A giant polar bear was spotted walking down Constitution Ave. on Capitol Hill in Washington DC, but it didn't escape from the zoo. Supporters of the Arctic National Wildlife Refuge, calling themselves the Alaska Wilderness League, gathered with Arctic animal mascots and this large-scale, two-person polar bear puppet named Snowflake – as a visual representation of the wildlife that begin their lives on the Arctic Refuge and its Coastal Plain on September 28, 2010. The Arctic Refuge is a national treasure and one of our last remaining great wild places – it provides crucial denning habitat for the endangered polar bear, and breeding grounds for numerous species of birds, as well caribou, muskoxen, wolves, grizzly bears, Dall sheep, and many other species. This year marks the 50th anniversary of the refuge. (Photo by Jeff Malet) - Jeff Malet Photography in Action
