What does this number measure?
The highest summit in North America. Denali is in Alaska. Its rise above the surrounding terrain and its elevation above sea level are two different measurements; only the latter is compared here.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue order of magnitude; a source is provided, but this measurement has not been individually audited.
