Ok,
It does look like a reflection on my side, but only on our left side of the photo and it's not a smooth reflection, meaning that it could be the reflection from a top layering of ice and frost. On the right side of the photo, same lower area, the frozen liquid or mud that clings to the elevation line looks denser, coarser and definitely not as 'reflective'. Of course, Justin could be right too in that they could be shadows, not reflections.
We need sharper images! *g*
