Aguja Mermoz is a mountain in Santa Cruz Province, Argentina.
Aguja Mermoz is a summit in the Andes. The peak is located one kilometer (0.6 mile) northeast of Fitz Roy and 13 kilometers (8 miles) northwest of El Chaltén, in Los Glaciares National Park of Patagonia. Precipitation runoff from the mountain's slopes drains to Viedma Lake. Topographic relief is significant as the summit rises 1,510 meters (4,954 ft) above Laguna Piedras Blancas in 4.5 kilometers (2.8 miles), and 1,250 meters (4,100 ft) above the North Fitz Roy Glacier in one kilometer (0.6 mi). The first ascent of the summit was made in 1974 by Héctor Cuiñas, FermÃÂn Olaechea, and Guillermo Vieiro via the northwest face. The toponym, which translates as Mermoz Needle, was applied by Louis Lliboutry in 1952 to honor Jean Mermoz (1901âÂÂ1936), a pioneer aviator in South America. The nearest higher peak is Fitz Roy, 0.96 kilometer (0.6 mile) to the south-southwest.

According to the Köppen climate classification system, Aguja Mermoz is located in a tundra climate zone with cold, snowy winters, and cool summers. Weather systems are forced upward by the mountains (orographic lift), causing moisture to drop in the form of rain and snow. This climate supports the Piedras Blancas Glacier below the east slope of the peak and the North Fitz Roy Glacier to the west. The months of November through March offer the most favorable weather for visiting or climbing in this area.
