Maureen Beck may have been born missing her lower left arm, but that hasn’t stopped her from going hard. She takes whippers on 5.12 and crushes overhanging boulders, while shot-gunning beers. But she is not here to be your inspiration. “People say, ‘Look, a one-armed climber, now I have no excuses.’ I’m like, dude, you never had any excuses in the first place.” Maureen is here to crush the gnar — with one bloody stump helping her get to the top.
