Which mountains require oxygen?
Which mountains require oxygen? High altitude mountaineering. High-altitude climbing usually requires the use of portable oxygen apparatus when climbing Mount Everest or the other eight-thousanders, though some mountaineers have ascended Everest without oxygen.
Can I climb Everest without oxygen?

How long does it take to acclimate to altitude in Colorado?
Anecdotally, many locals will say it takes about one to three days to adjust to the air in cities like Denver, Salt Lake City, and Colorado Springs. However, everyone adjusts to higher altitudes differently—some people feel little to no difference, while others may take up to a week to feel normal.
Can you bring bodies down from Everest?
To retrieve a body takes a team of rescuers or Sherpa capable of digging out frozen bodies and bearing the extra weight of a frozen corpse down the mountain. The cost of such an expedition can climb above $70,000. Because of the cost and extreme risk to the retrieval team, few bodies ever leave Everest.
