When we traveled out to Yellowstone, back in 2007, it was fairly warm that year. Most of the snow was gone except from the higher elevations. When we woke up, on the morning that we were leaving to come home, we found everything coated with a fresh blanket of snow. On our way out of the park we stopped to take this shot. As you can see much of the snow had already melted in the couple of hours it took to get from West Yellowstone to Swan Lake Flatts. On our 2008 trip there was quite a bit of snow still covering the ground through out the park.
