Mr. Griebel said Mr. Klein had climbed El Capitan — known as El Cap among climbers — more than 100 times. Mr. Wells had also climbed it many times, he said. El Capitan is “much bigger than anything around here, which is why he liked it,” Mr. Robinson said. They were doing this with a third person, a variation on an already rare technique that is “inherently riskier” than regular climbing, Mr. Robinson said. The third person, who was not identified by the National Park Service, was on a separate rope and anchor, and not securely attached to the same system being used by Mr. Wells or Mr. Klein, according to Mr. Robinson, and was unharmed.
