Clara held one hand tight, then released the other, reaching further, needing to eventually reach the edge of the overhang. She found a hold then repeated the process. If there wasn’t a sufficient handhold, Clara would use her rock climbing claw to create one. The further she climbed, the more ice there was to contend with. This naturally made each successive grasp a more difficult proposition than the last.
Her arms burned and her fingers were going numb, but still she climbed. Finally she reached the edge of the overhang, claw embedded in ice and rock, fingers bloodied and bruised.
