Before the first person climbed to the top of the Half Dome in 1875, it was considered impossible to do. And then a man named George Anderson made it all the way to the top by drilling into the rock so that he could anchor bolts along the way to help him climb. . A set of cables now line the last, almost-vertical four hundred feet of the trail, anchored into the same holes Anderson drilled in the 19th century. His climb has enabled many others to accomplish the same test of strength.
