I’m not a climber, but this is impressive because she had to shovel snow to work on this, and she used duct tape. And it may be one of the most difficult traditional routes ever.
From Alpinist:
Of Meltdown, she said: “I had to work harder on this climb than on any other… I think I was a little stubborn on this one. Most anyone else would have left (because of the winter season and difficulty), but I think the shoveling helped my climbing. It makes your back strong.”
Tenuous moves combined with “pretty serious fall potential” persuaded Rodden to develop a special gear system. Instead of clipping gear to her harness, she connected three vital cams with duct tape. This system allowed her to rip them off her harness easily, saving time and energy in the most desperate situations.
