The parchmark of the stonehole is visible in Sharpe's aerial photograph, and can be made out in the more recent one by Adam Stanford:
One of them is: "Stonehenge Station-Stone rectangle and the relevant sightlines and horizons: Most southerly moonrise/ most northerly moonset and Midsummer sunrise/ midwinter sunset".
The four station stone positions are in a rectangle that on its longest edge just grazes the sarsen circle and seems to be aligned to astronomical features as above.
Station stone 94 has recently been marked with a handsome polished sarsen stone in a stainless steel ring.
From the public path the sight line to the fallen Station stone 91 should be very close to the sarsen circle. On a visit this week trying to align the marker left a large gap. My hat indicates a closer position which seemed to match the plan and photos.

It would be nice if someone with more time and the right equipment could check if the marker position is correct or not.

It wouldn't be the first time they positioned a marker incorrectly.
I seem to recall the bronze Solstice Arrow had to be repositioned after installation. (fwiw, it still looks funny to me ...)
They went to all the trouble to make those beautiful markers - it seems to me that they'd take the extra minute and re-calibrate the GPS reader! (Or perhaps simply cast an eye from SS-91 across S-1 and -2? )
Tim , Your hat looks about right .The conversion was mostly wrong in the northing (about 7m )ReplyDelete
The grid ref converts to 50 .907965 , -1.400683 .They had 50.908028 -1.400675
Geo - I was just editing it as in cutting and pasting I had managed to get my eastings and northings the wrong way round - I think I have it right now.Delete
This gross error reminds me of the engineer's plan when they wanted to put a marker for Stone-97's hole inboard of the Heelstone!ReplyDelete
So yet again the independent researchers are more accurate than middle-management ticket counters.
I guess you have to care about these things, but seriously - how difficult would it be to do it correctly?
About 18 months the english rock art site ERA and some of ADS had taken correct grid refs but kept them in in the OSGB datum and not changed to WGS84 when converted to Co-ordinates .Resulting in a fair bit of confusion .ReplyDelete
Do you know if this ever got corrected?ReplyDelete
No it hasn't beenDelete
