There are Hundreds of thousands of penguins there!
Rockhoppers, Maccaronis, Kings, Gentoos, Magellanics and the odd stray, erect crested. Oh and half a million black browed albatrosses!
Landmines placed by the Argentinians... soon to be removed under the international land mine clearance despite the fact that all the mine fields are marked and pose no danger to anyone.... even sheep may safely graze!
Geocaches - Probably local placements.
