Hi Kammer, I'm a bit confused by that picture you linked with the hill visible thru the tree (not confused by the technique, just can't place the view/hill in question!)

It doesn't look like the Whimble (and I can't remember a tree so close to the 4 stones between themselves and the Whimble) so it may well be Burfa Camp, which would be across the lane in a sightline, where there are the nearest trees to the stones.

Look at the small pic bottom right of the page linked above to see the almost identical Burfa view in your referenced cutout pic. So Burfa itiswas!

hmmm, etymology of 'Whimble' has had me stumped for ages.

In the absence of older spellings, it's fishing about in the dark somewhat. Would like to see older maps. Hmm, will look at old-maps when it's back up.

Literally speaking, 'wimble' described a hole-boring tool, gimlet, auger etc.

'whimble straw' is mentioned, and thare families of Whimble and Wimble.

Will get back to you.
