Season 1

The snowy crests of the Cascades conceal the most active volcanoes in the continental United States. Foxes thrive on their slopes, tailed frogs mate in rocky streams, and pine martens hunt in the alpine forests. But the mountains have a violent past and an uncertain future.

Coastal California is home to one of the world’s oldest and most iconic residents—the redwoods. Thousands of convergent ladybugs use their roots to mate and hibernate while the wandering salamander can spend it’s entire life in the redwood canopy.

The incredible force of glaciers shaped some of North America’s most breathtaking landscapes, creating a home for the wildlife living within them. The delicate environment that so many animals from the mighty grizzly bear to the nimble pika call home dwindles away with the ever-heating sun.

From bears to beetles and bighorn sheep to mountain lions, life in the Colorado Rocky Mountain range is as resilient as it’s wildlife, regardless of whether they're big or small.

Bus-sized humpback whales pause their migration north to snack on anchovy swarms. Elephant seals duel for control of the beach... and the mating rights that follow. The Golden Coast is a wild land, from its tallest hills to its deep, underwater canyons.
