Author and naturalist David Rockwell explains the evolution of the park's geology from the erosion of Australian mountains more than a billion years ago to the glaciers that gave Glacier National Park its distinctive landscape. He explores the natural history of the plants and animals of the park's six distinct regions. You'll learn about the park's greatest predators, grizzly bears, mountain lions, and wolves, and about their complex relationship with their prey. The result is a fascinating and intimate portrait of one of the world's last truly wild places.
