Geri Winkler
In the 1990s he ascended Popocatepetl in Mexico and Muztagh Ata (7546 m) in China. In the summer of 2001, he climbed Elbrus in Russia, the highest mountain in Europe. In the winter of 2002 and 2003, Winkler climbed Aconcagua in Argentina, the tallest mountain in South America.
Nevado de Chañi
The Nevado de Chañi is a compact mountain group located between the meridians of longitude West 65º42’ and 65º48’ and the parallels of latitude South 24º00’ and 24º10’. The main summit (according to the last available surveys) is 5,949m (24º03’S and 65º44’W) and it is the highest point in the province of Jujuy. There is some confusion about the height of the mountain. Official, but old, official surveys from the Argentine IGM (the military geographic institute) give a height of 6,200 which is an exaggeration. Some more recent surveys give about 5,900. The height of 5,949 has been measured many times with modern global positioning systems by summiteers since the early 2000s.
