Among the small cadre of youngsters climbing at grades in the 5.14 range (strength level: adult bonobo monkey) Mirko Caballero stands out for his relaxed yet mature approach to his craft. This week Mirko is in Bishop, California, home to some of the most majestic freestanding boulders in the world. It is a playground of classic problems, especially considering the highballs, and Mirko is sniffing around some of the V13s.
