Q. What should visitors expect from Yellowstone in winter?
A. An incredible diversity of winter weather, from severe, howling blizzards to deeply cold days with brilliant blue skies. Also, an overwhelming sense of peace, solitude, and beauty. Just about all the park's roads are closed, and the relatively few visitors can only get around on skis, snowshoes, snowmobiles, or snowcoaches.
Q. Must-see sights in winter?
A. The famous geysers and hot springs are extraordinary, especially with the proximity of the big animals like buffalo and elk. And seeing Old Faithful erupt on a cold day is incredible. The plume of steam looks like a giant head of cauliflower. There's a fallout of crystals that creates a scene like a surreal crystalline desert.
