Cueva de las Manos (Spanish for Cave of the Hands or Cave of Hands) is a cave and complex of rock art sites in the province of Santa Cruz, Argentina, south of the town of Perito Moreno. It is named for the hundreds of paintings of hands stenciled, in multiple collages, on the rock walls. The art was created in several waves between 7,300 BC and 700 AD, during the Archaic period of pre-Columbian South America. The age of the paintings was calculated from the remains of bone pipes used for spraying the paint on the wall of the cave to create the artwork, radiocarbon dating of the artwork, and stratigraphic dating.
The site is considered by some scholars to be the best material evidence of early South American hunter-gatherer groups. Argentine surveyor and archaeologist Carlos J. Gradin and his team conducted the most important research on the site in 1964, when they began excavating sites during a 30-year study of cave art in and around Cueva de las Manos. The site is a National Historic Monument in Argentina and a UNESCO World Heritage Site.
Cueva de las Manos refers to both the main site of the cave and the surrounding complex of rock art sites that includes it. The cave lies at the base of a stepped cliff in the Pinturas River Canyon, in the upper part of the Deseado River basin, in an isolated part of Patagonia. It is about south of Perito Moreno, a town in northwest Santa Cruz Province, Argentina. It is part of both Perito Moreno National Park and Cueva de las Manos Provincial Park.
During the time of the Paleoindians, around the late Pleistocene to early Holocene geological periods, the areas between above sea level formed a microclimate in the canyon promoting a grassland ecosystem hospitable to many animals. This ecosystem included the Schinus molle plant, which was used to form resins and adhesives and as a source of firewood. It was also home to edible vegetables and plants that could be used for medicine; tubers, such as the rush root; and numerous fruits, such as that of the Berberis plant.

Argentina (aɾxenˈtina), officially the Argentine Republic (República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south.
The Tehuelche people, also called the Aónikenk, are an indigenous people from eastern Patagonia in South America. In the 18th and 19th centuries the Tehuelche were influenced by Mapuche people, and many adopted a horseriding lifestyle. Once a nomadic people, the lands of the Tehuelche were colonized in the 19th century by Argentina and Chile, gradually disrupting their traditional economies. The establishment of large sheep farming estates in Patagonia was particularly detrimental to the Tehuelche.
In archaeology, rock art is human-made markings placed on natural surfaces, typically vertical stone surfaces. A high proportion of surviving historic and prehistoric rock art is found in caves or partly enclosed rock shelters; this type also may be called cave art or parietal art. A global phenomenon, rock art is found in many culturally diverse regions of the world. It has been produced in many contexts throughout human history.
A new grid-based method is proposed for predicting the behaviour of colour printers. The method takes into account the varying density of dots as well as the light diffusion in the paper by defining at different intensity levels different colorimetric valu ...
