“When I first had the idea to climb Denali in 2013, an old ranger took one look at me and declared I would never make it to the top,” said Ken Karstens, Harry Karstens’ great-grandson and of the lineage of the climb’s Karstens Ridge. “He told me to forget about the whole thing, but I found motivation in the old Ranger’s words, which was his intention, and, now, I can’t think of a better time to remember Charles Sheldon and what one man was able to do for Denali.”
