Hundreds of hands stencilled onto rock in a Patagonian canyon, overlapping in collages, more than 2,000 of them, made between about 7300 BC and AD 700 across several distinct periods. They were made by holding a hand to the wall and blowing pigment through a bone pipe, and there is a detail in the count that puts you right next to the person: 829 of the hands are left hands and only 31 are right, because almost everyone held the pipe in their right hand and sprayed their left. UNESCO listed it in 1999 and Argentina made it a national historic monument in 1993. Three gravel roads get you close, the shortest 22 km plus a 4 km walk, and you must go with an authorised guide. Santa Cruz Province, about 163 km south of Perito Moreno town.
