A Chinese influencer known as “Glacier Bro” is presumed dead after he was last seen on video losing his balance near icy waters in Tibet. Wang Xiangjun — who gained an online following by posting videos of visiting glaciers — was exploring a waterfall when he disappeared Dec. 20 in Lhari County in northern Tibet, BBC reported. Footage posted on Chinese social media platforms showed the 30-year-old slip near the base of the waterfall into the quick-flowing, frigid waters, the outlet reported. Local authorities said they launched search efforts, but haven’t been able to find him.
