↑ In making any "highest mountains" list, one needs to use a criterion to exclude subpeaks and only list independent mountains. There is no universally agreed-upon such criterion. However the (generally accepted) list of fourteen eight-thousanders is obtained if one uses a topographic prominence cutoff of between 200 and 500 metres (610 and 1524 feet). Some eight-thousand metre subpeaks have been climbed as goals in themselves, for example Lhotse Middle, but this is quite rare.
