According to a report from The Associated Press, there are no plans on Sunday to recover the bodies of six missing climbers at Mt. Rainier National Park. Patti Wold, a spokesperson for the park, stated that rescue attempts would not be made on Sunday due to the heightened danger of ice and rock falls for rescuers.

A crew searching the area by helicopter on Saturday did locate camping equipment in an area prone to avalanches. It is believed the climbers may have succumbed to a 3,300 foot fall in this area.

Wold commented, “there’s no certainty that recovery is possible given the location.”

This incident is considered one of the worst alpine disasters in decades, according to The Seattle Times. Four of the climbers made plans to climb the Liberty Ridge route which is considered one of the most difficult and advanced options on the mountain. They were accompanied by two professional guides from the climbing company, Alpine Ascents International. After the group failed to return at their scheduled time on Friday, park officials were notified and a search process was initiated.

In the coming weeks and months, the area will be searched periodically by air based on weather conditions. Officials have yet to release the names of those involved in the accident.

According to the Los Angeles Times, 89 people have died since 1987 while attempting to climb Mt. Rainier.
