Pakistan is home to 108 peaks above 7,000 metres and 4555 above 6,000 m. There is no count of the peaks above 5,000 and 4,000 m. Five of the 14 highest independent peaks in the world (the eight-thousanders) are in Pakistan (four of which lie in the surroundings of Concordia; the confluence of Baltoro Glacier and Godwin Austen Glacier). Most of the highest peaks in Pakistan lie in the Karakoram mountain range (which lies almost entirely in the Gilgit–Baltistan region of Pakistan, and is considered to be a separate range from Himalayan range) but some peaks above 7,000 m are included in the Himalayan and Hindu Kush ranges. Moreover, Pakistan is home to over 7,000 glaciers, more than anywhere except the polar regions. Considerations The list is an incomplete list of mountains in Pakistan. There are many named and unnamed peaks in Pakistan that are currently not included in this list. The list also includes many peaks that are not usually classed as independent mountains, but instead are considered sub-peaks of other mountains, due to having low topographic prominence (the height of a peak above the highest saddle connecting it to a higher summit). Also, many of the elevations listed are approximate, due to imprecise and inconsistent surveys. The ranks in the peaks above are derived from the list of highest mountains. The dividing line between a mountain with multiple peaks and separate mountains is not always clear (see Highest unclimbed mountain). A common threshold is to define a mountain as a summit with 300 m prominence (1,000 ft; also 10 traditional rope lengths). Alternatively, a relative prominence (prominence or height) is used (usually 7–8%) to reflect that in higher mountain ranges everything is on a larger scale. The list of highest mountains ranks the highest 100 summits with at least 500 m prominence, approximating a 7% relative prominence. A drawback of a prominence-based list is that it may exclude peaks commonly thought of as mountains that are connected via a high ridge to a taller summit. Many such peaks and mountains with less than sufficient prominence are included but not numbered in the list. It is very unlikely that all the heights given are correct to the nearest meter; indeed, problems of definition of sea level can arise when a mountain is remote from the sea. Different sources often differ by many meters, and many mountains in the Karakorum
