I noticed that there are only 2 summits in this region that are still un-activated which are GM/SS-173 and GM/SS-188. I see that Gerald G4OIG and Paul G4MD has been spotted on GM/SS-188 which will leave only GM/SS-173 the only un-activated in this region. I wonder who will be the first to activate the final un-activated summit in GM/SS.

There are plenty of new summits to add Jimmy, ISTR there are 5 or more changes to come.
Hi Andy,
I noticed that there are quite a few changes for the GM Association, but looking at the changes, the only change in GM/SS is to delete one SOTA summit.
Jimmy M0HGY
Isn’t there? I was sure there was a new SS along with an ES moving NW 1.5km, a new NS and a NS moving SW 1km.
Hi Andy,
From what I can see Creag an Dail Bheag replaces GM/ES-020 meaning that Creag an Dail Bheag will be a new GM/ES SOTA summit, GM/WS-344 needs to be deleted, Creag an Amalaidh is to be added to GM/NS, Creag Toll a’Choin replaces GM/WS-053 meaning that Creag Toll a’Choin becomes a new SOTA summit in GM/WS and GM/SS-257 needs to be deleted. The only other change that I can see is the change the grid reference for GM/SS-260. From this I cannot see any new Marilyns in GM/SS.

My money is on Jimmy here. 
I know this much - it’s blooming hard work trying for a completion of GM/SS as a chaser. Last count I still had 133 to get! I need more 40/60 metre phone activations rather than two metre handies!

I was sure there were some new SS summits to add. I was right, there were some new ones to add but I’ve already added them!
Creag an Amalaidh looks a nice wee lump. Ideal for breaking up journeys North (or South) on the A9 when you get up North.
I can’t believe Andy that you would forget that you have already added the 2 new GM/SS summits last year. I remember you doing this. Maybe your old age is kicking in
Jimmy M0HGY
I think I’ve seen 25k-30k new summits added since I took over the database. Not surprising you forget about the odd one or two!
You might know all the UK and EI pending updates Jimmy, but you haven’t edited your avatar yet 
And don’t be so rude about your elders. When you start to feel old age creeping up on you, it will probably be me or your mother…
Good job some of us do the tiddlers then eh Brian 
We’re working our way round them slowly, but it might take a while…

@M1EYP I have now changed my avatar on all my reflector accounts.
I meant this just as a joke.

If you type about Scottish Marilyns for long enough that nice Mr. Dawson comes along and gives you a new one!
Stob Coire a’Chairn 981.46m @ NN185660 is now a twin with An Gearanach 981.36m @ NN187669. Not quite sure how we handle twins in the database, that will need a bit of consideration.
I remember those two, with An Gharbhanach the last three summits on the Ring of Steall, as I remember it not too much in the way of ups and downs, so I would say all three summits share an AZ. It would be sensible to list them as Stob Coire a’Chairn/An Gearanach - this makes much more sense than WS-074 Aonach Eagach - Sgor nam Fiannaidh, because anybody who approaches WS-074 by the Aonach Eagach is either seriously misled or a committed munro-bagger!

I think the situation might already exist. Seager Hill rings a bell for some reason, or maybe something else in that area.
In any case, only one of the two can be listed, and whether the other of the pair would be OK for activating from would go simply on the existing AZ rule.
Your data above implies that Stob Coire a’Chairn is 10cm higher than An Gearanach, so presumably that would be the Marilyn?
And Jimmy - I know you meant it as a joke. So did I
That’s another thing. 10 cm difference. Carry a small boulder from the higher one and put it on the lower one and they would change places - ridiculous! If I remember correctly, they are both Munros (or were, I haven’t kept up to date with the revisions) which makes a nonsense of Munros, too, because although that section of the Ring of Steall is about a kilometre long the low points can’t be much more than 15 metres below the summits as I remember them. Mind you, an engrossing ridge in detail, I must come up and do it again before that old rocking chair gets me!
Pick one by the toss of a coin if we can’t have both!
Brian
We’re rather at the mercy of the folks who do the measuring.
I vaguely remember the position of my nearest SOTA summit (G/SE-005) moving something like half a mile following some bit of re-measuring. I’ve no idea whether any dumpers full of soil were involved, but at least its name didn’t change as a result, and I think its activation zone is all in one WAB square, but it did change grid square from JO01ag (which SOTAwatch still claims it’s in) to IO91xg (which is the one the summit now lies in).
I guess there’s at least the possibility that an activation area could gain or lose an adjoining bump through small movements of the relevant (25 metres or 100 feet) contour, too, if there was a saddle at the wrong altitude…
73, Rick
If 2 peaks are both within the activation zone, but one peak turns out to the higher than the official SOTA summit, you just need to amend the grid reference, height and name if applicable. This means that GM/WS-053 does not needs to be deleted as the col between Maoile Lunndaidh and Creag Toll a’Choin is only 17m, so Maoile Lunndaidh can be renamed to Creag Toll a’Choin and the hight and grid reference can be changed. I remember is for G/SE-009 where Chanctonbury Hill got moved to Chonctonbury Ring.
You only need to remove a SOTA summit and add another SOTA summit if the drop of 2 peaks is more than 25m or whatever the activation zone is in some associations.
It seems that even though Stob Coire a’Chairn is higher than An Gearanach GM/WS-069, it appears that Alan Dawson has decided to leave An Gearanach GM/WS-069 as the Marilyn and make Stob Coire a’Chairn a twin Marilyn. My understanding is only official Mariylns can be SOTA summits, not twin Marilyns. However I think this one does need to be queried with Alan Dawson.
Jimmy M0HGY
My guess is that Alan Dawson has refrained from selecting the Marilyn summit from the pair because both summits are within two sigmas of the mean height so that there is no test that can be applied to separate them. We either follow his lead (and SOTA in the UK is based on his listing) or we take the nominally highest knowing that there is a possibility that it isn’t the highest, or we take the traditional highest, which is An Gearanach (the sad place) rather than Stob Coire a’Chairn (Peak of the corrie of cairns) which has the advantage that it is very prominent from the normal approach from Steall in Glen Nevis.
