User blog comment:Swiss Ninja/South Pole City is South/@comment-1024726-20100206231348

Zapwire is the only person on this blog post who knows anything about Antarctic cartography.

The USA, being located at the bottom of the world, doesn't use a grid system in their maps. Instead, their system goes like this:

South Pole City is marked as a dot on a circular map. Going outwards from this dot in any direction is heading north. Heading towards this dot is south. Traveling along a circle on the map (that is centered on SPC) in the clockwise direction is heading east, while going the other way around is heading west.

This is simply because SPC is on the South Pole, which is as far south as it gets. Yes, it's confusing, but there's no other choice but for us to work in these conditions.
