The Atomic Explosion and Mushroom Fallout at SunsetThis day and evening I was in Yellowstone alone. I had just seen a grizzly bear and a black bear about 30 minutes before this shot, both of which are pretty rare to see. They went on their way and I was left in the middle of this area with just a few elk meandering a few hundred feet from me. I tried to not get overly "sucked into" the sunset, trying to remember those bears that were lurking about. The ground was pretty marshy here, so I was not in optimal conditions for running from a bear.from the blog at www.stuckincustoms.com
