Bo led the way on foot now, with Scratch’s lasso tied around his chest under his arms in case he fell. He made his way carefully, sliding his feet along the ground through the snow. The flakes stung his face, and he knew that he and the other men risked frostbite on any exposed skin. After an unknowable time, Bo bumped into something hard and unyielding. He tipped his head back and saw something dark looming over him. Resting his gloved hands on the surface, he explored it until he was convinced it was a huge slab of rock. If they could get on the side of the rock where it blocked the wind, they might be able to build a fire and thaw out a little. Bo worked his way along the rock. For all he knew, it was a cliff that ran for miles. But luck was with him, and after only a few yards he felt the surface curving under his hands. He followed it, and gradually the wind died down as the rock blocked the icy gusts. Bo kept moving until he couldn’t feel the wind at all. He tugged on the rope to signal Scratch that the rest of the group should follow him.
