Ok.. let me start off by saying that I completely stole this idea from a photographer (a university photography instructor, actually) I encountered while shooting the same scene in Acadia National Park in Maine this past May. While I took a few shots with natural light, he was assiduously shooting in black and white (or, at least shooting with black and white in mind for the final image), and using a flash to light the foreground. He said he was determined to shoot something that would not be considered a typical tourist photograph.
Here's one of my natural light shots from that evening (not an entry)

However, my curiosity piqued, I went back the following evening, and, again with my tripod, I scrambled out on to the rocks (a bit further out than his shooting location), and fired off a few shots with the SB-800. I did a manual exposure for the Head Light, and tried a few different flash settings for the rocks.
Sure, it's unnatural looking, but it was fun experimenting.
