Yellowstone Lake, WY

5 of 15

Clear, deep, and cold, Yellowstone Lake is found in one of the world’s most geologically active areas, under the watch of the Beartooth and Absaroka mountains. More than 2 million visitors pour into the national park each summer, but winter could very well be the best time to see the lake; the bubbling geysers along the West Thumb shoreline appear as colorful cauldrons in the snow, steam rising eerily from the icy landscape. Indeed, Yellowstone Lake is typically frozen over for half the year.
