A scientific and mountaineering team led by the U.S. Geological Survey, National Geodetic Survey, and University of Alaska – Fairbanks, has recalculated the summit elevation of Denali, Alaska’s highest peak and highest mountain in North America. The traditional elevation of 20,320 feet (6,194 m) was determined in 1952 using photogrammetric methods. In 2013, an elevation of 20,237 feet (6,168 m) was reported following an IFSAR (Interferometric Synthetic Aperture Radar) survey. The new summit elevation of 20,310 feet (6,190 m) was determined after the 2015 expedition obtained high-accuracy GPS measurements from Denali’s summit.
