World-class climbers John Roskelley and Chris Kopczynski went to remote areas to ascend some of earth’s highest peaks. During these expeditions and other travels, they sought out new heights—and signatures. At the request of their mentor, Joe Collins, who encouraged the pair to climb when they were teens growing up in Spokane in the 1960s, the friends and longtime climbing partners asked some of mountaineering’s most celebrated adventurers to autograph books they authored or appeared in.
