The boulders you can see in the this photograph were most likely deposited by glaciers quite some time ago. Boulders like these are pretty common throughout the glacially carved valleys and meadows in Yellowstone National Park.
A friend and I hiked a 6.6 mile loop in Shenandoah National Park, specifically to get photos of waterfalls. Our hike passed three significant falls but this little cascade at the top of one of them yielded my favorite photo of the day. It isn’t very dramatic and I think that’s what I like about it. The image makes me think of a quiet, little, almost secret spot, you could visit to get away from the world for a little while.
