The South Shetland Islands, really part of Antarctica, parallel the west coast of the Antarctic Peninsula as it stretches unsuccessfully toward to the southern tip of South America.
Sometimes the light is good there, as in this image from the South Shetlands near (but not at) Half Moon Island.
(You shouldn't care that I also ran out onto the deck for this light in shirtsleeves going "Oh my goodness!", but I did, so there it is.)
