Not the greatest shot of Yellowstone Falls, but this is the best I got on a miserable late May day in the park that showed us all kinds of weather in a few hours: foggy, sunny, drizzle, heavy rain, wind, snow and sleet! It's not so much that it was misty and cloudy. That would have been fine, but both times I went to the falls viewpoints, howling bitterly cold winds started blowing with rain making it difficult to stand there and shoot. Taken with Canon SX100 IS with an effective 168mm focal length. Wish I had a little wider shot to get more of the mist at the top. Thanks for looking.
