On most mornings, daybreak happens in the background. Some people sleep through it, others rush through their morning routine without noticing the moment that the sun rises over the horizon. See what you've missed as Discovery HD presents the premiere of Sunrise Earth. This special presentation - exclusive to Discovery HD - features three one-hour specials capturing the drama and beauty of daybreak as never before. Produced in stunning High Definition, each episode of Sunrise Earth chronicles one continuous hour of dawn - without narration, music, or quick edits - in some of the most scenic locations on Earth. Explore the tranquility and restorative power of the natural world as Sunrise Earth moves from darkness to light. The three episodes featured in the evening's event are "Katmai Bears, Alaska," a charming look at bear cubs awakening after hibernation; "Greatest Hits East," a compilation of the most stunning sunrise locations along the east coast of North America; and "Greatest Hits West," a "best of" look at the most picturesque dawns in the American west.

Episodes highlights include:

Sunrise Earth: "Katmai Bears, Alaska"They've had seven months of sleep, but now the world's largest population of unhunted brown bears is ready for the sun. They begin the early morning in the meadow, playing and grazing on the high protein remnants from the tide. A three-year-old cub searches for Mom as the sun rises. When the tide drops, clams and the first tasty salmon of the season are revealed. As the bears stake out their spot on the beach, two males posture for status, a young cub nurses and adolescents chase each other for kilometres.

Sunrise Earth: "Greatest Hits East"The sun hits the Atlantic seaboard five hours after the western coast of Europe, and a wide range of habitats begin the shift from the cool nocturnal stillness of the night to the warmth and activity of the day. This episode captures the transition of dawn, from the sub-tropical ecosystem of the Everglades and the northern lakes of New England, to the very first light atop Cadillac Mountain in Maine and the sabal palms of the Gulf of Mexico. These are great sunrise moments in nearly a dozen morning ecosystems of the east.

Sunrise Earth: "Greatest Hits West"Crossing the North American continent in just four hours, daybreak settles on the Great Plains, the Rocky Mountains, the coastal ranges and beaches of California before departing the western shore. Witness the sunlit beauty of Yellowstone geysers, herds of horses and bison on the open range, the spectacular lighting of the Teton Range. Then in California, see the sun rise above the massive sequoia, tule elk, a rainbow of wildflowers, the Yosemite Valley and elephant seals on the beach. Featuring nearly a dozen locales, these are the greatest sunrises in the American west.
