Skog was one of 14 to make it to the K2 summit that day. When she climbed back down, her husband was waiting to celebrate their impressive achievement.
"He was so happy. That was the way he was. He was ... he was so happy for us ... that we had that experience," Skog said. "He didn't need to be there himself."
Then suddenly tragedy struck as the group made their way back down to base camp.
While passing under a massive serac, or overhang of ice, a mini-avalanche struck the group. The falling ice cut safety ropes and swept Bae off the mountain.
In a daze, Skog managed to pick her way down to base camp in the dark. She hoped that her husband had survived the fall and would be waiting for her there.
"I just thought, 'OK, he has to be. Of course he's gone to the tent. He's in the tent,'" she said.
But Bae was gone.
And over the next several hours, many climbers would join him.
