This is wrong, he free climbed the dawn wall but definitely did not free solo it. Every photo from that article shows him climbing with ropes and google more into it he definitely didn't free solo that face of El Cap.

The article is wrong. You can clearly see Adams lead line in the picture in the article.

Adam on The Dawn Wall was super impressive - iirc, he sent the route in a single ground-up push or something like that, when it took Tommy, like, 8 years to establish the route. But he def didn't solo it.
