They define landscapes, people risk their lives to climb them, and they can even make their own weather. Mountains often serve as geographic features that determine natural borders of countries. Their height can influence weather patterns, stalling storms that roll off the oceans and squeezing water from the clouds. And many are the subject of myth and legend, both expressions of nature's power and symbols of the sacred. Mountains is arranged by geographical region, featuring the greatest, most spectacular, most infamous and legendary mountains from every part of the world.
