Resumen:
The role of the Santa Cruz River in human circulation in Patagonia has long been discussed. In this paper we present new information generated in rescue works related to the construction of dams, which we analized in conjunction with the one obtained in research projects in order to obtain information regarding this topic.During the Late Holocene, technological, raw material, burial and genetic information suggests the existence of different human cultural groups both North and South of the Santa Cruz River An abandonment of the area took place by ca. 1000 yr B.P., during the so-called Medieval Climatic Anomaly. After ca. 500 B.P., the presence of new human groups was recorded in the Upper Santa Cruz River, as suggested by technological, raw material, burial and genetic evidenceAlthough until the moment, rock art could not be dated within this basin, there are clear differences North and South of the River. North of the River, engravings are very frequent, contrary to its existence to the South of it. We agree with Charlin & Borrero about the relevance of this difference, specially taking into account the better preservation potential of engravings in relationship to paintings. Very recently, their presence was identified in localized places at the Pali Aike volcanic field and between the Gallegos and Chico Rivers.During rescue works the presence of engravings and painting was identified at La Porfiada, a volcanic outcroup located South of the River, in its middle Basin. Information obtained at rockshelters La Porfiada 1 and 2 indicates the presence hand negatives and engravings, including in the last case human feets and guanaco. Both motifs are present to the North of the River, although differences in the engravings techniques in the case of guanaco can be seen. Until the moment, engravings were not identified in the Upper Santa Cruz Basin, which shows similarities with the motifs and techniques present to the South. IN addition, hand negatives were only identified at Punta Bonita-Walichu archaeological locality, at the Upper Santa Cruz river basin. Although surface material at the right margin of the Middle Santa Cruz river basin, shows technological similarities with archaeological materials identified at the Upper Santa Cruz River, rock motifs and techniques are different. These differences can probably be attributed to changes in human circulation through time, a hypothesis which remains to be tested. Surprisingly, rock motifs and techniques show more similarities with the ones frequent in the canyons to the North, providing additional evidence of human circulation across the Santa Cruz River. It is possible to think that the crossing of the River took place in the vicinity of the area, a hypothesis which remains to be proved.
