From how many locations on Earth can someone walk one mile south, one mile
east, and one mile north and end up at their starting point?
Any point where the mile east takes you an exact number of times
around the globe. So, anywhere exactly one mile north of that, which
is a number of circles not far from the south pole.
It is my contention, completely unbacked by actual research, that if you find such a spot (heading a mile east takes you
an integral number of times around the pole), that there is not enough Earth left to walk a mile north so that you could
then turn-around a walk a mile south to get back to such a location.
