A man walks with his dog on the frozen Lincoln Reflecting Pool in Washington, DC.

As the deep freeze lingers, residents skate and play hockey on frozen landmarks, including the Lincoln Reflecting Pool and Constitution Gardens Pond near the National Mall, while city crews continue clearing hardened snow and ice from streets and sidewalks.
