This evening a little before 7 PM a neighbor called us to ask if we were seeing the same strange light on the peak of Rattlesnake Island that they were. We hadn't noticed it, so we went outside to look. Sure enough, right at the peak of the highest part of Rattlesnake was a light. We got out our spotting scope and were amazed to see a perfect triangle comprised of a number of individual lights. I mounted my camera on a tripod and zoomed out to the maximum focal length to see if I could get a picture of the light. The photo isn't nearly as sharp and clear as what we saw through the spotting scope, but I thought it was worth posting here to see if anyone has the slightest idea what it could be! We believe that electrical power is out over the entire island, so whatever this light is, it must be either powered by a generator or a battery. And who would climb to the highest peak on Rattlesnake in the winter to erect a triangular light like this, resembling a Christmas tree? Anyone have any ideas?
