Uulu the oldest polar bear in captivity at San Francisco Zoo & Gardens enjoyed a snow day today.

This morning, in honor of International Polar Bear Day, the zoo had 10 tons of snow and ice brought into Uulu's habitat as a special treat for the 35-year-old bear. The day was set aside globally to bring awareness about climate change in the Arctic and how it affects animals that inhabit the region.

The event attracted hundreds of spectators, as they watched the polar bear play like a cub in the snow. There were also lectures given by the zoo staff on climate change and caring for aging animals.

"We're so proud of the work our expert animal staff is doing to keep Uulu in the best health possible for her advanced age," said Tanya M. Peterson, President of the San Francisco Zoo & Gardens.

Uulu first arrived at the San Francisco Zoo & Garden in 1985 under rescue circumstances.
