147.7m is just a number, it earns no respect until the error bars are quantified. Or to put it another way, a precision of 0.1m means nothing unless you know how accurate it is. And even then I would prefer to know whether the survey was conducted by professional surveyors or by some odd bods with a yen and some hired gear but negligable experience. Sorry to be so negative but having assisted in a number of levelling traverses as part of site investigations I know something of how many traps there are for the unwary!
I would be in favour of avoiding all this fiddling about by declaring that the Marilyn list of a certain date, say 2009 if you like, is the permanent GB SOTA list.
Ooh you are cheeky Brian. It’s really all rather interesting…
Take a look at some of their survey reports here:
Although the Baystones report is not there yet, you will see from other recent ones (like Raw Head and Myndd y Cwm) who is doing them, the methodology they adopt and the tolerances employed. Their work seems to be well founded.
The RHB surveyors are skilled and highly respected. ISTR hearing that even the OS accepts RHB survey findings as reliable when updating its own reference data.
Personally I don’t mind a bit if successive improvements in surveying accuracy cause such slight alterations to the lists. It all adds to the interest and I appreciate the fact that an independent third party is meticulously keeping the GB P150 list in good shape.
Glad I bagged this one last year. It was my first Lake District adventure.
On the way up from Ambleside you have stunning views over lake Windermere all the way to the coast.
My wife wanted to sit down and enjoy that view. But I think it was just an excuse to have a rest. She has problems with her health. She thought she wouldn’t make it to the top but climbed Old Man of Coniston 3 days later …
Thank’s to Marc for passing on the information about the RHB survey of Baystones. I’m going to the Lakes next month so this one will be a priority activation. I fancy walking up Nanny Lane from Troutbeck and walking over the ridge from Wansfell Pike.
You’ve nothing to worry about. James M0ZZO (G AM) is the person to ask, and he normally gives ample notice in these situations. It won’t be before the official publication of the change in the MARHOFN (Marilyns Hall of Fame Newsletter) anyway, and that’s normally published at the start of May.
