From a CBS 60 Minutes video about Alex Honnold. Clicking HERE will start the CBS video report at the point they show a brief clip of Honnold free-soloing this north face of Half Dome (that means without a rope, tools or harness of any kind).
The photo of Half Dome (SX10 IS) was taken from another meadow that Herb showed us on Day 2 not accessible to cars. The trees at the top-right give an idea of the size of that area.
