I looked at that picture and thought how much it represented a growing number of "wild campers" and "bushcrafters." The majority, whether we are day walker/rambler/ambler''' or plain old potterer, in fact, anyone who loves nature and looking after mother earth, would do their best to leave no trace that they have been along this way
It is a problem and it is getting worse. I like looking on you tube and a number of sites are really interesting. But there are a considerable number who leave nothing as it was. One walker in a nice bit of woodland, took a morning to get rid of similar rubbish in her local woodland, including a doggie bag left hanging in a tree! She filled a bin bag with the rubbish left.
I'm not say ing that the photo hasn't been arranged but I will say that I think the only "arrangement" is to put the rubbish that the scumbags left, close enough together to have the lot in the pic. I'd bet the wood fire, the, cans and all the other detritus has been left by those who have the means to reach these sacred places; but no love for them, in fact it's the opposite, some are like Orcs and will have no feeling of shame for what they have done.
I know I'm on an orange box here but I went to pay homage a couple of years back, to Castlerigg stone circle and was sorry I went. There were tents camped in the middle of the circle with their litter arrayerd around them in a gross desecration of a place of magic.
This circle is in the middle of farm land, so god knows what the local people think about the those who gather, usually at the time of the summer solstice and to me, they are desecrating the very soul of the place of which presumably they are gathering to see the sun rise.
That's just one example of which more and more are occuring. Unbelievable really, and I guess there will be growing backlash from those who would look at all, walkers, campers (whether wild or tame!) visitors of the wild places and beauty spots like Friars Crag, in the category as the Orcs.
