A VERY crisp winter morning in Montana. This lone bison stands very still to conserve its energy on this 32 below zero morning. The tree in the background is covered in ice from thermal steam that froze solid on its branches. See which 12 elite survivalists can survive 14 days in the sub-freezing Rocky Mountains of Montana on #NakedandAfraid XL: Frozen tonight at 8P on Discovery and @discoveryplus.
