North America's tallest peak just got shorter.

New technology used by the U.S. Geological Survey (USGS) discovered that Mount McKinley in Alaska stands at only 20,237 feet, 83 feet shorter than previously thought.

The finding was made as part of an USGS effort to update and refine Alaska's topographic maps.

Also known as Denali, mountain climbers who have proudly listed their feat of 20,320 feet since 1952 can rest assured that Mount McKinley remains the tallest in North America.

One of the more famous attempts to climb the mountain was recorded in 1910.
