A must-read on these magnificent but sometimes deadly creatures—thoroughly revised, expanded, and updated  Much has changed in the twelve years since Mark of the Grizzly was first published. DNA science has dramatically altered how bears are studied and how attacks are investigated. Increasing bear populations have led to more bear/human encounters—some fatal—and grizzlies are expanding their territory in vast reaches of the West. This new edition includes a thorough revision of existing material in light of modern investigative techniques and changes in bear populations, and at least five new chapters that cover:  - The recent spate of attacks around such places as Yellowstone National Park and Anchorage, Alaska, which have generated national headlines. - The apparent link between the increased popularity of mountain biking and trail running and bear attacks. Are such sports advisable in bear country? - Expanding bear populations. Bears have recently been found on the prairies of Montana and Wyoming, far from their normal mountain locales. -“Bear Men.” People who get too close to bears, and as a result, meet their maker literally in the jaws of the great beasts. The book includes a profile of Timothy Treadwell, subject of the movie Grizzly Man.
