The Angry Corrie 53: Apr-May 2002
From pillar to post-completion
Congratulations are due to Fraser Clark of Hamilton who on 24 January 2002 completed the rare feat of having bagged every trig pillar on a Landranger map. It was sheet 71, wrapped up with Blacksidend (411m, 71/583295). Fraser was accompanied by Ken Stewart, himself closing in on completion for big-trig Landrangers 64 and 65. Blacksidend reportedly had a "very chilly wind but excellent views".
Ken had also been there for Fraser's first deliberate Landranger 71 trig, Blackcraig Hill (700m, 71-77/647064), 27/6/97. First overall (ie pre-trig interest) was Middlefield Law (466m, 71/680307) circa 1987. The round's most unpleasant moment came on Broken Cross Muir (265m, 71-72/843372) when the intrepid trigbagger was swiped in the eye in thick forest. By contrast, the most enjoyable outing was Black Hill above the Dalveen Pass (531m, 71-78/894058): "a nicely-shaped steep-sided hill with good views".
Ravengill Dod (538m, 71-78/917196) was also noteworthy, "as it encourages walkers to enter the area surrounded by the M74, B797 and B7040. There are no Marilyns, Donalds etc and yet it is well worth visiting. I started from the bridge near Glencaple, went up the ridge over Craig Dod to the trig, continued to Wellgrain Dod then north down the ridge on the west side of Laggen Gill. A very nice horseshoe walk and yet almost unknown."
TAC is interested to hear from anyone who has completed a map (of any scale) in this way. It's a curious game, not least because the number of trigs per sheet varies hugely and is diminishing as pillars vanish due to vandalism, quarrying, housebuilding, etc. Landranger 71 had 44 pillars before Cairngryffe Hill (340m, 71-72/943412) and Laight Farm (246m, 71/608117) went the way of all concrete.
Quite how many maps have been trig-completed is hard to assess - eg it's known that Leslie Toft visited all 108 Derbyshire trigs, but that doesn't necessarily mean he ticked off any maps, as the Derbyshire sheets all have overlaps with other counties (eg LR119 includes a 23-trig chunk of Staffs.)
One person likely to have trig-completed a few maps is Mike Wilson-Roberts, a remarkable man from Christchurch in Dorset. He climbed all the Munros in a single expedition in 1989, did the same with Corbetts in 1992 (more on this anon) and reports having visited 2753 trigs thus far.
Anyway, to mark Fraser Clark's achievement, and because no other magazine is likely to do it, here are some details for trigs on the 85 Scottish Landrangers. Due to "felling", this is a curiously inexact science - eg the trig top for LR33 has changed since Sgurr na Ciche (1040m) and Gleouraich (1036m) lost their pillars. Other vanished high-hill trigs include Beinn Ime, Glamaig, Schiehallion and Sgorr Dhearg. Then there are awkward situations where only trig fragments remain in place - eg Ben Cruachan and Ben Starav. Feedback on absentee trigs is welcome. Likewise for undiscovered/unmapped trigs, as it's notoriously hard to be sure of having spotted them all - see TAC47, p12 for some well camouflaged constructions. And feel free to contribute any name refinements, especially for low-lying pillars. The total number of surviving Scottish trigs is believed to be just over 2200 at present.
1 LR4: Highest non-inset trig: 293m, Royl Field (4/395285).
2 LRs 8 and 39 have the fewest trigs. Lowest trig on the 40x40 grid of LR8 is 66m, Tom a'Mhinister (8/372523).
3 Carn Mhartuin (538m on LR25) is the highest lowest trig. Twenty-two LR sheets have no trig below 100m.
4 LRs 26 and 62 have 2m trigs, the joint lowest.
5 Sgurr na Ciche 1040m was formerly trig top of LRs 33 and 40. LR33 also used to have Gleouraich, 1036m
6 LR41: largest low/high differential, 1340m. Has anyone walked between the two trigs? Next largest is LR44, 1076m.
7 LR46: smallest low/high differential, 123m. Next smallest is LR82, 184m. Carnan Mor is also the lowest trig top.
8 LR50: Highest complete trig is 959m, Beinn Fhionnlaidh, 50/094497. (Cruachan and Starav both just fragments.)
9 LR52: trig top formerly Schiehallion, 1083m.
10 LR56: trig top formerly Beinn Ime, 1011m.
11 LR64 has most trigs; M77 construction took at least one.
12 LR74: 23 Scottish trigs, 14 English. Actual high trig: 815m, the Cheviot (74-75/909204). Actual low trig as given.
13 LR75: one Scottish trig, 24 English. Actual high trig: 815m, the Cheviot (74-75/909204). Actual low trig: 61m, Newhouses (75/167303).
14 LR79: 49 Scottish trigs, two Eng. Actual high/low as given.
15 LR80: 23 Scottish trigs (inc Hungry Law 501m, Lamb Hill 511m, King's Seat 531m, Carter Fell 579m and Windy Gyle on Border); 25 purely English. Actual high trig: 714m, Hedgehope Hill (80/944197). Actual low trig as given.
16 LR85: 17 Scottish trigs, 21 English. Actual high trig: 303m, Warnell Fell (85/337412). Actual low trig as given.
17 LR86: No Scottish trigs (see TAC22, p15, question 10), 44 English. High trig: 673m, Killhope Law (86-87/819448). Low trig: 32m, White Moss (86/457603).
