Erika and I went down to the tetons on a warm and sunny weekend in January. We had great weather (as you can see) and saw several Moose during our travels.

View of tetons from inside the new visitor center at Moose. The cool thing in this pix is the shadow of the roof on the snow. The visitor center roof as several "peaks" to try to be like the peaks of the Tetons - the sun angle was perfect this morning and I caught those shadows in the snow
With the warm days and cold nights there was a lot of hoar frost on the snow - I didnt capture how much it sparkles in the sun in this picture, but its still pretty.
