What is summit fever?

Answer 1

"Summit fever had developed in that group," he said. "There was a chemistry in there that meant they were going for the summit no matter what ... They were all driving each other on. These people came together and because of the place and the atmosphere and their personalities, they became blinkered and simply focused on the top. There was no careful awareness in the group and the most dangerous thing about groups is that everyone hands over responsibility for themselves to someone else ... It means that no one is taking responsibility. There can be a false sense of strength in numbers, but it doesn't matter how big your group is - you can have 1,000 people and the mountain could still kill them all."
