As the highest peak outside of Asia, Aconcagua is also the tallest mountain in the Western Hemisphere and the Southern Hemisphere. It is situated close to the Chilean border in Mendoza Province, and its precise elevation has been a source of contention for more than a century. It was first summitted in 1897 by Swiss climber Matthias Zurbriggen.
