The Hewitts and Marilyns of Ireland - an update

Clem Clements' immensely detailed and pioneering TACit Table, The Hewitts and Marilyns of Ireland, was published in September 1997, following a gestation of several years. It was the first book to fully update Irish hill heights and locations using the new Discovery series of 1:50000 maps from the Irish Ordnance Survey, and has been well received by hill-tickers who bought it either as a standalone listing or as part of the ongoing series. Early sales have been steady rather than stunning, partly due to a dearth of reviews in the outdoor press. Only two magazines seem to have commented thus far: a perceptive and encouraging piece by Geoff Birtles in High, and a long, but snooty and pre-agenda-ed assessment by John Forsythe in Joss Lynam's mouthpiece-mag, the Irish Mountain Log. Nothing daunted, and even though it's still well under a year since publication, TAC continues the TACit Tables policy of providing immediate update information as and when any significant changes come in. (See also Grant Hutchison's World Tops and Bottoms update in TAC34.) The bulk of what follows will only be really meaningful to those with the book; but, with a goodly wodge of new maps recently published, there's no point pretending things are exactly as they were.

The update Table details hills where information is known to have changed in any way. The final column (Change) shows exactly which part of the original information is different, abbreviated as follows: H = height; N = name; M = map (where a previously unlisted sheet has been published); G = grid reference; D = drop (in metres). i indicates less easily categorised new information, found in the Notes beneath (eg recording those Gaelic names which appear on the map). Sections, eg 53B, remain those defined first time round, whilst ° after a name or c before a drop indicates an inexact estimate from contours (although many new drops result from previous approximations now firmed up).

Two drop figures are given: differences in definition are endlessly debated (see the book for a full attempt), but Absolute Drop relates to descent before rising to any higher hill, whilst Relative Drop is descent before rising to a Marilyn, albeit possibly lower in height. Nine 1:50000 maps have recently been published: 36, 42, 43, 46, 59, 60, 61, 68, and 69. All Hewitts are now covered by modern maps, whilst only twelve Marilyns and one SubMarilyn still rely on old cartography.

As with the original book, the update Table is in two parts. The first is devoted to Hewitts (Hills in England, Wales, and Ireland over Two Thousand feet). Irish Hewitts now total 212 (Mount Leinster East Top is the newcomer), but only three of the original 211 see any change. These three are also Irish Marilyns (hills with 150m drop), so should be replicated in the second list, but are omitted to avoid repetition. Marilyns rise by two, to 455; the newcomers, both Sect 54B, are Cullenagh Mountain (formerly a SubMarilyn), and Cullahill Mountain. The listing ends with SubMarilyn data: the total drops from 43 to 41 (Cullenagh Mtn elevation, Dho Bran demotion). Hills are listed in the same order as before.

Update information provided by Clem Clements with additional data from Tony Payne; thanks are due to both. Clem's 48pp book, beautifully illustrated by Chris Tyler, is available from TAC/TACit, price #3.70 (#4.20 inc p&p).

Dho Bran (Sect 54B) has dropped out of the SubMarilyns: OS68 gives a drop of <140m. However, two hills still only on 1/2" maps may eventually qualify as SubMarilyns: both currently have estimated drops of 137m (450ft). These are Aghacashel Hill, 249m 817ft, OS35, N550890; and Knockeyon, 214m, 702ft, OS41, N465639.

Notes

Slievekimalta: Gaelic: Sliabh Coimeálta.

Mount Leinster: Gaelic: Stua Laighean.

Mount Leinster East Top: Completely new Hewitt, ie wasn't previously even a SubHewitt.

Slieve Gullion: Gaelic: Sliabh gCuillinn. Height is 574m on OS36, but 573m on OS29.

Croslieve, Tievecrom: As of late September 1997, both these Marilyns had British army posts on their flanks, and walkers may well encounter patrols and subsequent interrogation. Obviously the situation on the ground is continually changing given progress or otherwise in the peace process, but on these hills in particular, and on lower Northern Irish hills in general (eg see Note 164 in Clem's book), aspiring summiteers should anticipate problems if climbing in twilight, or if carrying a camera or binoculars. Whilst no serious incident has yet occurred, walkers are liable to be regarded as hostile until they can prove differently. Croslieve summit is J002164 on OS36, but J001163 on OS29,36A. Tievecrom 264m on OS29,36A (unnamed on latter), but 263m on OS36.

Tountinna: Gaelic: Tonn Toinne.

Knockfeerina: Gaelic: Cnoc Firinne.

The Pinnacle: Previously given as Slievereagh, but OS73 gives this as the range name rather than the specific summit listed here.

Mauherslieve: Gaelic: Motharshliabh (unusual: possibly a map-typo).

Knockaunderrig: Formerly Silvermine Mountain (Gaelic: Sliabh an Airgid). Ireland Guide by Bord Fáilte gives Knockaunderrig.

Devilsbit Mountain: Gaelic: Bearnán Eile.

Cooneen Hill: Gaelic: Cnoc an Chuainín.

Knockanora: Gaelic: Cnoc an Fhothraigh.

Ballincurra Hill: Gaelic: Cnoc Bhaile an Charraigh.

Brandon Hill: Gaelic: Cnoc Bhréanail.

Coppanagh: Note 321 in the book flagged up a possible Marilyn switch here, with nearby Freagh Hill only one foot lower on 1/2" OS19, and with only approximately 135m of drop between. With the publication of OS68, Coppanagh has remained a Marilyn, but is now twinned with Croghan (not Freagh Hill), also 365m, at S663455. Coppanagh / Croghan (mutual drop 124m) thus comprise the third joint Marilyns, along with the Knockalla Mountain (Section 45B), and Moylussa (Section 48A) pairs.

Killoshulan Hill: Relative drop has changed due to promotion of Cullahill Mountain.

Slieveboy, Carrigroe Hill: Both these Marilyns reportedly have trig points which the new maps don't show.

Pinnacle: Previously named Coolinarrig Hill, from nearby settlements on 1/2" OS16. This new name is from OS61.

Slieve Foye: Gaelic: Sliabh Feá. Slieve na Calliagh: Gaelic: Sliabh na Caillí. Knockadigeen Hill: Gaelic: Cnoc Duíginn.
