Exploration stations are temporary exhibits set up in the Karner Classroom. The topics change about every 3 months. The current topic is The Subnivean Zone – Go Below The Snow which will be installed through March. The subnivean zone is the area between the surface of the snow and the ground. Many animals actually depend on snow for protection and warmth during the winter months. Come tunnel through the indoor subnivean zone, make snowflakes and learn more about animals in winter!
