Cerro Tolosa

Cerro Tolosa is a mountain in Mendoza Province, Argentina.

Description

Cerro Tolosa is a summit in the Andes. The peak is located 110 kilometers west of the city of Mendoza, and 12.5 kilometers south of Aconcagua, in Aconcagua Provincial Park. Precipitation runoff from the mountain's slopes drains into tributaries the Mendoza River. Topographic relief is significant as the summit rises 2,250 meters above the Las Cuevas Valley in five kilometers. The first ascent of the summit was made in 1903 by Baroness Nadine Lougonine von Meyendorff and Alois Pollinger. The nearest higher peak is Cerro Mirador, 8.37 kilometers to the north-northeast.

Climate

According to the Köppen climate classification system, Cerro Tolosa is located in a tundra climate zone with cold, snowy winters, and cool summers. Weather systems are forced upward by the mountains, causing moisture to drop in the form of rain and snow. This climate supports the Glaciar del Hombre Cojo on the south slope. The months of November through March offer the most favorable weather for climbing in this area.
