There’s no easy path to where the Earth’s axis of rotation meets its surface.
One such path from Denver goes like this: Denver to Dallas to London to Oslo to Tromso to Longyearbyen to base camp. From there, one must board a helicopter to the 89th parallel and ski north.
How far? Well, that depends. Sean Swarner had to ski nearly 80 miles to reach the North Pole in early April. That journey over a polar ice cap completed Swarner’s Explorer’s Grand Slam, which he says sounds like a Denny’s meal.
It’s a little more impressive than that.
