Morenas Coloradas Rockglacier
Contributing Station Information

The study area is situated in the Andean Cordillera of Mendoza, a region frequently referred to as Central Andes. It comprises the area between 31° and 35° S approximately. This region belongs to the southernmost part of the Dry Andes. The valley of Morenas Coloradas, in the Cordón del Plata, Cordillera Frontal, in the Argentine province of Mendoza was chosen as an outstanding and at the same time representative cryogenic example of the region.

The valley of Morenas Coloradas (SE) consists of a composed rockglacier, of the tongue-shaped type, with interrelated and superimposed frozen bodies consisting of cryogenic sediments derived from morainic till.

A tiny glacier remains at the tip of the valley but it continues with a covered glacier with a length of 2.5 km at a height of over 4200m. Moreover, the valley is occupied by a covered glacier, moraines with ice cores or islands of ice covered by till and one very small section of uncovered ice at the tip of the valley.
