I was recently in Alaska doing aerial photography of the Alaska Range to supply Denali National Park with a larger image library as a resource for climbers and rescuers. This photo is of the West Buttress Route on Denali taken from 24,000 feet in a Cessna 206. I had O2 for the flight, but even with o2, heading to 24K unacclimatized is a wild experience; I don't remember much from this flight! Thanks to the best photography shop in the Bay Area, Keeble and Schuchat, for their support of the project. It was their Canon 1ds Mark III and 24-105 lens that made this photo - one of my favorites from the shoot.
