That would be great. Unfortunately I don't have a GPS at the moment but a plan would certainly help. I don't think a proper survey has been done of these in recent years (if at all!). I was quite unprepared for what I found so I think another visit is order and this time I will begin to plot the site out (cattle permitting). Time to get a GPS!
If anybody else wants to see if they can help unravel this place then let me know...it's a big place to plot on your own...
