Official Expedition Narrative & Archival Record
In early 1934, the first Polish Andean Expedition, organized by the Polish Tatra Society and led by Konstanty Narkiewicz-Jodko, entered the untracked valleys of the Argentine Andes. After achieving multiple first ascents in the Cordón de la Ramada massif (including Mercedario and Pico Polaco), the four climbers—Narkiewicz-Jodko, Stefan Daszyński, Stefan Osiecki, and Wiktor Ostrowski—approached the unclimbed eastern flank of Mount Aconcagua via the Relinchos valley. Confronting the vast, hanging ice sheet that now bears their nation's name, the climbers established Campamento Polacos at 5,800 metres. On March 8, 1934, fighting sub-zero temperatures, howling Andean gales, and razor-sharp penitente ice formations, they kicked steps and chopped bucket holds across sustained 50° to 65° blue ice. Breaching the summit ridge late in the afternoon, all four men stood on the 6,961-metre apex of the Americas. The Polish Glacier route became celebrated as the finest technical line on Aconcagua and the catalyst for Poland's golden tradition of high-altitude exploration.

Ascent Route & Topography

Polish Glacier (Aconcagua)
The Polish Glacier is the premier technical mountaineering route on Mount Aconcagua, ascending the steep eastern glaciated face over 1,000 vertical metres. Graded French D with sustained 50° to 65° slopes of hard alpine ice, it provides a dramatic, highly aesthetic alternative to the standard trekking route.
Target Objective Peak
Aconcagua
Aconcagua is the highest mountain in the Americas and the highest peak outside Asia, rising to 6,961 metres in Argentina's Andes. Celebrated as the second most topographically prominent mountain on Earth, it features colossal glaciated faces, intense high-altitude gales, and historic routes including the Polish Glacier.
