Getting Used to the Mountain

There are many climbers who dream of climbing Everest.  But the temprature is so cold, and the oxygen level is veryl low, its hard for you to get used to the mountain.  Here's how they do it.  On the first day, the climbers set up a camp at the base of the mountain.  For the next few days they climb up and down the mountain in order to let their bodies get used to the cold tempratures and the oxygen levels. When the climbers gradually move up the mountain, they set up camp at different levels.  These levels are: 

• Base Camp - 17,500ft
• Camp 1 - 20,000ft
• Camp 2 - 21,300ft
• Camp 3 - 24,000ft
• Camp 4 - 26,000ft
• Summit - 29,035ft
