(Adapted from author's abstract.) In May 1974, an aerial survey of brown bear denning habitat was conducted in the Katmai area. A total of 232 dens were located, with the majority (70%) found on hillsides between 500 and 1,500 feet in elevation. South-facing slopes were most commonly selected by denning bears, with east-facing slopes second in importance. Dens were most often situated within or at the base of willow or alder patches. The largest concentrations of dens were found in the Naknek Lake area; specifically on Mt. Dumpling and Mt. LaGorce, along the Savonoski River, and along the foothills north of Lake Colville and Lake Grosvenor. One hundred seven dens were located within the boundaries of Katmai National Monument.
