Lunag Ri
Lunag Ri is a formidable 6,895-meter granite and mixed-ice mountain standing on the boundary between Nepal and Tibet in the Rolwaling Himal near the Nangpa La pass. Long recognized as one of the highest and most aesthetically striking unclimbed summits in the Himalayas, its razor-sharp West Ridge rebuffed numerous world-class expeditions, including joint attempts by American legend Conrad Anker and Austrian prodigy David Lama.
