Autumn at its peak with the Tetons in the background. A hint of smoke in the air from a forest fire many many miles away in Yellowstone. The Snake River's Oxbow Bend in the foreground.
This is at sunrise, right as the sun is lighting the trees. There is a light amount of smoke over the mountains in the rear. The smoke is from a fire in the eastern part of Yellowstone. This was taken at the end of September 2009, at the peak of fall color for the trees at Oxbow Bend.
