Trig stuff extra

As mentioned in TAC53 (p8), I have visited nearly all the trig pillars on Landranger 64 (Glasgow): only the 22m Barskiven Hill pillar, at 64/455635 on the western edge of Paisley, now remains. The high LR64 trigs, on the Campsies and the Kilpatricks, were easy. By contrast Dick's Law (241m, 64/501453), set amid Ayrshire trees, took a bit of finding but was in a ride and could not be classed as difficult by Marilynbagging standards. Some formerly mapped trigs have gone, for example due to construction of the M77 extension (Corselet 138m, 64/522561, with Harelea Hill 208m, 64/520534 at risk). At least two have vanished under secondary schools at Drumchapel and Bishopbriggs (no stated height, 64/525717 and 80m, 64/622705 respectively), two into quarries at Dumbuck and Croy (166m, 64/420746 and 141m, 64/731762 respectively) while those on Haugh Hill at Pollok (37m, 64/527617) and at Hayhill above Bardowie Loch (74m, 64/576732) have been removed for no obvious reasons. (The Haugh Hill trig was oddly placed, well down one side of the hill, and is still shown on the latest LR64 but not on Exp342 - a common OS inconsistency.)

Distribution over the map is very uneven. The good viewpoints on the hill edges south of Glasgow are well supplied, while North Lanarkshire on the east of the sheet is extremely sparsely provided. There is only one trig pillar within any sort of reasonable walking distance from my house in Coatbridge (Moodiesburn 98m, 64/703700) and nothing to the south-east until either Shotts or Carluke (both beyond the edge of the sheet) is reached. The south-west corner, into Ayrshire, is also sparse.

TAC49 discussed the In Pinn rule, namely that any list tends to have one target unusually difficult of access by normal means. The In Pinn among LR64 trigs, as TAC49 went on to point out, is at Hallside primary school in Cambuslang, standing in a locked enclosure within the school grounds (46m, 64/663599). The pillar is very close to the street, but frustratingly the base plate is on the opposite side. I'd looked at it in passing a couple of times without making any formal attempt at access, but decided to have another look during the recent school holiday and this time struck it lucky.

A grass-cutting team had just arrived and the janitor opened up to allow them access. I took the chance to go in, with the janitor's blessing. The base plate number turns out to sit within an otherwise complete run of eleven - the longest in my records. Of course, access problems depend on the accessor. Just as the In Pinn or the St Kilda stacks can easily be visited by birds, so can the Hallside school trig by the local five-year-olds.
