We spent almost 2 weeks at Yellowstone National Park! Lots to see here!
Beartooth Mountains in the Northeast section.
The Grand Canyon of the Yellowstone. Quite a sight! Unfortunately you have to take pretty steep trails to get real good pictures. I think these will give you a good idea of how impressive this place is!
Lower Falls 309 ft.
Upper Falls 109 ft
Tower Falls are a good example of a Hanging Valley, where a small glacier gave way to a larger one.
