Tragic death in Peru
Every year we are contacted in connection with tragedies in the mountains. Understandably, many people choose not to speak out about the loss of their loved ones. We are grateful to those who do, because the best way to prevent more people from dying is to publicise the risks.

Please take the time to read some of the accounts of deaths at high altitude on this website, and this brave report from a son, describing how he lost his father in Peru in May 2012.

 We all live underneath a huge ocean of air that is several miles deep: the atmosphere. The pressure on our bodies is about the same as ten metres of sea water pressing down on us all the time.
