Sanjiangyuan National Park has recently released the first ever 4K high-definition panorama video footage of the source of Yangtze River, the longest in Asia. Staff at the park used high resolution cameras to record the alpine natural scenes around the river source including glaciers, snow-capped mountains, rivers, wetlands, deserts and lakes. They have also found numerous rare mammals endemic to the Qinghai-Tibet Plateau, including the Tibetan antelope, wild yak, Tibetan wild donkey and Tibetan fox.
