More information can be found from the show cave website and Wikipedia.

"Mongolia is kind of close, right? Story about an attempt to ski everywhere in the world where there's snow. And in some places where there isn't. On and off-piste skiing on all continents, skiing into craters of live volcanoes, climbing, photography, and travel." The Planetskier blog focuses on skiing, caving, climbing, biking, flying, sauna, and swimming adventures around the world. See the other Planetskier blog articles about skiing, caving, urban exploration, climbing, cycling, flying, swimming, and saunas.
