Marty’s photo of the day #2607: Flying north over the Brooks Range in Alaska is one of the most dangerous flights anywhere. That’s because the tiny airplanes pilots use to land on the tundra in the Arctic National Wildlife Refuge barely have enough power to fight the wind blowing south off the Arctic Ocean.

I took this photo on the return flight, which isn’t as dangerous. Even so, once in a while a gust of wind would give us a push, which felt disorienting because it was like being on a surfboard and having an unexpected wave come up behind you to give you a lift.
