Looks like snow to me. From the Department of Interior:
Bering land bridge in autumn
September 23, 2013World and U.S. history classes should be long past this point, but the photo just recently surfaced:

From America’s Outdoors: Bering Land Bridge National Preserve – Gone are the shockingly bright pinks, yellows and purples of summer, replaced by deeper and darker reds, yellows, greens and the beginnings of brown, all of equal vibrancy and beauty. And soon, as the 34 degree weather and diminishing daylight would lead us to believe, a blanket of white will fall upon the landscape. Enjoy the change of seasons wherever you may be!
Bering Land Bridge National Preserve? Did you even know there was such a thing? Part of our public lands, your tax dollars at work.
Not a place for a Sunday drive. There are no roads to get to the place. For students, this site offers a lot of photos and interesting stuff for projects in history (human migrations) and geography (land forms, lava flows, migration routes, wilderness).
