Hi Pete,
Good to see that you are organising a party to visit the Scaleburn whimsey. unfortunateley I will not be able to be present.
However I offer a few observations! Since we put the second oil drum in it seems to have, over the years narrowed somewhat and so the level beyond seems almost impossible to get into.
It needs some enterprising group to re-do this entrance to the passage beyond!
Another interesting feature is the mineralisation both above, below and in the horse level random.
The former is accessed via a small rise just before the oil-drum. Here the way on needs you to wriggle around a large boulder in the roof, which I did years ago but last time we
attempted it I could not get around and over it.
The prize is access to a low flat which eventually leads to flat workings above /close to the horse whim.
if you need any more help please let me know.
have a good trip.
