"They were hugging themselves like a baby in a mother's belly, folded into themselves," Ben Yehuda said.
Ben Yehuda encountered another body in an ice crack 984 feet below the summit. The man had only one crampon on -- no gloves, no mask. His ice-white face was swollen with frostbite. He was wearing a familiar hat.
It was Aydin Irmak, a 46-year-old Turk Nadav knew from base camp. They had played cards. Nadav had warned Irmak in Camp 4 not to join the crowd cluttering Everest's face.
Again, Ben Yehuda touched the body. The man groaned. He was disoriented and unconscious, but alive -- a miracle considering his exposure in the death zone.
Ben Yehuda decided to forego his summit attempt. This man was not going to die. Ben Yehuda was going to get them down, and he knew it meant they both might die.
Ben Yehuda connected Irmak, a man roughly his own weight, to his rappelling harness and began to maneuver them down. Soon, Ben Yehuda's oxygen mask froze.
"It's like someone is taking a belt and putting it around your neck and pulling as hard as they can," Nadav said. "I thought we would become part of the mountain for sure."
An hour into the descent, Ben Yehuda removed the mitten covering two gloves on his right hand so he could hold Irmak and the rope more securely. Minutes later, his right hand froze in position, clenching the rope.
He cursed, over and over, suspecting he would lose his fingers.
They passed a Malaysian man, attached to the ropes by his harness, his chest rattling with the sound of a lung edema. He couldn't talk, couldn't move. He, too, was dying. Ben Yehuda asked a passing British climbing team to help him. He learned later they did.
Ben Yehuda soon lost the ability to rappel. He needed the rope loose, but too many people were on it, making it tight. Irmak slipped from Ben Yehuda's grip. Both men slid down the ice.
Irmak fell into an ice crack, dragging Ben Yehuda with him. The rope tangled around Ben Yehuda's legs, threatening to bury him in the ice crack as well. He used ice axes to dig them out, but it took precious time.
Eight hours after finding Irmak, the two men reached Camp 4. Ben Yehuda was dragging Irmak by then, barely able to stand.
But it wasn't over. Rescue helicopters can't reach above Camp 2 because the air is too thin.
After resting for a few hours and examining his frozen right hand, now swollen to the size of a baseball glove, Ben Yehuda took another 20 hours to get Irmak to Camp 2.
Approximately 328 feet from the camp, Ben Yehuda fainted in the snow. Other climbers found him, fully hypothermic, and put him in a tent. Without food or a stove, he lived off ice for more than 28 hours.
The next morning, Ben Yehuda awoke to someone shaking his tent. It was Irmak, who couldn't speak from his frostbitten face, but he looked at Ben Yehuda and his deformed hand.
"It was a moment of happiness, of anger, of many things together," Ben Yehuda said.
The two men required extensive treatment once they were airlifted out of Camp 2. Back in Israel, Ben Yehuda was treated for brain damage, lung problems and his frostbitten face and legs. Some operations were canceled or delayed because he'd lost so much weight. It would take him months to regain the 42 pounds he lost on Everest.
Doctors wanted to remove every finger but the thumb on his right hand, but Ben Yehuda wouldn't allow it. He received orthopedic and plastic surgeries instead.
He's kept in touch with Irmak, who suffered a brain edema and doesn't remember much of the rescue. Ben Yehuda has shown him photos that spurred his memory. Klorfine's body can be seen in one of them.
According to reporting by Outside Magazine, Irmak summited Everest this year.
The summit and the storm
Like Ben Yehuda, Jon Kedrowski and Sandra LeDuc waited for the crowd to thin out. They had prepared for years, and LeDuc wanted to tick Everest off her list of the "seven summits" -- the highest peak on each continent. Everest was No. 5.
Kedrowski had designs on a fast and light climb with a low flow of oxygen. Back in Denver, Tomer, the meteorologist, was blogging based on Kedrowski's texts, e-mails and satellite phone calls. LeDuc's brother was sending out tweets to her 60 followers.
