We are very sad to announce that “Snow,” the Zoo’s 17 year-old polar bear, has passed away on Monday, September 3rd. She was discovered first thing in the morning by her Zoo Keeper. She was in her normal sleeping position and location, with no signs of trauma. The Zoo’s veterinarian indicated that although she had chronic health issues, she was improving. We are proud of everything the Zoo staff did to provide Snow with a wonderful quality of life in Tucson. She will be missed.
