Mount Sisu

Mount Sisu is a mountain in the Antarctic. Finnish mountaineers Veikka Gustafsson and Patrick Degerman were the first people to ascend it, in 1997. It was named after the Finnish concept of sisu, meaning a sense of steadfast, rugged perseverance. The name has not been officially sanctioned by the United States Geological Survey, as it is not found on their Geographic Names Information System,^[1] nor does it meet the organization's standards for geological nomenclature on the Antarctic continent.^[1]
