Chris Morgan explores the world of black bears caught in the crossroads of urban development in Anchorage and the wilderness. This is a new normal for bears and for their human neighbors. Some bears are so comfortable living in urban surroundings that their primary habitat is a golf course. In residential areas, bears frequently raid garbage bins and birdfeeders for easy snacks. But these behaviors are less than ideal for bears and residents alike. Morgan heads north out of Anchorage to Denali National Park, where the mountains loom over treeless plains and bears get by on a diet of thousands of berries a day. The grizzlies share the enormous park with foxes, wolves and moose — and with one intrepid bear biologist and his team. Morgan continues his journey north on a bone-shaking, 610-mile motorcycle journey from Denali to Prudhoe Bay along the only Alaskan highway to reach the Arctic. Prudhoe Bay, a once pristine area at the edge of the Arctic Ocean, has been changed forever by the oil industry.
