What is real wilderness? During a week-long visit to the Brooks River in Alaska's Katmai National Park, noted naturalist and master storyteller Paul Schullery strives to answer that question.

Environmentalists and the timber industry do not often collaborate, but in the years immediately following gray wolf reintroduction in the interior American West, a plan to reintroduce grizzly bears to the Selway-Bitterroot Wilderness of Idaho and Montana brought these odd bedfellows together. The partnership won praise from diverse interests across the country and in 2000 the U.S. Fish and Wildlife Service approved a plan for reintroduction.

Dax explores the political, cultural, and social forces at work in the West and around the country that gave rise to this innovative plan but ...
