The SEST (Swedish ESO Submillimetre Telescope).

I have no idea what this dog was called, but he/she/it accompanied us on our afternoon walk to see the petroglyphs. It spent the rest of the week trying to eat our legs.

As you can hopefully gauge from this photo, it's a couple of miles or so from the telescopes to the petroglyphs and they're certainly not easy to find without directions.
