Sub–Majors by height
In 2006 , mountain database publisher , Mark Trengove , added a list of seven `` Sub–Majors '' ( to Dawson , Woodall , and de Ferranti 's P600 `` Majors '' ) , which had a prominence of between 590–600 m ( 1,940–1,970 ft ) , and which possibly could become P600s , or Majors , in the future due to any possible discovered `` contour uncertainty , rounding error , or map error '' . [ 9 ] [ 10 ] Since 2006 , one of Trengrove 's Sub–Majors , Moel Siabod , was re–surveyed and shown to be a P600 `` Major '' . The list below is the October 2018 DoBIH [ b ] list of the six mountains with a prominence between 590–600 m ( 1,940–1,970 ft ) in the British Isles . Munro : Height over 3,000 feet ( 914 m ) , and on the SMC Munro list . Furth : Height over 3,000 feet ( 914 m ) , and on the SMC Furth list . County Top : Highest mountain in the County ( `` CoU '' § DoBIH codes ) .
This is a list of P600 mountains in Britain and Ireland by height. A P600 is defined as a mountain with a topographic prominence above , regardless of elevation or any other merits (e.g. topographic isolation); this is a similar approach to that of the Marilyn, Simms, HuMP and TuMP British Isle mountain and hill classifications. By definition, P600s have a height above , the requirement to be called a mountain in the British Isles. The P terminology is an international classification, along with P1500 Ultras. P600 and Majors are used interchangeably. , there were 120 P600s in the British Isles: 81 in Scotland, 25 in Ireland, 8 in Wales, 4 in England, 1 in Northern Ireland, and 1 in the Isle of Man. The 120 P600s contained 54 of the 282 Scottish Munros, and 10 of the 34 Non-Scottish Munros (or Furths), all of which have prominences above , and are sometimes called the Super-Majors. The list also contained the highest mountains in Scotland, Wales, Ireland, and England.
