This is what you see after you leave a Princess cruise ship docked at Whittier, Alaska, and get on a train for the Princess Wilderness Lodges. This video was shot over a period of two days between Whittier and Denali National Park on the Alaska railroad.
Note the cottonwood trees were tossing their seeds in to the wind, making it almost appear like it was snowing... except this was in the middle of summer! You can notice this beginning at about one minute in to the video. It is especially noticeable in the scene at two minutes in to the video.
