Six climbers went missing last week at Mount Ranier in Washington. 

On Wednesday, six climbers reported their location as on Mount Rainier. Their message, sent via satellite phone at around 6 p.m., said where they were located and that they planned to set up camp in the park, according to the Seattle Times. However, when they did not report back by Friday, and a search and rescue team was sent.

The six climbers -- two guides and four clients -- had been climbing along Carbon Glacier some 9,500 feet up, rescuers determined by leftover debris in the area. According to Seattle Times, the route the group was taking toward Liberty Peak is prone to slides and is among the most advanced.

The company that employed the guides, Alpine Ascents, also employed the Sherpa guides who perished on Mount Everest. The search and rescue efforts, which included helicopters, were suspended four hours before dark on Saturday.

"This accident represents a horrific loss for our guide partners and the families and loved ones of every one of the climbers lost on the mountain," Randy King, superintendent of Mount Rainier National Park, said in a statement Saturday night. "The climbing community is a small one and a close one and a loss of this magnitude touches many. Our thoughts are with everyone affected by this tragic accident."

The Park Service has announced it will not put any rescue teams on the ground, but an airplane will make periodic flybys in the area. Once the snow melts, officials said, they will consider the possibility of a helicopter recovery.

One of the guides was identified as Matt Hegeman, the climb's leader, according to Alpine Ascents. Another of the victims has been identified as 26-year-old Mark Mahaney from St. Paul, according to the Minneapolis Star Tribune.

The young man had been an avid climber, according to relatives, and had climbed Mount Rainier once before.
