Why was this list created?

Thanks to Paddy Dillon – We highly recommend his website and book, The Mountains of Ireland, (ISBN-13: 978-1852841102).  The list of Dillons are reproduced from this book by his kind permission.

How are these hills defined?

There is no criterion for re-ascent (drop), so it is subjective list with a small number of differences between the Dillons and Hewitts.

Note that if you sort by date and see dates of '01/01/1900', this indicates that when you logged or imported data for this hill, no date or an invalid date was assigned for this ascent e.g. '00/00/0000'. The 1900 date is used in this table since it's required for the correct sort order. You can edit the ascents to the correct date or year, if known, to avoid this and to get correct annual totals in 'My Progress'.
