The Sister Lakes of Haizi Mountain are a dazzling pearl on the Sichuan-Tibet Highway. The Haizi Mountain Nature Reserve, located between Batang and Litang, is the largest ancient glacial relic on the Qinghai-Tibet Plateau and is known worldwide as the "Daocheng Ancient Ice Cap." The reserve covers 3,287 square kilometers, with an average altitude of 4,500 meters. The highest point in the area, Guoyin Rize, stands at 5,020 meters. As global temperatures rise, the ice cap gradually melts, and snowmelt accumulates in glacial depressions and rock basins, forming lakes. Over 1,000 "lakes" of varying sizes exist across the mountain. The "Sister Lakes" (also known as "Glass Lakes") lie quietly on Haizi Mountain, like two beautiful, shy maidens awaiting marriage, a scene of divine purity. Surrounded by snow-capped peaks, they resemble two shimmering pearls, like two tears of the snow-capped mountains, shed at the foot of the mountain. This sacred, tranquil beauty will linger in your memory for a lifetime. The tenth issue of China National Geographic in 2006 featured this lake on the cover.
