During the mid-1970s the extraordinarily dangerous style of free solo climbing emerged in the collective practice of a small community of “Stonemaster” climbers actively developing new climbing routes and the new “free” style of roped climbing in what is now Joshua Tree National Park, California. While its emergence might be interpreted as an affectively-driven, macho embodied social semiotic or ethnomotricity, in actuality the evolution of free soloing in the case of Stonemaster-era climbing at Joshua Tree may be more accurately understood (...) as the logical consequence of an intensive regime of practice in which climbers developed a near absolute bodily familiarity with certain climbing routes. Eventually, the reasonableness of climbing with little and even no protection on a subset of these routes became self-evident and conventional. Free soloing, in the semiotic perspective of the later Peirce, manifested as a Normal Logical Interpretant in the Joshua Tree landscape. It embodied the living definition of self-controlled conduct, and the Symbols it cultivated testified persuasively to the growth of a creative corporeal intelligence actualizing near absolute degrees of free will.
