At the end of last month, two skiers achieved an unprecedented feat: descending the summit of Yosemite National Park's iconic Half Dome into the valley below.
In 1865, a report declared that the rock formation — at more than 8,800 feet above sea level — was a path that "never will be trodden by human foot."
Since then, Half Dome has become a popular, but challenging, hike.
But on Feb. 21, Jason Torlano and Zach Milligan made the nearly 5,000-foot trek down on skis.
