If you judge countries purely by their mountainous terrain, Finland is a bit of a loser. Halti, Finland's tallest, is around 1,324 meters, or about 4,340 feet, making it a "one-thousander" as it is over a thousand meters above sea level. That may sound impressive, but bear in mind that the tallest peak in the United States is a six-thousander and Mount Everest is a eight-thousander.
