Boulder's adaptive-focused Paradox Sports is behind it, and the veterans are nothing short of amazing.
They recently trekked up Wyoming's Grand Teton to mark Sept. 11. In 2013, their goal is Mount Everest.
Air Force veteran Chad Jukes is one of the members of the group. He lost his right leg in Iraq.
"The climb was really an amazing experience," Jukes said. "I had the opportunity to go out with a number of other disabled veterans and climb one of the most beautiful mountains in the United States. In order to commemorate the tragedy that occurred [on Sept. 11]."
One of the more moving moments was when the veterans played Taps at the summit of the Grand Teton.
"It was really incredible to be able to go up there and be able to play Taps," Jukes said. "To be able to honor the people who lost their lives on that tragic day."
Jukes also talked about their Everest plan.
"I'm going to go to Nepal in May of  with a group of veterans including mainly Air Force service members ... called USAF Seven Summit," Jukes said. "They have already summited the tallest peaks on the other six continents and Asia is all that's left."
