Pirmin Bertle proposes 9a testpiece in Piedra Parada, Patagonia
German climber Pirmin Bertle has made the first ascent of 'Azul es el cielo de los ciegos' at Piedra Parada in Argentine Patagonia. Graded 9a, this route may well be the hardest sport climb in South America.
As previously reported, German climber Pirmin Bertle is currently touring Patagonia with his young family and after having made the first ascent of Dorotea at Puerto Natales - possibly the hardest boulder problem in South America - he now checks in with what might well be the hardest sport climb on the continent.
Located at Piedra Parada in Argentina, the route was an old project that Bertle freed after 30 attempts. The line is called Azul es el cielo de los ciegos (Blue is the sky of the blind), and boasts a 7c+ that leads to a bouldery 8B finish.
