The last time I skied into Avalanche Pass, on a gorgeous, powdery day, we passed approximately 75 people trudging along on expensive high-tech snowshoes. With these on your feet you can abolish friction. Except for Jim Tucker's webfoot racers out at Paul Smith's, though, snowshoeing is not a sport, no matter how many Mountain Dew commercials try to convince you otherwise.
Snowshoes are transport.
Skis, cross-country skis, are magic. The lack of trails in many of the Wild Forests and Wildernesses, which permits the glory of summer bushwhacking, makes skiing difficult except in the deepest snows, when you can cut through any hardwood glade. This list of 50 gems, though, should give several winter's worth of day trips for any Adirondacker. They are widely distributed throughout the Park, with particularly fine coverage of the Blue Mountain Lake and Pharaoh Lake areas. But that makes for a light book to tote, and on a bitter day with the wind whipping across Wilcox Lake, you may not want to read great volumes anyhow.
