Honnold soloed up the Original Route on Rainbow Walls, a 300m 5.12b, then on the same day he went on to solo the route Prince of Darkness, a 220m 5.10c and down solo Wild Turkeys to get back to the floor after his ascent of Prince...
Honnold commented that the Original Route was "...really airy. There are stemming corners that let you look straight down. Perfect edges, flat rails make for cool climbing, but a couple moves seemed a little sketchy..."
Honnold made a visit to the UK back in 2008 when he made several hard ascents including an onsight solo of the classic E5 finger crack of London Wall at Millstone.
