Do grizzly bears still wander the San Juan Mountains of Colorado, where they have long been considered extinct? If so, can they elude the naturalists determined to prove that these bears, smarter than all other bears, survive in the mountain wilderness? Rick Bass, along with veteran grizzly expert Doug Peacock and biologist Dennis Sizemore, search for proof - a claw mark on a tree, a tuft of fur, bear tracks - and as they search an adventure unfolds that has as its mission the peaceful coexistence of humankind and the natural world. With the exhilarating insight his readers have come to expect, Rick Bass describes the dangers and clues on the trail of the grizzly, the mystery and beauty of the animal, and the courage, hope, and friendships at the heart of the search. The Lost Grizzlies is more than a foray into deep wilderness. It is, ultimately, as much about humans as it is about bears.
