| Sumario: | Eolian climbing dunes found in the sierra de Los Tarjados (south of the La Rioja province> Argentina) are described in this paper. According to their morphology two mayor types of dunes have been recognized: 1) climbing dunes associated to ramp deposits, which can ascent the mountain front; and 2) climbing dunes do not related to ramps and where deflationary channel developed between the dune front and the cliff. Climbing dunes sands show finer mean grain-size, better sorting and lower skewness than associated sand sheet deposits |
