Yellowstone Upper Falls
Of the two major falls on the Yellowstone River, the Lower Falls are by far the more celebrated and photographed. The Upper Falls, however, are also quite impressive; they are not as high as the Lower Falls, but are quite wide and make quite a splash. (Funny, aren't I.)
In the background, up river from the falls, you can see the Chittenden Memorial Bridge, named for the park engineer who led the construction of the initial span in 1903. It provides access to both sides of the river and canyon.
