I was at this site on Friday battling the wonderful English summer! I didn't find the circle so need to go back. The cross is back on the cairn, albeit a fairly flimsy wooden structure (nice to see that Christian misappropriation is still going on, but then why change the habit of 2,000 years).

Anyway, thanks for the extra info here, I now feel I can go back and find it! Strawberry Lea is a whole other story though, as the bracken is simply way too high at this time of year.
