It was October 2017, and Alex Doria and Jonathan Wachtel were starting up a dream climb: the Regular Northwest Face of Half Dome, high over Yosemite Valley. Alex was in the lead on the third pitch, and he felt good. Too good, as it turned out. He ran it out a long way between protection, and just as he was getting ready to place his next piece, he lost his balance and fell. Alex, Jonathan, and Ashley discuss what happened next and the lessons they learned.
