoyas, also called the "Warriors of the Clouds", was a culture of the Andes living in the cloud forests of the southern part of the Department of Amazonas of present-day Peru. The Inca Empire conquered their civilization shortly before the Spanish conquest in the 16th century. At the time of the arrival of the conquistadors, the Chachapoyas were one of the many nations ruled by the Incas, although their incorporation had been difficult due to their constant resistance to Inca troops.
Jaén, founded as San Leandro de Jaén and then known as Jerez de la Frontera and finally as Jaén de Bracamoros since April 1549, is a city which is the capital of the Jaén Province in the Cajamarca Region in Peru, located in the high jungle of northern Peru. It is the seat of the Catholic Apostolic Vicariate of St. Francis Xavier, also known as Apostolic Vicariate of Jaén en Peru.
Sangay is an active stratovolcano in central Ecuador. It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today.
Guayabo National Monument, is an archaeological site near the city of Turrialba, within the Central Conservation Area in the Cartago Province, Costa Rica. It is almost directly in the center of the country on the Southern slope of the Turrialba Volcano. The National Monument covers about 2.3 square kilometres (0.89 sq mi) and is surrounded by rainforest plant vegetation causing it to be extremely vibrant green due to high precipitation and rich soils. Only a small portion of it has been unearthed, excavated, and studied.
Ixkun is a pre-Columbian Maya archaeological site, situated in the Petén Basin region of the southern Maya lowlands. It lies to the north of the town of Dolores, in the modern-day department of Petén, Guatemala. It is a large site containing many unrestored mounds and ruins and is the best known archaeological site within the municipality of Dolores.
Yaxha is a Mesoamerican archaeological site in the northeast of the Petén Basin in modern-day Guatemala. As a ceremonial centre of the pre-Columbian Maya civilization, Yaxha was the third largest city in the region and experienced its maximum power during the Early Classic period.
In archaeology, earthworks are artificial changes in land level, typically made from piles of artificially placed or sculpted rocks and soil. Earthworks can themselves be archaeological features, or they can show features beneath the surface.
The Lost City of Z: A Tale of Deadly Obsession in the Amazon is a non-fiction book by American author David Grann. Published in 2009, the book recounts the activities of the British explorer Percy Fawcett who, in 1925, disappeared with his son in the Amazon rainforest while looking for the ancient "Lost City of Z". In the book, Grann recounts his own journey into the Amazon, by which he discovered new evidence about how Fawcett may have died.
The Upano River is a river of Ecuador. This river runs from the sierra to the depths of the Amazon. The river is mainly used locally for fishing, there is also rafting and kayaking offered out of Macas. The Rio Upano is known for its fossils, sandy beaches and many hot springs. There are numerous river overlooks including one a block from the central park of Logroño. There is also a cable car that crosses the river outside of Logroño across from Shuar Community.
The Llanos de Moxos, also known as the Llanos de Mojos and the Beni Savanna, have extensive remains of pre-Columbian agricultural societies scattered over most of Beni Department, Bolivia. The remains testify to a well-organized and numerous indigenous people. This contradicts the traditional view of archaeologists, notably Betty Meggers, who asserted that the Amazon River Basin was not environmentally able to sustain a large population and that its indigenous inhabitants were hunter-gatherer bands or slash-and-burn farmers. In the 1960s, petroleum company geologists and geographer William Denevan were among the first to publicize the existence of extensive prehistoric earthworks constructed in the Amazon, especially in the Llanos de Moxos.
