It’s that time of year in Alaska when the gorgeous fall colors come out at Serpentine Hot Springs in 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. Enjoy the change of seasons wherever you may be! Photo by Katie Cullen, National Park Service. Posted on Tumblr by the US Department of the Interior, 9/17/16.
