Yellowstone National Park is remarkable ... in winter, it is just magica !
Contrast between the frozen ground covered with snowand ice and the geysers, hot springs and bubbling or steaming cauldrons of mud. Winter reveals more easily the wildlife that inhabit the park : foxes and coyotes hunt in deep snow, bison frequent the hottest geothermal areas to find their food, Wolves come in packs in the moonlight.
