"The Mountains of Ireland". All of Dillon's summits are over , and almost all have a prominence above (i.e. they are very similar to the list of 209 Irish Hewitts). The term Myrddyn Deweys are peaks in Ireland, between 500 metres to in height, with a prominence above , which was published by Michael Dewey and Myrddyn Phillips in 2000. Myrddyn Deweys are the Irish equivalent of Deweys, which extend the Hewitt classification down to 500 metres. There are 200 Myrddyn Deweys. MountainViews Online Database MountainViews was created in 2002 by Simon Stewart as a non–profit online database for climbers in Ireland to document and catalogue their Irish climbs. Its main data source are from the Ordnance Survey Ireland (OSI) maps, although it also conducts its own surveys, which the OSI has integrated into its own database, and it also integrates other important Irish mountain databases such as the Paul Tempan's work with the Placenames Database of Ireland (Loganim). Collins Press published the MountainView Online Datase in 2013 in the book: A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins. Since 2012, MountainViews has been partnered with the Database of British and Irish Hills (DoBIH), which is the main live database for the categorisation of mountains and hills in Britain and Ireland. However, MountainViews can differ slightly from DoBIH on the measurements for certain Irish mountains. List of the 10 Highest MacGillycuddy's Reeks The MacGillycuddy's Reeks range contains Ireland's highest mountain, Carrauntoohil , and the Reeks is the highest range of peaks in Ireland. However, many of its peaks do not meet all classification criteria for a "mountain" (e.g. particularly the in elevation change from neighboring mountains), and many are not in the 100 Highest Irish Mountains. Regardless, the range contains ten of the thirteen Scottish Furths in Ireland, and given its importance, and as an important example of complexity of mountain classification, the ten highest Reeks are listed below: 100 Highest Irish Mountains (any height, prominence over 100 m) This is the MountainViews 100 Highest Irish Mountains list, which was published by Collins Press in the 2013 book: A Guide to Ireland's Mountain Summits: The Vandeleur-Lynams & the Arderins. It combines Paul Tempan's 2012 research into Irish mountains and Irish mountain names. The list requires a prominence of over , a compromise between the popular British Isles Marilyn criteria of 150 metres (see List of Marilyns in
