Bull Elephant Reveals an Ancient Migration Path | The Long Walk Home | BBC Earth

Tracking and old bull elephant may lead us on a path to discovering the ancient paths of Angola. Thousands upon thousands of elephants struggle through a dust-laden, apocalyptic landscape. Whirlwinds of sand a thousand feet high whip the desiccated moonscape. It is a journey that some will never complete. This is a story of vision, struggle, hope and one man's dream to bring freedom to over a hundred thousand beleagured African elephants.
