 Regarding whether or not peaks in excess of 13,999 feet should be considered as "thirteeners", this article will count them as such for statistical purposes, but concentrate its focus on those peaks less than 14,000 feet since the higher peaks are already covered in the fourteeners list.Not all summits over 13,000 feet qualify as thirteeners, but only those summits that mountaineers consider to be independent.Objective standards for independence include topographic prominence and isolation (distance from a higher summit), or a combination.
