Aconcagua by this hike represents the same expedition made in 1934 by the Poles Ostrowski, Karpinski, Osiecki and Narkievicz, hiking by East-North-East. They are considered the first ones to discover how to climb Aconcagua by one side of the Polish Glacier, also called False Polish, where we find better views than the Normal route. This expedition ascent and descend through the Vacas Valley and Plaza Argentina base camp.
