Capping an extended bike-and-climb journey from Colorado to British Columbia and a sail up to Petersburg, Alaska, Tommy Caldwell and Alex Honnold made a one-day traverse of the Devils Thumb group. The Diablo Traverse, pioneered by Colin Haley and Mikey Schaefer in August 2010, ascends the two Witch’s Tits spires, then crosses over the twin Cat’s Ears to summit Devils Thumb by its west buttress. Haley and Schaefer completed the traverse over three days at 5.10 A2.

Honnold posted that he and Caldwell spent about 11.5 hours on the climbing portions of the traverse, simul-climbing most or all of the way, at maximum difficulty of about 5.11. Their round trip from high camp was about 17 hours.
