Cueva de las Manos
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, 163 km (101 mi) 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 AD 700, 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 165 km (103 mi) 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 400 and 500 meters (1,300 and 1,600 ft) 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.
The current climate of the cave area can be described as precordilleran steppe (or "grassy foothills"). The climate is cold and dry, with very low humidity. Ian N. M. Wainwright and colleagues state that the area receives a total annual precipitation of less than 20 mm (0.79 in) per year, while Gladys I. Galende and Rocío Vega state that it averages 200 mm (7.9 in) per year. The topography of the canyon blocks the strong westward winds that are common in the region, making winters less severe. The average temperature is 8 °C (46 °F), with extreme highs of around 38 °C (100 °F) and extreme lows of around −10 °C (14 °F). The coldest month is July, and the warmest month is February, which average −3 °C (27 °F) and 21 °C (70 °F), respectively.
In ancient times, people accessed the Pinturas Canyon, and by extension the cave area, through ravines in the east and west, typically from higher elevations around 600 to 700 meters (2,000 to 2,300 ft) above sea level. Currently, there are three gravel roads that lead to the site: a 46 km (29 mi) route from the south, starting near Bajo Caracoles, and two more further north, a 28 km (17 mi) route from Ruta 40 (Route 40) and a 22 km (14 mi) route that ends with a 4 km (2.5 mi) foot trail.
When the site was occupied, the Pinturas and Deseado Rivers drained into the Atlantic Ocean and provided water for herds of guanacos, making the area attractive to Paleoindians. As the glacial ice fields melted, the Baker River captured the drainage of the eastward flowing rivers. The resulting reduction in water levels of the Pinturas and Deseado rivers led to a progressive abandonment of the Cueva de las Manos site.
Projectile points, a bola stone fragment, side-scrapers, and fire pits have been found alongside the remains of guanaco, puma, fox, birds, and other small animals. Guanacos were the natives' primary food source; hunting methods included bolas, ambushes, and game drives, in which they would drive guanacos into ravines and other confined areas to better collectively hunt them. This technique is recorded in the art of the cave, and shows how the topography of the area influenced the art and how it was created. Dart and spear throwers are also depicted, although there is little archaeological evidence of these types of weapons being used in Patagonia.
