>But as far as I understood from reading, the main difficulty was the technical climbing part. Combined with the low oxygen atmosphere and low temperature of high altitude. The danger of avalanches, weather changes, and the non-availability of rescue if anything goes wrong also plays a part. Alpine climbing is a package deal of difficulty and deadliness, and these aspects are hard to disentangle. Every competent alpine climbers does what they can to mitigate risks, but there is a very significant amount of risk that cannot be mitigated except by not doing difficult alpine climbing.
