How does krakauer describe camp?

Jon Krakauer describes Camp IV as a "city of tents" that is perched on a narrow ridge at 26,000 feet. He notes that the camp is a hub of activity, with climbers coming and going at all hours of the day and night. He also mentions that the camp is located in a very dangerous area, and that climbers must be constantly aware of the risk of avalanches, icefalls, and altitude sickness.
