American West Mountain

In 1804, John Colter set out with Meriwether Lewis and William Clark on the first US expedition to traverse the North American continent. During the 28-month ordeal, Colter served as a hunter and scout, and honed his survival skills on the western frontier. But when the journey was over, Colter stayed behind. He spent two more years trekking alone through dangerous and unfamiliar territory, charting some of the West's most treasured landmarks.

The grizzly is one of North America's few remaining large predators. Their range is diminished, but they're spreading across the West again. Descending into valleys where once they were king, bears find the landscape they'd known for eons utterly changed by the new most dominant animal: humans. In searing detail, award-winning writer, Montana rancher, and conservationist Bryce Andrews tells us about one such grizzly. Millie is a typical mother: strong, cunning, fiercely protective of her cubs. But raising those cubs becomes ever harder as the climate warms and people crowd the valleys.
