PEACH, I think you're off base. PORVENIR got its start as a gold mining town. Also, the terrain slopes "up to the base of Cordillera de Darwin," which is a high mountain range. There will be plenty of trees and non-flat terrain nearby. I just revved up Google Earth for a look around that part of Tierra del Fuego. It is cloudy directly over Porvenir right now, but I can confirm lots of mountainous terrain nearby.
