The expedition was also close to running out of food and time on their climbing permits, factors that led to the decision to end the attempt.
Climber Stephen Martin, 42, isn't calling it defeat; he calls his encounter with Mount McKinley a tie. "I took everything it could give me, we just ran out of time," he said Tuesday by telephone from his home in Phoenix.
There were two double leg amputees and two above-the-knee amputees on the climb. All were wounded in wars from Vietnam to Afghanistan. The climb was organized by Disabled Sports USA and its Warfighter Sports program.
"I can say it is absolutely the most nerve-racking, exciting, exhausting, challenging experience I've ever had," said Kirk Bauer, a climber who is also the CEO of Disabled Sports USA. The Baltimore man lost a leg to a grenade in Vietnam in 1969.
The climb was intended to inspire others who have been or will be wounded in wars that they can still lead active lives.
Even though they didn't summit Mount McKinley he hopes the attempt still sends a strong message to the wounded and disabled to "chose to drive forward to success and not to accept the disability as something that defeats them."
There were worries about what the cold might do to the prosthetics the men were using to climb.
Bauer said they held up surprisingly well. The single-leg amputees needed to constantly recharge batteries that run computers to aid the knee unit since the cold on the mountain zapped their power quickly.
They even brought along solar charges, but were worried how they might act. "When the sun came out, it was so bright that the solar chargers went crazy," Bauer said.
One problem, which was expected, were the pressure sores and abrasions from where the men's artificial limbs met their prosthetics, exacerbated by carrying backpacks weighing up to 70 pounds and pulling a sled with another 60 pounds of gear.
"They take a real beating," Bauer said of the legs.
The group actually made it to the 15,500 foot level before they turned around. It was on the descent back to camp at 14,200 feet when Martin injured himself when his foot got jammed in a hole and was severely twisted.
He tried to sleep off the injury, but could hardly walk the next day.
Guides put him into a large sled and led him down the mountain.
Martin, a retired Army corporal who went back to Afghanistan as a contractor, lost both his legs in a roadside bomb attack.
He said the first day in the sled, going from 14,200 feet to 11,000 feet, was "hell ... terrifying because the conditions were so bad." The snow was 5-to-8 feet deep in spots, and the guide leading him kept sinking into the snow, and they were two feet from the ledge of a cliff. He was in the sled, using his ski poles to help push along on the treacherous part of the mountain, which has claimed six lives this year.
But from 11,000 feet down, he said they were just flying down and said it was "so much fun," reaching rest camps two-to-three hours ahead of everyone else.
Jesse Acosta, 34, the only team member will all his limbs, suffered permanent damage to his back, hip, leg and arm from a roadside bomb in Iraq.
The most difficult part of the climb was having to accept there were a number of elements outside their control, like weather, said Acosta, an Austin, Texas, native working on Wall Street.
"There's a stinging sensation about not making it, but I think we all walked away saying we put in everything we could," Acosta said.
The other members of the team were Marine Capt. David Borden, 31, of Hanover, Pa., the only active duty military member, and Ret. Army Sgt. Neil Duncan, 29, of Denver, the other double amputee.
Bauer, who like Acosta and Duncan, has climbed Tanzania's 19,336-foot Mount Kilimanjaro, said his climbing days are over after the attempt to climb Mount McKinley.
At 64, Bauer is the oldest of the group. He said the younger men, "all said they want to beat this tiger, so stay tuned."
There are no doubts for Martin, who wants to return next year. "I'm going to climb that mountain. I know I can do it."
Acosta isn't counting any of them out, and said there's an absolute desire to return to Mount McKinley.
"I think we're all accepting the fact the mountain isn't going away, and we still have a lot of years left on us, Kirk included, so we'll see where it goes," Acosta said.
