Yes TE I am andyfellwalker.com and I frequently come across objects that really don't look natural but I can't find any other explanation.
It was the posting about Troutbeck Park cairns that led me here.
For really interesting and unexplained works the best place is Stockdale Moor and Caw Fell which coincidentally were just as misty as Troutbeck Park was yesterday and equally as quiet.
