For anybody with an interest in attempting to climb Denali's Cassin Ridge, here's a very high resolution image I created by combining several single frames of sections of the route. Apologies for the portions that are not quite sharp. With a 400mm lens sticking out of a plane window going nearly 100mph with temps well below 0 F, I was happy to just get the frames I needed to make this image. 1/1200 of a second may not have been fast enough with that focal length, or perhaps the autofocus was fighting the fierce wind.....
Enjoy!
