LEFT • Ian “i’Mac” McIntosh’s enthusiasm and strength in the mountains is infectious. He is a spine technician, and going on trips with him—like this one to Alaska’s Tordrillo Mountains in 2007—is like having a remote-control skier. He always hits the landing, with the finesse-meter pegged. (Teton Gravity Research/TGR) THIS PAGE • Erik Roner flashes a line in Haines, AK in 2009. I have always liked the “happy accident” helicopter blade in this image, and while the frame before got published, I feel this one tells a better story. And yes, I’m still a junkie for the open-door days when I was the drone. (TGR)
