Rolando Garibotti, reporting in a post on SuperTopo:

Between the 12th and 16th of February, Tommy Caldwell and Alex Honnold completed the first ascent of the much discussed “Fitz Traverse”, climbing across the iconic ridge-line of Cerro Fitz Roy and its satellite peaks in southern Patagonia.

This ridge-line involves climbing Aguja Guillaumet, Aguja Mermoz, Cerro Fitz Roy, Aguja Poincenot, Aguja Rafael Juárez, Aguja Saint-Exúpery and Aguja de l’S.

In all they climbed across over five kilometers of ridge line, covering close to 4000 meters of vertical gain with difficulties to 7a (5.11d) C1 65 degrees. They simul-climbed much of the climb, dispatching 20-pitch sections such as Pilar Goretta in a mere three pitches.

Not bad for Honnold’s first visit to Patagonia.
