Rock glaciers and protalus ramparts are two of the main morphological features Central Andes in Province San Juan, Argentina. This sector has one highest densities occurrence rock world. In this region, which semiarid climatic characteristics, presence these landforms is important due to their solid state water reserves as resource regulators. Their vital several basins where, lack glaciers, debris-covered perennial snow patches, only solid-state reserves. However, topo-climatic factors controlling development evolution not well known, prevents an integrated management basins. contribution, first, analyzes spatial distribution active inactive with respect different topographic variables upper section Santa Cruz River basin. total, 375 have been inventoried, out 83 81 211 ramparts, covering area 13.09 km2 (3.03 % total area). The periglacial environment belt occurs between 4000 4200 m a.s.l. slopes a southwesterly aspect greater glaciers. Secondly, such addressed. While does seem be mainly controlled by analyzed, would elevation aspect. Besides, there local that contribute landforms.
