“14,000 Feet: Many people will be showing serious signs and symptoms of Acute Mountain Sickness (AMS). Some people may be experiencing visions and hallucinations. Many people will be displaying mental impairment, often called “Summit Brainâ€�. Immediate descent to lower altitude is recommended for these people. Most people will be in oxygen starvation, also known as Asphyxia.”
