## Summits Overview (96 Peaks)
* **Aconcagua**: Elevation 6961m | Prominence 6961m | Countries: AR | First Ascent: 1897-01-14 by Matthias Zurbriggen | Subrange: Situated entirely within Mendoza Province near the Chilean border, Aconcagua rises above the Horcones and Vacas river valleys. While its northern flank offers non-technical scree ascents, its eastern aspect is draped by the sweeping Polish Glacier, and its dramatic South Face plunges 2,700 vertical metres in sheer rock and hanging ice.
