POLAR BEAR ON HOT DAY IN SAN DIEGO ZOO.
Polar bear at the San Diego Zoo beats the summer heat July 10, 2003 by
enjoying a winter wonderland. Animal keepers created the snow this morning
by blowing 18 tons of shaved ice into Polar Bear Plunge, the Zoo's summer
tundra habitat. The unseasonably icy treat stimulated play behavior in the
bears and is part of the Zoo's ongoing environmental enrichment program.
