This paper presents results on archaeological research conducted at the Cisnes river basin (~44° S), valley which passes through several environments in western Patagonia, from the westernmost limits of the steppe to the Pacific channels. These are assessed in light of a palaeoenvironmental reconstruction spanning from the Late Pleistocene to the Holocene. Results allow interpreting different ways for approaching the environment; these are exposed both spatially and chronologically. Cultural units defined occupied the space discontinuously and ranking it differentially attending to environmental variability. We correlate our data with available archaeological information for Aisén and adjacent areas. Additionally, we discuss cultural continuity and eventual interaction of steppe hunter-gatherers with peoples from the western archipelagic area.

The object of this work was to make a morphometric characterization of the Bobo river watershed in the Nariño department in Colombia. A map was created from topographical maps (1:25.000 scale) using the drainage network and the limit of each 2nd order microbasin as database. Dimensional, drainage network and relief morphometric parameters were evaluated for a later hy-drological study. The drainage area was 224.97 km2, having a 71.31 km perimeter. The Bobo river watershed is considered to be 6th order and has 176 2nd order drainage channels, 34 3rd order drainage channels, 9 4th order drainage channels and 3 5th order drainage channels. Average drainage density is 3.71km/km2, reflecting its high density, having strong, dissected geological formation. The area has a typical Andean land-use pattern, having native wooded vegetation, traditional transitory potato and vegetable growing predominating.
