Where Do Bears Go To Hibernate?

Bears hibernate during the winter in large spaces among the roots of trees or in holes they've dug beneath the trees. Sometimes bears hibernate under a large rock or in a half-closed hollow that has been formed by a fallen tree. In hibernation an animal's body temperature drops to the level of the surrounding temperature and the animal becomes almost completely inactive. Bears are not true hibernators. More precisely, they become dormant in the winter. As they sleep their body temperature seldom goes below 88 degree Fahrenheit. (31.1 degree Celsius.). They may occasionally wake up and move about, and the females nurse their cubs.
