I got a tip from Johan at work about an interesting book, one that deals with underground wonders. The book is Underland by Robert MacFarlane. I don't really know yet what's inside, but there was a recommendation in New York Times, that can't be bad :-)
The article is here and you can order the book in Finland here and from the publisher here.

"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.
