n the past, conflicting data could be found regarding the heights of Ojos del Salado and Cerro Pisses. However, an international team measured the mountains with DGPS and confirmed that "Pisses" is the third highest mountain of South America.
In 2003 a young British mountaineer, Neil Tucker, disappeared on this mountain. Despite his young age (he was only 24 years) he was the pioneer of the "21 world summits " project. According to my research he was the first who wanted to climb the 3 highest peaks on each continent. He disappeared during his descent under unknown circumstances. His corps was never found.
