Caldwell and Jorgeson reached the final 11 pitches on Tuesday after working their way past some of the toughest stretches on the rock.

Since the warmth of the day caused their hands and feet to perspire, the two often started climbing at dusk. They used ropes and other tools to move back and forth between the pitches they were attempting to master and their campsite, perched high on the rock.

Jorgeson struggled for several days last week on difficult pitch 15, at one point being forced to rest for two days while the skin on his fingers healed after being ripped off by razor-sharp ledges.

Their attempt on El Capitan was closely watched in the climbing world and drew worldwide news headlines and attention on social media as they made progress toward the summit.

Caldwell, 36, who is sponsored by Patagonia and is one of National Geographic's "adventurers of the year" for 2015, conceived of the climb in 2007, the company said. Jorgeson spent five years preparing for the climb, his website said.
