Well there was the Squamish Buttress all free to the top :-D but, yeah, not to put too fine a point on it, UWall was the first of the old big aid lines to go free. And quite a few folks said it wouldn't go.
Anders can confirm the date for certain :-D but I 'm pretty sure it was the summer of 1982.
James Lucas So odd. I drove to Moonlight and talked to Alex and he had soloed. He soloed the Phoenix and Cosmic Debris...all my projects. today I climbed on the UWall and saw @alexhonnold On the way down. In the shade, just below the second power line, @alexhonnold solos the U-Wall. I took a picture of @smashits at the same spot a few hours earlier.
I don't know. He was did that interview down in Boulder right after he left Squamish. He was talking about the 290 pitches he did at Squamish for his 29th birthday. Most of it sounded pretty social for him. Lots on the Apron I think, no mention of U Wall.
