Trigs by Bus - easy walk through the field to the south but prevented from reaching the pillar by the now infamous ditch, tried the path from the west but chest high nettles, thistles and brambles made it impassible. Almost :(

Third visit. The water in the ditch was low enough for me to find the concrete pipe. As you look at the small signs telling you of the pipe, it is 2m to the right and runs diagonally across the ditch. In the bank there is a concrete pad which states the pipe is below. The pipe runs from the pad to the marker pole on the other side, there is also a concrete pad on the other bank. Trampling down the reeds to be used as a mat and using my pole to make sure i kept close to the pipe i made it across the ditch and into the nettle / thistles on the other side.

Like A1 mushroom before us we tramped around the edge of a very very muddy field to almost within touching distance, well if two trig geeks in their late sixties could have long jumped over the water channel we would have touched it. Got a pic and we will come back in the summer via the sea path hopefully ???

Parked next to the field entry. Walked around the field through the ankle deep mud and found the dyke lapping the edge of the field. Due to the snow coming in side ways and the wife waiting in the car i didn't venture to far towards the sewage works to cross onto the other side and walk back along through the vegetation. Viewed the trig at a distance with a view to coming back in the spring / summer when the water level in lower.

Perhaps, rather unwisely, I didn't prepare for this one, and set off with my usual optimism not realizing there was a tricky little stream of water to cross. All seemed well, for I spotted the pillar within minutes. All I had to do was cross the water. Should I take a running jump? Maybe not in wellies, I decided. Headed westwards hoping to come across a footbridge, but none appeared. Eventually reached the Waterworks track and a 'bridge over troubled water', and crossed there. Then the fun began! Crashed and thrashed my way through soaking vegetation taking what seemed ages before finally meeting up with pillar S4821 on its plinth. Cap in place; one s/h open. Continued eastwards until reaching a Recycling Centre where a helpful employee kindly directed me out to freedom!

re-visit after failed attempt in summer due to vegetation. Much easier late Sept. The bridge (pipe cover - looks like MDF but is metal) is at NS 97215 80591). I have left a wooden plank on the banking pointing down to this

I avoided the dreaded ditch by going from the recycling site to the east. Had to get past the "Meet and Greet" staff on the gate. They said it was not really permitted but I could go because there weren't any gaffers about. Easy walk. Just need to follow the wide grassy track with the BP Pipeline markers.

Visited this in the winter many years ago. Made the mistake of revisiting in mid summer. Chest high thistles, nettles etc Horrible horrible horrible.

It's in there!

Easily found but only thanks to excellent directions from previous visitors. Crossed ditch at gas pipe easy but definedly required wellies after recent rain fall. Advise to visit in winter/spring when vegetation is low.

Pillar with the lowest elevation visited. Followed the field boundary next to the factory units and crossed the drainage ditch using the concrete pipe protection by the marker some 30 metres east of the pillar. Got very wet as the field was in oil-seed rape and visited after a heavy shower. Good views if you like oil refineries.

Finally visited this fairly notorious pillar. In good condition apart from some chunks missing from the top corners and screed. Not full-on damaged, in my opinion (though not far off it). FB faces west-ish with east-ish sighthole open only. Views to Grangemouth is about it due to incredibly low altitude (and freezing fog not helping). Cap present with sunken lettering. Accessed the trig from the parking to the WNW and followed the moat down until at the trig. There are two crossing points making access to the trig fairly simple. Considering this is November, the vegetation is still pretty fearsome!

Easier than expected from Belgica Furniture. Round field edge, then over ditch by gaspipe marker - plank still there.

Second visit here, a lot harder to get to pillar now. Very overgrown with nettles and thistles. Best way in is from recycle yard to the east.

Approached from the road that goes toward the water works, and then crossed the ditch by a plank someone had kindly left; along the top of banking till I reached the pillar.

Parked in Belgica car park and went across very clarty field and jumped the ditch. Hard work for such a low trig.

Bits missing off the corner. A few too many to be merely slightly damaged. An infamous beast, in thick undergrowth and guarded by a ditch and a landfill site. Went in from the west and found the crossing point near the pipeline marker. Nettlewhacked to the pillar. One of the lowest in Scotland at 4m.

All top edges and arises are chipped. One edge has spalled right back to the spider. Jumped the stream, glad I didn't hit looked really skanky!

Went down track to west - entrance has a water company notice - to where track bends West. Room to park about 4 cars. The ditch goes under road near here so you can get up onto the bank few yards to West. Trig is not in the wasteland of the dump but next to ditch. Best to visit in Winter when vegetation has died back.

Last of three consecutively numbered fourth order pillars added to secondary block NS77 in 1948, two to three years after the secondary and tertiary stations of NS77 were built. Pillar has minor damage to the top but is otherwise in good condition. Spider retains original OS plug with deep stamped font. FB faces WNW. Access is difficult due to long stagnant drainage ditch. Trig should be approached from SE via arable field. The only known crossing point over the ditch is at NS97218_80594 where a marked pipeline is buried. The trig is on wasteland and it is necessary to fight through, brambles, nettles and thistles to reach it. View to BP oil refinery at Grangemouth. Weather sunny. Originally visited in 1985, revisited and photographed 24/08/2003, GRP.
