Query: Great advanced skiing book and resource.

As far as I'm aware, no other book covers advanced ski technique. The DesLauriers cover catching air, jump turns for steep terrain and tight chutes, crud skiing, and a host of other advanced technique that is difficult to find any info on. The pictures in this book are breathtaking. They are also very informative and illustrate the written instruction. The book is well written and easy to understand. There are even short descriptions of great skiing around the world. And the book closes with an introduction to backcountry skiing. If you're looking for an intro book I would go with "Lito's Breakthrough On Skis". On the other hand, if you are an accomplished skier looking to learn advanced techniques, some of which are rarely taught, "Ski the Whole Mountain" is excellent.
