A joint expedition of Burmese and US mountaineers will try to rewrite geography books by scaling Mount Ganlanrazi in Burma’s remote northeast to prove that it is the Southeast Asia’s highest peak. At 19,215 feet, nearby Mount Hkakabo Razi is currently thought to be region’s biggest mountain. But according to Mizzima news, maps drawn up by American and Soviet topographers in 1945 show that Ganlanrazi is actually 90 feet higher. The expedition, which includes two Burmese and five American climbers and is being bankrolled by the Htoo Foundation, will set out on Thursday.
