Resumen

MENDEZ, César; REYES, Omar; NUEVO DELAUNAY, Amalia  y  GONZALEZ, Pablo. SYSTEMATIC SEARCH PROGRAM FOR EARLY EVIDENCE AND FINDING OF A FISHTAIL TYPE PROJECTILE POINT AT UPPER ÑIREHUAO RIVER. Magallania [online]. 2013, vol.41, n.2, pp.187-196. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442013000200010.

We present the finding of a "fishtail" type projectile point as result of a search program targeted to identify late Pleistocene glacial geoforms in the area of upper Ñirehuao (~45°20' S, Aisén, Chile). Framed within this program we carried out surface surveys by identifying the margins of a proglacial paleo-lake through air-photograph analysis. One of the most remarkable findings was obtained in the area of Pampa Coichel (BN 22), where the isolated lithic projectile point was recorded at an open-air location. This result is discussed in the frame of local, regional and supraregional information. Finally, we explore the potential of developing a program aimed to model old landscapes by isolating geomorphological variables in order to guide the search of early evidence.

Palabras clave : "fishtail" type projectile point; Central Patagonia; late Pleistocene.
