Cold Snap Denver Zoo
Lee the polar bear roams his pen, at Denver Zoo, which was closed to the public due to extreme cold, in Denver Thursday Dec. 5, 2013. A wintry storm pushing through the western half of the country has brought bitterly cold temperatures that prompted safety warnings for residents in the Rockies and threatened crops as far south as California.
