The Alaska Peninsula is a cloud-cloaked land of active volcanoes, rolling tundra and the greatest concentration of the largest bears on earth. The writings of naturalist Loren Eiseley inspire this filmic essay on a landscape where bears outnumber people and the sockeye salmon run is the most prolific in the world. At the base of the peninsula lies Katmai National Park, a wilderness larger Yellowstone and Yosemite -- combined. Farther down the peninsula a giant volcanic caldera emerges on the horizon, so remote that more people climb Everest than visit Aniakchak. But Alaska is warming at more than twice the rate of the rest of the planet; The Ends of the Earth, John Grabowska's lyrical film on the Alaska Peninsula, asks how climate change effects will impact this magnificent land of wilderness and wildlife.
