Late last summer, the Kansas City Zoo opened its newest exhibit, Polar Bear Passage, to a host of anxious zoo patrons.  Nakita, a 3 -year-old, 750-pound polar bear, made the exhibit his new home.  The bear has quickly become a star attraction at the over 100-year-old zoo. The exhibit was designed by international zoo design/architectural firm PGAV, built by local general contractor Barsto Construction and exhibit contractor COST of Wisconsin, Inc.  The project encompasses over 18,000 square feet of glacial carved rock work with snow and ice caps, which provide the exhibit with a realistic back drop. Several rock peaks rise to over 25 feet tall. The simulated rock, ice and snow were all constructed by artisans based upon photographic references and scale model. A scenic waterfall provides Nakita a cool mist during warm summer days.  Guests can view the entire exhibit from multiple viewing angles in a climate controlled building, including an area for under water viewing.
