Altitude is generally divided into three stages: high altitude, 8,000 to 12, 000 feet; very high, 12,000 to 18,000; and extremely high, anything above 18,000 feet. Many areas in the Big Horn Mountains in Wyoming are in the high range. Pike’s Peak in Colorado is over 14,000 feet. Mount Shasta is also in this range, as are the Grand Tetons. In the Western hemisphere, Mount Aconcagua in South America is the extreme range at over 22,000 feet. Base camp on the Nepal side of Everest is just less than 18,000 feet. Everest summit is 29,000 feet.
