What started Monday as a one-day hike on a mountain turned into an unfortunate experience that led to the death of one person.

According to the Seattle Times, one climber died Tuesday morning on Mount Rainer while he and two other climbers were heading down the mountain. Authorities said that a storm caught the three climbers, but they managed to get to Anvil Rock on the Muir Snowfield, a half-mile from Camp Muir.

Kevin Bacher, a spokesman for Mount Rainier National Park, said that they spend Monday night on the mountain and, because the weather was really bad, the helicopters that were sent to take them couldn’t break through the storm. Unfortunately the climbers were forced to spend another night out there.

Because the conditions were really bad, one of them didn’t make it through and died before the rescue crews could arrive. The other two were suffering from hypothermia and frostbite.

Even when the weather cleared out a bit, the helicopter was still unable to get to them. Bacher said that, around 7:15 a.m., one of the climbers managed to arrive at Camp Muir, telling rangers the location of the other two. In 15 minutes, rescuers made it to Anvil Rock and took the victims.

Apparently, the three hikers, a doctor, his wife and another man, were experienced climbers but the storm forced them to stay at Anvil Rock. They tried to call 911 but the connection was very bad and the park ranger didn’t know what was happening.

According to the Seattle Times, Bacher said that they reached help Tuesday, around 3:30 a.m.

By 8:30 the climbers had been transported to Camp Muir and doctors began taking care of the two survivors, a man and a woman.

Bacher said that even experienced mountaineers could be overwhelmed by storms, adding that the weather could change very quickly on the mountain. Authorities didn’t reveal the victims’ identities.
