Book excerpt: "In 1925, Paul Adams was appointed custodian of Mount Le Conte, the third-highest peak of the Great Smoky Mountains National Park. His job was to welcome tourists, give guided tours, and establish a camp that would become known as LeConte Lodge, which still stands in what has become America's most popular national park. Adams had everything he needed for the job: a passion for the outdoors, a love of hiking, a desire to preserve the native habitat while welcoming visitors, and the companionship of a remarkable dog. During his time on the mountains, Adams trained Smoky Jack to be a pack-dog -- not just carrying supplies but actually making the four-hour trip to the store in Gatlinburg and back alone. Throughout Smoky Jack, readers gain a unique glimpse into the early days of the Great Smoky Mountains region during the decade before it was name[d] a national park in 1934. Adams describes the trials and triumphs he and the indomitable German shepherd faced as they exemplified the ancient relationship between man and dog on Mount Le Conte, building trails, guiding visitors, and making a life in nature." -- Provided by publisher.
