Watching the Yellowstone River tumble over Upper Falls in the Grand Canyon of Yellowstone is quite a sight to behold. The place is also called The Brink, and it feels like you’re on the brink when you’re leaning out over the stone wall to photograph the roiling water as the sunlight dances over it. It’s a place you have to shout to be heard over the roar of the falling water and the beauty of the place is unforgettable.
