More than 8,000 permits were issued in the 2008 climbing season. Out of these, half were for people aiming for the summit. Aconcagua can be dangerous. The mountain is 6,962 metres high (22,840ft). Climbers tackle it without oxygen, and at its summit the air is 40% what it is at sea level.
The ''White Wind'' of Aconcagua - the clouds which descend quickly at the highest altitudes - can also catch climbers out. This year alone, 280 people had to be evacuated when they got into trouble. Many die, often from pulmonary embolisms or in accidents."
