I love these mountain pools in Shenandoah National Park. This one is downstream from Dark Hollow Falls but you can find scenes like this throughout the park.

When I reached the upper falls on the Doyles River in Shenandoah National Park, the lighting was horrible. The foreground and most of the photo above and to the left of the falls were bathed in bright, direct sunlight. The falls and most of the photo to the right of them were in dark shadow. So I bracketed like crazy and combined two of the resulting photos to produce this HDR image of the scene.
