The CC Trig Point bagger thread, now incorporating other interesting geographs

Discussion in 'General Cycling Discussions' started by Drago, 19 Mar 2017.

  1. I've just noticed that various scales/ages on the National Library of Scotland OS online site appear to show masons marks (that's what the symbol looks like)
    Granted some buildings may not be there now/rebuilt

    Have a look at this one, in the town I live it
    It's marked as being on top of the railway bridge, over the very busy station/sidings, as they were then

    I have checked with @Drago , out of courtesy, about adding what could be considered a 'spoiler', as he started the thread, & he's fine with it

    Everyone seems to be using the the point where the three paths meet and the current road junction for Edge End. The Trig Point is further North and on the Eastern side of where the wall was. The Traversing Point/Bench Mark/Boundary Post is on the Western side of the wall, slightly further South.

    @Richard A Thackeray, you've got me overthinking this again with that link!

    These marks were used as markers in many cases to point to water, sewage etc locations, I'm winging it on this this but I tend to see these arrow marks (without the top levelling marks) on much older properties than from when the OS started the 'mass' marking of levelling. This is my own view as I've not researched this any further, all a guess, I'm afraid.
    Some of these marks are pretty brutally done.

    I've mentioned this before the triangle with a dot in the middle was used by map makers to signify a hill top in earlier days, OS just adopted the mark later as a Trig mark.

    The NLS map resource is amazing and It's Scottish, keep out you southerner whippersnappers^_^

    That's why there's a "Buy Button" at the bottom!

    I've spent the morning searching Google for a definitive answer,
    I'm throwing the towel in..just now

    Contact OS and maybe they can fill you in...
    I'd a discussion on my blog about White trigs

    Found this and point 5 is interesting

    Extract from Ordnance Survey 1/2,500 Conventional Signs circa 1923
    (first trig point erected circa 1936)

    Link to earlier circa 1896 HERE

    Hopefully the 1923 one answers both Richard and Classic's questions form earlier, I assume other points (hill tops) were used for the purpose of triangulation pre 1936 when someone sat down and rethought the whole thing out.

    Some asides about the trig pillar HERE HERE HERE

    Two today..

    matched the coordinates and description,
    Greenock, Bow Rd (Google Maps shows the levelling line better than my photo:blush:)
    NS 2648 7603 Greenock, Bow Rd, Wall.jpg

    Bridge of Weir, Torr Rd (normally fly down this road but have been recently doing the drag up to the B road)
    Post is worn at the top but as previous, everything matches the description in the database.
    There is something 'written' below the mark but can't make it out
    NS 3669 6597 Bridge of Weir, Torr Road, Post.jpg

    Charlestown Road, on what was a goods yard
    Wishful thinking?
    Not as clear in the picture.
    Approx 300 yards further on, and the last that will be seen on that side. (Road level raised some years ago, to even out the slope.)

    Would it be fair to say that the two on North Bridge, are now lost?
    This due to the pavement & road level being raised. The "Clover Leafs" were above knee height at one stage.

    A few from today’s ride.


    A benchmark I’ve not noticed before on the Hill up through Great Houghton.


    A utility marker about to get lost in the undergrowth near Blisworth.


    And, finally, Flush Bracket 1786, in Newport Pagnell High St.

    Rivet: Halifax, 6 Carlton Street
    Carlton Street, junction with Ferguson Street
    What was the Freemasons Lodge. Main enterance. Junction of Blackwall and Bull Close Street
    BM or not? The top line is short, but either side of point of the arrow, are 3/4 inch circles.

  15. Whilst out/about today, & keeping an eye on some of the older buildings

    1. 'Stevensons Bridge'
    I'm never certain whether the implication is the famous father/son, of civil engineering/railways fame, but their name is with a 'ph'

    2. Baptist Chapel (1877)
    High Street
    Bench Mark is on the corner
    DSCF4501.JPG DSCF4503.JPG

    3. (junction of) Ashgap Lane & High Street
    An attempt to bring the sharp turn, that was here, before a re-alignment, to prevent vehicles heading down the steep Ashgap Lane
    The house behind was a Doctors Surgery for many years
    The arrow would be just behind the photographers right shoulder in this 'Geograph' image
