TUCSON, AZ (Tucson News Now) - Denali is the United States' tallest mountain, but it is not quite as tall as first thought.
U.S. Geological Survey scientists physically scaled the mountain in June, reaching the highest point in nine days. While on top, they used modern technology to better assess the peak. It was determined Denali had a peak elevation of 20,310 feet (6190 meters), which is 10 feet shorter than the height determined in the 1950s.
Denali was formally recognized by the U.S federal government as Mt. McKinley from 1917 until this year. However, a restoration of the original name, Denali, was requested by Republican Gov. Jay Hammond in 1975. That request was honored on Aug. 30 by the U.S. Secretary of the Interior.
Check out the detailed images below of Denali. The top image was snapped on June 15 from a NASA satellite. According to NASA Earth Observatory, images from this satellite where then "draped over an ASTER-derived Global Digital Elevation Model" to create the bottom image, which shows what a person would see when looking south at the mountain.
