Some of the specific challenges of descending Everest include:
* The descent route is often less well-marked than the ascent route, and climbers can easily become lost.
* The snow and ice on the descent route can be more treacherous, especially if it has been melted and refrozen.
* Climbers are often descending in darkness, which can make it more difficult to see the route and avoid hazards.
* The altitude can make it difficult to think clearly and make good decisions.
For all of these reasons, it is essential to have experienced guides who are familiar with the descent route and can help climbers stay safe.
